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.
PIM Reset Procedure
The PIM reset procedure is only required when moving a known good PIM from one vehicle to another for the purpose of diagnosing the vehicle.
When a PIM has been installed into a vehicle, it is security linked to the BCM and the ECM. Once this linking has been performed, the PIM cannot be installed in any other vehicle unless the security linking between the BCM and the ECM has been reset. To reset the PIM refer to Service Programming System (SPS) .
