Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Isolate ICM/Pip Fault
With key off, disconnect PCM. Connect LED test light leads between breakout box pins No. J43 (PIP E) and J7 (ground). Crank engine. If LED test light blinks, replace PCM. If test light does not blink, check PIP for short to ground or power. Repair any problems found. If no problems are found, replace ICM.
