2014 - Mazda2 - Steering ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS

On-Board Diagnostic (OBD) Test Description The OBD test inspects the integrity and function of the EPS and outputs the results when requested by the specific tests. On-board diagnostic test also:

Provides verification after repairs to ensure that no other faults occurred during service. The OBD test is divided into 2 tests: Read/clear diagnostic results, PID/Data monitor and record.

Read/clear diagnostic results

This function allows reading or clearing of DTCs in the EPS CM memory.

PID/Data monitor and record

This function allows access of certain data values, input signals, calculated values, and system status information.

Reading DTCs Procedure 1. Connect the M-MDS (IDS) to the DLC-2. 2. After the vehicle is identified, select the following items from the initialization screen of the IDS. a. Select “Self Test”. b. Select “Modules”. c. Select “EPS”. 3. Verify the DTC according to the directions on the screen. If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection. 4. After completion of repairs, clear all DTCs stored in the EPS CM. (See Clearing DTCs

Procedures .)

cardiagn.com

Provides a quick inspection of the EPS usually performed at the start of each diagnostic procedure.

Clearing DTCs Procedures 1. Connect the M-MDS (IDS) to the DLC-2. 2. After the vehicle is identified, select the following items from the initialization screen of the IDS. a. Select “Self Test”. b. Select “Modules”. c. Select “EPS”. 3. Verify the DTC according to the directions on the screen. 4. Press the clear button on the DTC screen to clear the DTC. 5. Switch the ignition to off. 6. Switch the ignition to ON and wait for 5 s or more. 7. Perform DTC inspection. (See Reading DTCs Procedure.)

PID/Data Monitor and Record Procedure 1. Connect the M-MDS (IDS) to the DLC-2. 2. After the vehicle is identified, select the following items from the initialization screen of the IDS. a. Select “DataLogger”. b. Select “Modules”. c. Select “EPS”. 3. Select the applicable PID from the PID table. 4. Verify the PID data according to the directions on the screen. NOTE: The PID data screen function is used for monitoring the calculated value of input/output signals in the module. Therefore, if the monitored value of the output parts is not within the specification, it is necessary to inspect the monitored value of input parts corresponding to the applicable output part control. In addition, because the system does not display an output part malfunction as an abnormality in the monitored value, it is necessary to inspect the output parts individually.

2014 - Mazda2 - Steering PRECAUTION

Intermittent Concern Troubleshooting

Vibration method

If a malfunction occurs or becomes worse while driving on a rough road or when the engine is vibrating, perform the following steps.

There are several reasons why vehicle or engine vibration could cause an electrical malfunction. Inspect the following: Connectors not fully seated. Wiring harnesses not having full play. Wires laying across brackets or moving parts. Wires routed too close to hot parts. An improperly routed, improperly clamped, or loose wiring harness can cause wiring to become pinched between parts. The connector joints, points of vibration, and places where wiring harness pass through the firewall, body panels and other panels are the major areas to be inspected.

Inspection method for switch and/or sensor connectors or wires

1. Connect the M-MDS to the DLC-2. 2. Switch the ignition to ON (engine off). NOTE: If the engine starts and runs, perform the following steps at idle. 3. Access PIDs for the switch you are inspecting. 4. Turn the switch on manually. 5. Slightly shake each connector or wiring harness vertically and horizontally while monitoring the PID.

cardiagn.com

NOTE:

If the PID value is unstable, inspect for poor connection.

Inspection method for sensors

2. Switch the ignition to ON (engine off). NOTE: If the engine starts and runs, perform the following steps at idle. 3. Access PIDs for the switch you are inspecting. 4. Vibrate the sensor slightly with your finger. If the PID value is unstable or a malfunction occurs, inspect for poor connection and/or poorly mounted sensor.

Connector terminal inspection method

1. Inspect the connection of each female terminal. 2. Insert the male terminal to the female terminal and inspect the female terminal for looseness.

2014 - Mazda2 - Steering GENERAL PROCEDURES (STEERING) WARNING: Always inspect the steering component carefully for any shock or impact which may have occurred during a collision or servicing operation. If a damaged part or a part suspected of being damaged is used, it could result in an unexpected accident due to the steering mechanism being inoperative. Always replace the damaged part or part suspected of being damaged.

