9. Using a test light connected to B + , probe each of the PCM ground terminals to ensure that a good ground is present. Refer to PCM Terminal End
View for terminal locations of the PCM ground circuits.
12. In this step, temporarily substitute a known good relay for the PCM relay. The horn relay is nearby, and it can be verified as "good" simply by
honking the horn. Replace the horn relay after completing this step.
