3. Turn ignition off. Disconnect ABS CM connector. Measure voltage between terminals "A" and AB of
ABS CM harness connector. See Fig. 3
. Also, measure voltage between terminals "A" and AC of ABS
CM ha rness connector, and between terminals "A" and AM of ABS CM harness connector. If battery
voltage is present, go to next step. If battery voltage is not present, repair wiring harness.
4. Turn ignition off. Reconnect ABS CM connector. Drive vehicle and recheck ABS warning light. If ABS
warning light illuminates/goes out with vehicle stopped and during driving, replace ABS CM. If ABS
warning light does not illuminate/go out with vehicle stopped and during driving, a temporary poor
contact in wiring may have occurred and ABS is now functioning properly.
ABS WARNING LIGHT INDICATES NORMAL, BUT ABS DOES NOT OPERATE PROPERLY
Check for ABS DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES
under DIAGNOSIS &
TESTING. If no DTCs are present, inspect mechanical system.
PRE-DIAGNOSIS INSPECTION
Visually inspect ABS components for possible cause of anti-lock problem. Visual inspection may help identify
cause of a simple malfunction. Ensure ABS warning light is functioning properly. See TROUBLE
SHOOTING .
ABS warning light illuminates under the following conditions:
Vehicle operated on snow or ice with parking brake activated, or a dragging brake at one wheel.
Different size tires being used.
Tires with different traction characteristics are used on same axle.
Vehicle is jacked up and drive wheels spin for 20 seconds or more with ignition on.
Low battery voltage.
If ABS warning light illuminates because of these conditions, turn ignition off, then back on. ABS warning light
will go out and no DTCs for described conditions will be stored in ABS control module memory.
DIAGNOSIS & TESTING
Diagnose ABS using New Generation Star (NGS) Tool (49-T088-0A0) and Adapter Harness (49-F066-002).
See RETRIEVING DIAGNOSTIC TROUBLE CODES
. On all models, test ABS control module using
DVOM and adapter harness. See ABS CONTROL MODULE under COMPONENT TESTING
.
If ABS test equipment is unavailable, test each component of ABS. See COMPONENT TESTING
. If all
ABS components test okay, replace ABS control module with a known-good module and retest system.

AIR CONDITIONING SERVICING
ANTI-LOCK BRAKE SYSTEM
On models equipped with anti-lock brake systems, ALWAYS observe the following cautions:
DO NOT attempt to bleed hydraulic system without first referring to the appropriate ANTI-LOCK
BRAKE SYSTEM article in the BRAKES Section.
DO NOT mix tire sizes. As long as tires remain close to the original diameter, increasing the width is
acceptable. Rolling diameter must be identical for all 4 tires. Some manufacturers recommend tires of the
same brand, style and type. Failure to follow this precaution may cause inaccurate wheel speed readings.
Use ONLY recommended brake fluids. DO NOT use silicone brake fluids in an ABS-equipped vehicle.
BATTERY WARNING WARNING:To avoid injury from accidental air bag deployment, read and carefully
follow all warnings and service precautions. See appropriate AIR BAG
RESTRAINT SYSTEM article in ACCESSORIES/SAFETY EQUIPMENT.
CAUTION: Disconnect negative battery cable before servicing any air bag system,
steering column or passenger side dash component. After any repair, turn
ignition key to the ON position from passenger's side of vehicle in case of
accidental air bag inflation
CAUTION: Avoid breathing R-134a refrigerant and PAG lubricant vapors, exposure
may irritate eyes, nose and throat. To remove R-134a from system use R-
134a recycling equipment that meets SAE J2210 specifications. If
accidental system discharge occurs, ventilate work area before resuming
service.
WARNING:R-134a service equipment or vehicle A/C systems SHOULD NOT be
pressure tested or leak tested with compressed air. Some mixtures of
air/R134a have shown to be combustible at elevated pressures. These
mixtures are dangerous and may cause fire and/or explosions. See AIR
CONDITIONING SERVICE article in GENERAL INFORMATION section.
CAUTION: The anti-lock brake system contains electronic equipment that can be
susceptible to interference caused by improperly installed or high output
radio transmitting equipment. Since this interference could cause the
possible loss of the anti-lock braking capability, such equipment should
be installed by qualified professionals.
