Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
Diagnostic Test
1.
Hydraulic Solenoid S3 Circuit For Short To Ground
Turn the ignition off.
Disconnect the Power Top Control Module C2 harness connector.
Disconnect the Hydraulic Solenoid S3 harness connector.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance between ground and the Hydraulic Solenoid
S3 Supply Voltage circuit.
Is the resistance above 100 kohms?
Yes >> Go To 2
No >> Repair the Hydraulic Solenoid S3 Supply Voltage circuit for
a short to ground.
Perform POWER TOP CONTROL MODULE VERIFICA-
TION TEST.
2.
Hydraulic Solenoid S3
With the ignition off.
Reconnect the Hydraulic Solenoid S3 harness connector.
Measure the resistance between the Hydraulic Solenoid S3 Supply
Voltage circuit and the Hydraulic Solenoid S3 Ground circuit.
Is the resistance above 3.0 ohms?
Yes >> Replace the Power Top Control Module.(Refer to 8 -
ELECTRICAL/ELECTRONIC
POWER TOP CONTROL MODULE - REMOVAL).
Perform POWER TOP CONTROL MODULE VERIFICA-
TION TEST.
No >> Replace the Power Top Hydraulic Assembly.(Refer to 23 -
BODY/CONVERTIBLE TOP/HYDRAULIC PUMP MOTOR
- REMOVAL).
Perform POWER TOP CONTROL MODULE VERIFICA-
TION TEST.
