Brake Switch Signal

WARNING: This page is about a different car, the 1995 Acura 2.5TL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure stoplights operate properly. Connect ECM Test Harness (07LAJ-PT3010A) to ECM main harness. DO NOT connect test harness to ECM. Measure voltage between test harness terminals D12 (positive) and A26 (negative). See Figure .
  2. Depress brake pedal. If battery voltage exists, switch is okay. If battery voltage does not exist, repair open in Green/White wire and ECM terminal D12.
NOTE: Fast idle thermovalve is factory adjusted and should not be disassembled.
