Pinout Values and Diagnostic Parameters
ABS-ECU Terminal Resistance and Continuity CheckCAUTION: 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.
NOTE:
- When measuring resistance and checking continuity, a harness for checking contact pin pressure should be used instead of inserting a test probe.
- Checks do not have to be carried out in the order given in this chart.
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.

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.
