Stability System

STABILITY SYSTEM ACTIVE -55 (WITH DIC)
The IPC illuminates the STABILITY SYSTEM ACTIVE - 55 indicator in the DIC when the Electronic Brake Control Module (EBCM) detects that the enhanced stability system, the ABS system, or the traction control system is active. The IPC receives a class 2 message from the EBCM requesting illumination. The LOW TRAC indicator also illuminates when the STABILITY SYSTEM ACTIVE - 55 indicator illuminates.

SERVICE STABILITY SYSTEM -54 (WITH DIC)
The IPC illuminates the SERVICE STABILITY SYSTEM - 54 indicator in the DIC when the following occurs:
^ The electronic brake control module (EBCM) detects a malfunction in the enhanced stability system. The IPC receives a class 2 message from the EBCM requesting illumination. The IPC sends a class 2 message to the radio in order to activate an audible warning.
^ The IPC detects a loss of class 2 communications with the EBCM and the discrete back-up ABS indicator signal circuit is high.
