Circuit/System Testing
1. Ignition OFF, disconnect the harness connector C1
at the rear differential clutch control module.
2. Ignition ON, verify a test lamp does not illuminate
between the following control circuit terminals and
ground:
– Coil supply circuit terminal 5
– Low reference circuit terminal 3
➢ If the test lamp illuminates, test the appropriate
control circuit for a short to voltage.
DTC C0394
Diagnostic Instructions
• Perform the "Diagnostic System Check - Vehicle Diagnostic Information: " prior to using this diagnostic procedure.
• Review "Strategy Based Diagnosis: " for an overview of the diagnostic approach.
• "Diagnostic Procedure Instructions - Vehicle Diagnostic Information: " provides an overview of each diagnostic
category.
DTC Descriptor
DTC C0394 06: Rear Differential Temperature Sensor Circuit
Diagnostic Fault Information
Perform the "Diagnostic System Check - Vehicle Diagnostic Information: " prior to using this diagnostic procedure.
Circuit
High Clutch Temperature Sensor Circuit
Low Clutch Temperature Sensor Circuit
Circuit/System Description
The Rear Differential Clutch Control Module (CCM)
provides a power and ground circuits to the temperature
sensor. When the temperature of the module is
determined to be beyond its limits, the CCM will
temporarily disable the rear drive system.
Conditions for Running the DTC
• The ignition is ON.
• Ignition voltage is greater than 9 volts.
Conditions for Setting the DTC
An open or short to ground is detected on the
temperature sensor circuits.
Action Taken When the DTC Sets
One or more of the following actions may occur:
3. Ignition OFF, test for infinite resistance between the
following control circuit terminals and ground:
– Coil supply circuit terminal 5
– Low reference circuit terminal 3
➢ If less than the specified value, test the appropriate
control circuit for a short to ground.
4. Test for less than 5.0 ohms of resistance between
the coil supply terminal 5 and the low reference
circuit terminal 3.
➢ If greater than the specified range, test both control
circuits for an open/high resistance. If the circuits
test normal, replace the differential clutch coil.
5. If all circuits test normal, replace the CCM.
Repair Instructions
Perform the "Diagnostic Repair Verification - Vehicle
Diagnostic Information: " after completing the diagnostic
procedure.
