Dodge Durango (HB). Manual — part 1341
C1402- TRANSFER CASE RANGE SELECT SWITCH CIRCUIT HIGH (CONTINUED)
6.
TRANSFER CASE SELECTOR SWITCH (Z973) GROUND CIRCUIT OPEN
Measure the resistance of the Transfer Case Selector Switch (Z973)
ground circuit.
Is the resistance above 5.0 ohms?
Yes
>> Repair the Transfer Case Selector Switch (Z973) ground
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)
No
>> Go To 7
7.
INSTRUMENT CLUSTER
Repair
Replace the Instrument Cluster in accordance with the Service Information.

Is the voltage below 0.2 volts?
Yes
>> Go to 2
No
>> Go to 8
2.
(T103) 5 VOLT SUPPLY CIRCUIT VOLTAGE BELOW 0.2 VOLTS
Turn the ignition off.
Disconnect the Shift Motor/Mode Sensor connector.
Turn the ignition on.
Measure the voltage of the (T103) 5 Volt Supply circuit.
Is the voltage below 0.2 volts?
Yes
>> Go to 3
No
>> Go to 5
