To test the wiper motor, disconnect the windshield wiper mounting arm and pivot shaft from the
windshield wiper motor; refer to
Pivot Arm .
Disconnect the wiper motor. Connect the (1) green lead from (2) (ARBST) to the battery negative (- )
post. Connect the (3) red lead from ARBST to the wiper motor (4) common brush terminal (terminal 3).
Test the low speed mode by connecting a (5) cable from the battery positive (+) post to the (6) low
speed brush terminal (terminal 4) and measure the current draw. If the current draw is greater than 3.5
amperes, install a new windshield wiper motor.
Test the high speed mode by connecting a cable from the battery positive (+) post to the (7) high
speed brush terminal (terminal 5) and measure the current draw. If the current draw is greater than 5.5
amperes, install a new wiper motor. Klj . 19 ba

DIAGNOSIS AND TESTING
Convertible Top
Refer to Wiring Diagrams Cell
103 , for schematic and connector information.
Principles of Operation
The convertible top will only operate with the parking brake engaged and the ignition switch in the RUN
position. When the parking brake is engaged, the raise and lower relay coils are grounded through the
parking brake switch. The convertible top switch supplies power to the raise or lower relay coil when
raise or lower is selected. This power energizes the coil causing the relay contacts to close which
supplies battery power to the convertible top motor/pump assembly. The normal state of the relay is
connected to ground. When the raise or lower relay is operating, the other relay remains in its normal
state supplying the motor/pump ground.
Convertible Top Adjustments
The convertible top adjustments must be made by a qualified technician.
Inspection and Verification 1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart.

current and historical DTCs through the DLC, using a scan tool. If the air bag indicator does not
function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible
chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air
bag indicator require repair.
LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority
will be displayed. After that fault has been corrected, the next highest priority fault will be displayed.
The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the
air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag
sensors determine that deployment is required. The backup power supply will deplete its stored energy
approximately one minute after the battery ground cable is disconnected.
Electrical System
The electrical system that supports the air bag supplemental restraint system (SRS):
zis powered from the battery through the ignition circuit.
z provides the electrical path from the restraints control module (RCM) to the air bag modules.
z provides the electrical path from the RCM to the air bag indicator.
z provides the electrical path from the RCM to the data link connector (DLC).
z provides the electrical path from the RCM to the generic electronic module (GEM).
Sensor WARNING: The restraints control module (RCM) orientation is critical for proper system
operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) has been
involved in a collision in which the center tunnel area has been damaged, inspect the mounting
and bracket for deformation. If damaged, the RCM must be replaced whether or not the air bags
have deployed. In addition, make sure the area of the RCM mounting is restored to its original
condition.
The SRS contains two sensors which are integral to the RCM. The RCM is mounted on the center
tunnel under the instrument panel. Klj . 3 ba

To deplete the backup power supply energy, disconnect the battery ground cable and
wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if
equipped).
Disconnect the battery ground cable. For additional information, refer to
Section 414 - 01 .
2. Wait at least one minute for the backup power supply in the restraints control module (RCM) to deplete its stored energy.
3. WARNING: Carry a live air bag module with the air bag and trim cover pointed away
from your body. This will reduce the risk of injury in the event of an accidental
deployment.
WARNING: Do not set an air bag module down with the trim cover face down. This
will reduce the risk of injury in the event of an accidental deployment.
Remove the driver air bag module from the vehicle. Refer to Driver Air Bag Module in this
section.
4. WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and
possible violation of vehicle safety standards.
Connect a restraint system diagnostic tool to the vehicle harness at the top of the steering
column.
5. Disconnect the passenger air bag module electrical connector.
6. WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and

7. Reconnect the battery ground cable. For additional information, refer to Section 414 - 01 .
Reactivation Procedure 1. WARNING: The restraint system diagnostic tool must be removed and the air bag
modules reconnected when the system is reactivated to avoid non- deployment in a
collision, resulting in possible personal injury.

Remove the restraint system diagnostic tool from the vehicle harness connector at the
passenger air bag module.
6. Connect the passenger air bag module electrical connector.
7. Reconnect the battery ground cable. For additional information, refer to Section 414 - 01 .
8. Prove out the system.
Prove Out Procedure
Turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator
with the air bag modules or restraint system diagnostic tools installed. The air bag indicator will light
continuously for approximately six seconds and then turn off. If an air bag supplemental restraint
system (SRS) fault is present, the air bag indicator will either: zfail to light.
z remain lit continuously.
z flash.
The flashing might not occur until approximately 30 seconds after the ignition switch has been turned
from the OFF to the RUN position. This is the time required for the restraints control module (RCM) to
complete the testing of the SRS. If the air bag indicator is inoperative and an SRS fault exists, a chime
will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be
repaired before diagnosis can continue.
Glossary
Restraint System Diagnostic Tool
Restraint system diagnostic tools are used to simulate air bag module connections to the system.
Disconnect the Component
Disconnect the component means disconnect the component vehicle harness connector. It does not
mean remove the component. Do not reconnect a disconnected component unless instructed to do so. Deactivate the System Klj . 4 ba
