9840 HYDRAULIC SOLENOID S4 SUPPLY VOLTAGE CIRCUIT SHORT TO GROUND

9840 Hydraulic Solenoid S4 Supply Voltage Circuit Short To Ground:

WHEN MONITORED
With the ignition on, the Power Top Control Module (PTCM) continuously senses the voltage on the Hydraulic Solenoid S4 Supply Voltage circuit.

SET CONDITION
The PTCM senses high current flow on the Hydraulic Solenoid S4 Supply Voltage circuit.

POSSIBLE CAUSES
- Power top hydraulic assembly
- Hydraulic solenoid S4 supply voltage circuit short to ground
- Power top control module

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

DIAGNOSTIC TEST

1. Hydraulic Solenoid S4 Circuit For Short To Ground




Turn the ignition off.
Disconnect the Power Top Control Module C2 harness connector.
Disconnect the Hydraulic Solenoid S4 harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance between ground and the Hydraulic Solenoid S4 Supply Voltage circuit.

Q: Is the resistance above 100 kohms?

YES: Go To 2
NO: Repair the Hydraulic Solenoid S4 Supply Voltage circuit for a short to ground. Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test

2. Hydraulic Solenoid S4




With the ignition off.
Reconnect the Power Top Control Module C2 harness connector.
Measure the resistance between the Hydraulic Solenoid S4 Supply Voltage circuit and the Hydraulic Solenoid S4 Ground circuit.

Q: Is the resistance above 3.0 ohms?

YES: Replace the Power Top Control Module. Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test
NO: Replace the Power Top Hydraulic Assembly. Perform POWER TOP CONTROL MODULE VERIFICATION TEST. Power Top Verification Test
