C0362

DTC C0362





Test 1-8

Circuit Description
The 4WD low signal circuit is used to notify the Powertrain Control Module (PCM) that the vehicle is in 4WD low range. The PCM supplies 12 V to this circuit. The transfer case shift control module grounds this circuit when the vehicle is in 4WD low range.
This DTC detects a transfer case shift control module problem, or a short to voltage on the 4WD low signal circuit.

Conditions for Setting the DTC
^ After the transfer case shift control module grounds the 4WD low signal circuit and reads back a high voltage, the DTC is set. The system will not attempt again during that ignition cycle.
^ The transfer case shift control module reads back a high voltage when a low voltage is expected on the 4 low signal circuit. Action Taken When the DTC Sets
^ The transmission shift point may be affected.
^ The SERVICE 4WD indicator lamp will be latched on for the remainder of the current ignition cycle.

Conditions for Clearing the DTC
^ The transfer case shift control module will clear the DTC if the condition for setting the DTC no longer exits.
^ A history DTC will clear after 100 consecutive ignition cycles without a fault present.
^ History DTCs can be cleared using a scan tool.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. This step tests the 4WD low signal circuit for voltage.
3. This step tests the 4WD low signal circuit for a short to voltage.
4. This step tests the 4WD low signal circuit for an open or high resistance.
5. This step repairs the 4WD low signal circuit for a short to voltage.
