Circuit Description
The instrument panel cluster (IPC) turns the antilock brake system (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 (EBCM) DTC, the EBCM sends the IPC the command to turn the ABS indicator ON.
