5-254 Antilock Brake System
ABS Indicator
The ABS is located in the instrument cluster and will
illuminate if a malfunction in the ABS is detected by the
Electronic Brake and Traction Control Module (EBCM).
The ABS Indicator informs the driver that a condition
exists which results in turning off the Antilock
brake and traction control function if equipped. If only
the ABS Indicator is on, normal braking with full
power assist is available. If the BRAKE and Antilock
Indicators are on, a problem may exist in the hydraulic
brake system. Refer to Brake System Testing in
Hydraulic Brakes. Conditions for the Antilock Indicator
to turn on are as follows:
1. ABS malfunction detected. As previously
described, the ABS Indicator turns on when
a problem has been found in the ABS. The ABS
Indicator indicates that the ABS and TCS if
equipped have been disabled.
2. Instrument Panel Cluster bulb check. When the
ignition is turned to RUN, the ABS Indicator will
turn on for approximately three seconds and then
turn off.
• Illumination of the BRAKE warning Indicator
may indicate reduced braking ability.
" Illumination of the ABS Indicator without the
BRAKE warning Indicator on indicates only
that Antilock braking is no longer available.
Power assisted braking without Antilock control
is still available.
" Refer to Brake System Testing in Hydraulic
Brakes for diagnosis of any condition which
causes the BRAKE warning Indicator to
illuminate.
