Electronic Brake Control Module: Service and Repair






REMOVAL
Pre-removal Operation:
- Under Cover removal and Installation.

Follow removal steps outlined in illustration.

INSPECTION
Terminal Voltage Check Chart





1. Connect a needle-nosed wire probe (paper clip etc.) to a voltmeter probe.
2. Insert the needle-nosed wire probe into each of the ABS-ECU connector terminals from the wire side, and measure the voltage while referring to the check chart.

NOTE:
1. Measure voltage with the ABS-ECU connectors connected.
2. You may find it convenient to pull out the ABS-ECU to make it easier to reach the connector terminals.
3. Checks don't have to be carried out in the order given in the chart.

CAUTION: Short-circuiting the positive (+) probe between a connector terminal and ground could damage the vehicle wiring, the sensor, ABS-ECU, or all three. Use care to prevent this!

3. If voltmeter shows any division from standard value, check the corresponding sensor, actuator and related electrical wiring, then repair or replace.
4. After repair or replacement, recheck with the voltmeter to confirm that the repair has corrected the problem.

Terminal Resistance And Continuity Checks

1. Turn the ignition switch to OFF.
2. Disconnect the ABS-ECU connector.
3. Measure the resistance and check for continuity between the terminals of the ABS-ECU harness-side connector while referring to the check chart.

NOTE:
1. When measuring resistance and checking continuity, a harness for checking contact pin pressure should be used instead of inserting a test probe.
2. Checks do not have to be carried out in the order given in this chart.

CAUTION: If resistance or continuity checks are performed on the wrong terminals, damage to the vehicle wiring, sensors, ABS-ECU, and/or ohmmeter may occur. Use care to prevent this!

4. If the ohmmeter shows any deviation from the normal condition, check the corresponding sensor, actuator and related electrical wiring, and then repair or replace.
5. After repair or replacement, recheck with the ohmmeter to confirm that the repair or replacement has corrected the problem.
