9810 HYDRAULIC SOLENOID S1 SUPPLY VOLTAGE CIRCUIT SHORT TO GROUND (CONTINUED) • When Monitored: With the ignition on, the Power Top Control Module (PTCM) continuously senses the • Set Condition: The PTCM senses high current flow on the Hydraulic Solenoid S1 Supply Voltage cir- Possible Causes POWER TOP HYDRAULIC ASSEMBLY HYDRAULIC SOLENOID S1 SUPPLY VOLTAGE CIRCUIT SHORT TO GROUND POWER TOP CONTROL MODULE Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Diagnostic Test 1. Hydraulic Solenoid S1 Circuit For Short To Ground Turn the ignition off. Disconnect the Power Top Control Module C2 harness connector. Disconnect the Hydraulic Solenoid S1 harness connector. Note: Check connectors — Clean/repair as necessary. Is the resistance above 100 kohms? Yes >> Go To 2 No >> Repair the Hydraulic Solenoid S1 Supply Voltage circuit for a short to ground. Perform POWER TOP CONTROL MODULE VERIFICA- 2. Hydraulic Solenoid S1 With the ignition off. Reconnect the Hydraulic Solenoid S1 harness connector. Measure the resistance between the Hydraulic Solenoid S1 Supply Is the resistance above 3.0 ohms? Yes >> Replace the Power Top Control Module.(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/ POWER TOP CONTROL MODULE - REMOVAL). Perform POWER TOP CONTROL MODULE VERIFICA- No >> Replace the Power Top Hydraulic Assembly.(Refer to 23 - BODY/CONVERTIBLE TOP/HYDRAULIC PUMP MOTOR Perform POWER TOP CONTROL MODULE VERIFICA- ZH CONVERTIBLE TOP 23 - 115 |
