Pinpoint Test G - Anti-Lock Light Not On When Ignition Is On
- Ensure fuses are okay. If fuses are okay, check for power at light socket. If voltage is not about 12 volts, repair ignition feed circuit. If voltage is about 12 volts, go to next step.
- Check warning light bulb. Replace bulb as necessary. If bulb is okay, check continuity between light socket and breakout box pin No. 52. If continuity exists, go to next step. If continuity does not exist, repair circuit No. 603 (Dark Green wire).
- Inspect diode for damaged, loose or bad connections. Diode is located in wiring harness, near right front of vehicle. Ensure diode is not installed backward. Replace diode if it is damaged or installed backward. If diode is good, verify symptom still exists.
