- Ensure stoplights operate properly. Connect ECU tester to ECU main harness. DO NOT connect tester to ECU. Measure voltage between harness terminals D2 (positive) and A26 (negative).
- Press brake pedal. If battery voltage is present, switch is okay. If battery voltage is not present, repair open in Green/White wire and ECU terminal D2.
