SCRAPPED VEHICLE
INSPECTING DEPLOYMENT TOOL
1. Connect Red deployment tool clip to battery positive terminal. Connect Black deployment tool clip to
battery negative terminal. Observe deployment tool lights. Green light should be on with Red light off.
2. Connect deployment tool connector "A" to connector "B". See Fig. 5
. Green light should be off with Red
light on. Press deployment tool activation switch. Green light should be on with Red light off.
3. If deployment tool lights function as described, it is safe to use deployment tool to activate air bag. If
deployment tool lights do not function as described, DO NOT use deployment tool. Replace deployment
tool with another unit and repeat procedure.
Driver-Side Air Bag
1. Before deploying air bag, inspect operating condition of Deployment Tool (49 H066 002). See

.
3. Connect deployment tool (49 H066 002) to clockspring connector. See Fig. 5
. Connect Red deployment
tool clip to battery positive terminal. Connect Black deployment tool clip to battery negative terminal.
Verify deployment tool Red light is on.
4. Ensure all persons are at least 20 feet from vehicle. Press deployment tool activation switch to deploy air
bag. Because of heat generated from air bag deployment, wait at least 15 minutes before handling
deplo
yed air bag module. NOTE: When scrapping vehicles with an undeployed air bag(s), air bag(s) must be
deployed inside vehicle.
NOTE: Deployment tool should always be inspected for proper operation before

BLEEDING BRAKE SYSTEM
1. Raise and support vehicle. Ensure brake fluid reservoir remains at least half full during bleeding
procedure. When bleeding brake system, start with longest brakeline first. Remove bleed screw cap.
Connect one end of transparent vinyl tube to bleed screw. Submerge other end of tube in a container half
filled with clean brake fluid.
2. Have an assistant depress brake pedal several times and hold in depressed position. Loosen bleed screw
and drain fluid into container. Tighten bleed screw.
3. Refill brake fluid reservoir if necessary. Repeat step 2) until air is no longer discharged. Tighten bleed
screw to 52-78 INCH lbs. (5.9-8.8 N.m). Ensure fluid leakage is not present. Add fluid to reservoir.
Repeat procedure for remaining wheels.
TROUBLE SHOOTING
Before attempting to diagnose vehicle, ensure ABS warning light is functioning properly. ABS warning light
will not illuminate and ABS will not operate if battery voltage is insufficient. Perform trouble shooting
procedures on ABS warning light to eliminate unnecessary repairs and/or component replacement.
ABS WARNING LIGHT DOES NOT ILLUMINATE WHEN IGNITION IS TURNED ON
1. Turn ignition on. Check if other warning lights illuminate. If other warning lights do not illuminate, check
METER fuse. Replace as necessary. If other warning lights illuminate, check for possible malfunction
and repair as necessary. Go to next step.
2. Turn ignition off. Disconnect ABS Control Module (ABS CM) connector. See COMPONENT
LOCATIONS . Turn ignition on. Check if ABS warning light illuminates. If ABS warning light
illuminates, go to next step. If ABS warning light does not illuminate, go to step 5).
3. Reconnect ABS CM connector. Turn ignition on. Check if ABS warning light illuminates. If ABS
warning light does not illuminate, go to next step. If ABS warning light illuminates, a temporary poor
contact in wiring may have occurred and ABS is now functioning properly.
4. Check if terminal AD of ABS CM harness connector is damaged or deformed. See Fig. 3
. If terminal AD
is damaged or deformed, replace wiring harness connector. If terminal AD is okay, replace ABS CM.
5. With ABS CM connector disconnected, use a jumper wire and ground terminal AD of ABS CM harness
connector. Check if ABS warning light illuminates. If ABS warning light illuminates, go to next step. If
ABS warning light does not illuminate, go to step 7).
6. With ABS CM disconnected, check continuity between terminal AB of ABS CM harness connector and
ground. Also, check continuity between terminal AC of ABS CM harness connector and ground, and CAUTION: DO NOT allow reservoir to run dry during brake bleeding procedure. If
brake fluid is spilled, clean surface immediately with alcohol, as brake
fluid will damage painted surfaces. Use only DOT 3 brake fluid and DO
NOT mix with any other types.
NOTE: Ensure brake pedal remains depressed until bleed screw is tightened.
