INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.
Look for the data to change or for the DTC to reset during the wiggle test.
Were any problems found?
Yes
>> Repair as necessary.
Perform the TRANSFER CASE VERIFICATION TEST-VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/TRANSFER CASE CONTROL MODULE - DIAGNOSIS AND TESTING)
No
>> Test complete.

Diagnostic Test
1.
DTC IS ACTIVE
Ignition on, engine not running.
With the scan tool, select View DTCs.
Is the status Active for this DTC?
Yes
>> Go to 2
No
>> Go to 16
2.
SHIFT MOTOR CIRCUIT RESISTANCE
Turn the ignition off.
Remove the Front Control Module (FCM) from the Integrated Power
Module (IPM).
Measure the resistance between the (T315) Shift Motor Control A cir-
cuit and the (T316) Shift Motor Control B circuit at the FCM connector
in the IPM.
Is the resistance between 40 and 100 ohms?
Yes
>> Go to 15
No
>> Go to 3

3.
(T315) SHIFT MOTOR CONTROL A CIRCUIT OPEN
Disconnect the Shift Motor/Mode Sensor Assembly harness connector.
Measure the resistance of the (T315) Shift Motor Control A circuit from
the Shift Motor/Mode Sensor Assembly harness connector to the FCM
connector in the IPM.
Is the resistance above 5.0 ohms?
Yes
>> Go to 4
No
>> Go to 5
4.
(T315) SHIFT MOTOR CONTROL A CIRCUIT OPEN (IPM)
Disconnect the Integrated Power Module C5 harness connector.
Measure the resistance of the (T315) Shift Motor Control A circuit from
the Shift Motor/Mode Sensor Assembly harness connector to the Inte-
grated Power Module C5 harness connector.
Is the resistance above 5.0 ohms?
Yes
>> Repair the (T315) Shift Motor Control A circuit for an open.
Perform the TRANSFER CASE VERIFICATION TEST-
VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/TRANSFER CASE CONTROL MODULE
- DIAGNOSIS AND TESTING)
