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 (EBCM) sets a diagnostic trouble code (DTC), the EBCM sends a class 2 message to the IPC to command the ABS Indicator ON.
