C140C- TRANSFER CASE MOTOR CONTROL CIRCUIT HIGH (CONTINUED)
3.
(T316) SHIFT MOTOR CONTROL B CIRCUIT SHORTED TO VOLTAGE
Measure the voltage of the (T316) Shift Motor Control B circuit at the
Shift Motor/Mode Sensor Assembly connector.
Is there any voltage present?
Yes
>> Repair the (T316) Shift Motor Control B circuit for a short
to voltage.
Perform the TRANSFER CASE VERIFICATION TEST-
VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/TRANSFER CASE CONTROL MODULE
- DIAGNOSIS AND TESTING)
No
>> Go to 4
4.
SHIFT MOTOR CIRCUIT RESISTANCE AT FCM CONNECTOR
Turn the ignition off.
Connect the Shift Motor/Mode Sensor Assembly connector.
Measure the resistance between the (T315) Shift Motor Control A cir-
cuit and the (T316) Shift Motor Control B circuit in the FCM connector
of the IPM.
Is the resistance between 40 and 100 ohms?
Yes
>> Go to 13
No
>> Go to 5
