Traction Control System Indicator(s): PCS

The IPC illuminates the PCS indicator when the electronic brake control module (EBCM) detects a malfunction in the precision control system (PCS). The IPC receives a class 2 message from the EBCM requesting illumination of both the PCS indicator and the TRAC OFF indicator. The EBCM disables both the precision control system and the traction control system.
