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.
Instrument Panel Module (IPM)
The IPM is used by the CTD to control light and horn pulsing during the alarm mode. When CTD is in alarm mode, the RIM sends a serial data message to the IPM to pulse the lights and horn. Though the IPM is lighting master, it only physically controls the front vehicle lighting. When an alarm mode is received by the IPM, the IPM will send a serial data message to the RIM, which physically controls the rear vehicle lighting, to pulse the rear lamps.
