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.
Circuit Description
The instrument panel cluster (IPC) turns the ABS indicator on during the IPC bulb check for approximately 3 seconds when the ignition switch is turned to the ON position. If the electronic brake control module sets a diagnostic trouble code (DTC) the EBCM sends a class 2 message to the body control module (BCM) and the (BCM) sends a class 2 message to the IPC to command the ABS indicator on.
