Failure to follow the procedures exactly as written may result in serious injury or death.
1. Ignition OFF, disconnect the 42V harness connector X2 at the APM.
2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 3 ohms between the ground
circuit terminal 1 X2 of the APM and ground.
锟斤拷If greater than the specified range, test the APM ground circuits for an open/high resistance. If the circuits test normal, replace the APM.
3. Ignition OFF, connect a DMM between the 42V+ circuit terminal 2 X2 of the APM and ground.
4. Ignition ON, command the APM Intermediate Voltage Control ON with a scan tool. Test for 37.5-60 volts between the 42V+ circuit terminal
2 X2 terminal and ground. Command the APM Intermediate Voltage Control OFF after completing this test.
锟斤拷If not within the specified range, replace the APM.
5. Ignition OFF, verify that the 42V harness connector X2 is connected under the PSCM.
锟斤拷If the connector is not connected, connect the connector.
6. If all circuits test normal, replace the PSCM.
Low Voltage When Turning
1. Inspect the steering system for mechanical binding. The steering should have a heavy feel, if the power steering is disabled, but should not
bind.
锟斤拷If there is any mechanical binding in the steering system, refer to Steering Effort Hard in One or Both Directions (Standard) (See:
Steering and Suspension/Steering/Testing and Inspection/Symptom Related Diagnostic Procedures/Steering Effort Hard in One or Both
Directions (Standard))Steering Effort Hard in One or Both Directions (HP2) ().
2. If all circuits test normal, replace the power steering motor.
Repair Instructions

DTC C0896
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System
Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an
overview of the diagnostic approach.
* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure
Instructions) provides an overview of each diagnostic category.
DTC Descriptors
DTC C0896 03
- Device Voltage Range Below Threshold
DTC C0896 07
- Device Voltage Range Above Threshold
Circuit/System Description
The transfer case shift control module (TCCM) monitors the battery voltage feed to the TCCM. This DTC detects if the battery voltage is out of
range. This could indicate a vehicle wide issue in which all electrical components would be affected, or it could be TCCM specific due to poor
power or ground connections.
