Trouble Codes Cannot Be Retrieved
- Measure resistance between ground and diagnostic terminals. See Figure . If resistance is less than .5 ohm, go to next step. If resistance is more than .5 ohm, repair diagnostic terminal wiring harness.
- Turn ignition off. Connect diagnostic terminal to ABS diagnostic connector terminal No. 6. See Figure . Disconnect ABSCM/HU connector. Measure resistance between ground and ABSCM/HU connector terminal No. 4. See Figure . If resistance is less than .5 ohm, go to next step. If resistance is more than .5 ohm, repair wiring harness between diagnostic connector or ABSCM/HU connector.
- Check contact at ABSCM/HU connector. If connector contacts are poor, repair connector. If contacts are okay, replace ABSCM/HU.