Turn off the ignition switch when servicing the vehicle with the tires raised such as when the vehicle is lifted. Otherwise, the steering mechanism may actuate accidentally while servicing, resulting in serious injury. Set the steering wheel in the straight ahead position and switch the ignition to off before performing the procedure. If the procedure needs to be performed with the ignition switch ON or the engine running, remove the main fuse (EPAS 60A) from the EPS system before servicing. Handling the air bag module improperly when working on the steering component parts can accidentally deploy the air bag, causing serious injury. Read the service warnings and cautions before handling the air bag module. (See AIR BAG SYSTEM SERVICE WARNINGS .) (See AIR BAG SYSTEM SERVICE CAUTIONS .) If the steering column is dropped, the EPS CM could be damaged internally causing the steering mechanism to become inoperative, which could result in an unexpected accident. Always replace the steering column if it has been subjected to an impact. CAUTION: If the steering column is stored in a humid place, the EPS system may not operate properly when installed to the vehicle. Store the steering column in a suitable place. If the steering shaft is installed after it has been rotated 360 degrees once accidentally while servicing, the absolute steering angle position is erased from the EPS CM and a steering angle sensor malfunction is detected. After servicing, always carry out the EPS steering angle configuration so that the EPS operates normally. (See EPS STEERING ANGLE CALIBRATION .) Before performing the work on the steering wheel, set the steering wheel to the straight-ahead position while the ignition is switched ON, then switch the ignition to off. Without this procedure, a malfunction may occur in the EPS system after completing the work on the steering system. Be careful when handling the steering column because it weighs approximately 10 kg {22 lb} and it could fall off and be damaged while servicing. If the intermediate shaft is connected to the steering gear (pinion) before installing the steering column to the dashboard member, the weight of the steering column could cause damage to the intermediate shaft slider/bush/yoke. Always follow the procedure in the Workshop Manual. The universal joint could be damaged if subjected to an impact when the intermediate

If the steering mechanism is turned from lock to lock continuously or the steering rack terminal limit is reached repeatedly, such high-load steering action increases the temperature of the steering column (to approx. 85 °C {185°F}), causing severe burns. Be careful when handling the steering column.

shaft (pinion) is disconnected. Perform the servicing carefully avoiding impact when disconnecting the intermediate shaft from the steering gear (pinion). Do not touch the EPS CM connector terminals, since static electricity could damage the electronic circuit. Do not release the lock of the tilt lever when handling the steering column unless it is securely installed to the dashboard member. If the tilt lever is unlocked with the steering column not securely installed, the steering column and other parts could be damaged. A new steering column is shipped in a pre-set condition. Maintain this condition until the steering column is completely installed to the dashboard member so as to avoid damage during transportation and installation. When removing/installing the steering column, keep the wiring harness away from the steering column installation area so as to prevent the steering column from being caught in the wiring harness and damaged.

cardiagn.com

The joint bolt for the steering column and intermediate shaft shown in the figure cannot be reused and a new bolt cannot be obtained. Therefore, never loosen or remove the bolt. If the bolt is mistakenly loosened or removed, replace the steering column assembly.

NOTE: When installing a replacement part, be careful not to rotate the steering shaft until the installation has been completed. In order to completely interrupt the EPS system power supply, do not disconnect the battery for 20 s or more after the ignition is switched to off. Do not replace the steering column (EPS system) with that of another vehicle even if they are the same model. Before connecting the EPS CM connector, remove the fuse or disconnect the battery to interrupt the power supply completely. Verify that all the connectors are securely connected after finishing the work on the steering system.

Wheel And Tire Installation 1. When installing the wheels and tires, tighten the wheel nuts in a criss-cross pattern to the following tightening torque.

Tightening Torque 88—118 N·m {9.0—12 kgf·m, 65—87 ft·lbf}

1. Disconnect the negative battery terminal before performing any work that requires handling of connectors. (See BATTERY REMOVAL/INSTALLATION [MZR 1.5].)

Suspension Links Removal/Installation NOTE: To prevent the bushings from being twisted or pinched, perform the procedures with no passengers or luggage aboard the vehicle. 1. For the joint sections with rubber bushings, raise the vehicle using a lift and temporarily tighten the installation nuts and bolts. Afterwards, tighten to the specified torque with the wheels on the ground.

EPS Related Parts CAUTION: If the EPS CM configuration is not completed, the EPS will not operate properly. If the steering column component (EPS CM) is replaced, always carry out the EPS CM configuration so that the EPS operates properly. If the EPS steering angle calibration is not completed, the EPS will not operate properly. After completing the following work, if the EPS warning light illuminates or flashes when the steering wheel is turned lock-to-lock with the engine started, always carry out the EPS steering angle calibration so that the EPS operates properly. Steering column (EPS CM) removal/installation Intermediate shaft disconnection 1. Make sure that there are no DTCs in the EPS memory after working on EPS related parts.
