DTC Descriptor
DTC C0896 00
- Device Voltage Range Performance




Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.






Circuit/System Description

The power steering control module (PSCM) has a discrete battery positive voltage supply circuit. The PSCM monitors the voltage level on this circuit to ensure the power steering system has adequate voltage levels to perform the system functions.


Conditions for Running the DTC

Ignition ON, Engine ON


Conditions for Setting the DTC

Power steering system voltage is 9-10 volts for at least one second.


Action Taken When the DTC Sets

* DTC C0896 00 is stored in memory.
* Steering assist is slightly reduced.



Conditions for Clearing the DTC

* A current DTC will clear when power steering system voltage is greater than 10 volts for more than one second.
* A history DTC will clear after 100 consecutive ignition cycles with the power steering voltage greater than 10 volts.



Diagnostic Aids

* Inspect the 80-amp EPS fuse of the underhood fuse block for an open.
* Inspect for poor connections at the underhood fuse block stud ring terminal.
* Inspect for poor connections at ground terminal G103 of the PSCM.
* Inspect for poor connections at the PSCM.

Scan Tool Reference

Diagnostic System Check - Vehicle for PSCM scan tool information


Circuit/System Verification

Ignition ON, Engine OFF, observe the scan tool Battery Voltage parameter in the Power Steering Control Module Data List. The specified value should be greater than 10 volts. If not greater than the specified value, check for an electrical intermittent. Refer to Testing for Intermittent Conditions and Poor Connections .


Circuit/System Testing

1. Ignition OFF, disconnect the ground harness connector at the PSCM.
2. Test for less than 1.0 ohm between the ground circuit Connector X1 terminal A and ground.

• If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, test or replace the power steering assist motor.

3. Verify that a test lamp illuminates between the B+ circuit Connector X1 terminal B and ground.

• If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

4. Ignition ON, verify that a test lamp illuminates between the ignition circuit Connector X2 terminal 8 and ground.

• If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.

5. If all circuits test normal, replace the PSCM.



Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
