30075
CALIBRATION REQUIRED
B.

STEER CONTROLLER WIRING FAULT
C.

CANBUS COMMUNICATION FAULT
NOTE
Please refer to the end of this procedure for supporting diagrams.
COMPONENT OPERATIONAL CHECK
NOTE: Always check battery condition and state of charge before performing electrical troubleshooting. A faulty or low charged battery will cause electrical features to not operate as designed and give incorrect readings while performing electrical tests.
PROCEDURE OR ACTION:
1.

Conduct a visual inspection of all connectors/wiring associated with the fault code.
Are any faults detected/observed?
YES: Repair/replace connector or wiring associated with faults found. Refer to the appropriate Electrical System YRM.
NO: Proceed to Step 2.
2.

Re-key the vehicle.
Is the code still present?
YES: Proceed to Step 3.
NO: Problem may be intermittent.
3.

Locate input diagnostics (D2.30) and verify steer status (D2.30.26).
Is the steer ON?
YES: Fault may be intermittent.
NO: Proceed to Step 4.
4.

Locate output diagnostics (D3.40) and verify status line operation (D3.40.6).
Is the status line ON?
YES: Suspect short to frame.
NO: Proceed to Cause A.
CAUSE A - CALIBRATION REQUIRED
PROCEDURE OR ACTION:
1.

Calibrate the Auto Center STR (C3). For complete calibration procedures, refer to the User Interface Service Technician S/N A474N03000L=> S/N A497N030000L=> S/N D801N03000L=> S/N E826N03000L=> 2200YRM1651 manual.
Was Steer Wheel calibration successful?
YES: Clear status code and retest operation.
NO: Proceed to Cause B.
CAUSE B - STEER CONTROLLER WIRING FAULT
PROCEDURE OR ACTION:
NOTE: Key in ON position
1.

Measure voltage between the steer controller B(+) terminal and B(-).
Is voltage 24 ± 2.5 Vdc / 36 ± 3.5 Vdc?
YES: Proceed to Cause C.
NO: Inspect power and ground cables for damage and loose connections.
CAUSE C - CANBUS COMMUNICATION FAULT
PROCEDURE OR ACTION:
NOTE: Key in ON position
1.

Disconnect the steer controller connector A CPS120. Measure voltage between the steer connector CPS120, socket 14 and B(-).
Is CAN HI voltage approximately 2.5 Vdc?
YES: Proceed to Step 2.
NO: Inspect CAN HI circuit for open or short. If voltage is 0 volts, the CAN HI circuit is shorted to ground or open. If voltage is above 5 volts, the CAN HI circuit is shorted to power.
NOTE: Key in ON position.
2.

Measure voltage between the steer controller connector A CPS120, socket 6 and B(-).
Is CAN LO voltage approximately 2.5 Vdc?
YES: Disconnect battery and proceed to Step 3.
NO: Inspect CAN LO circuit for open or short. If voltage is 0 volts, the CAN LO circuit is shorted to ground or open. If voltage is above 5 volts, the CAN LO circuit is shorted to power.
3.

Measure resistance between the steer controller connector A CPS120, socket 6 and socket 14.
Is resistance 60 ± 6 ohms?
YES: No communication faults are present, connect battery and proceed to Cause B.
NO: If resistance is 120 ohms, the CANbus has an open circuit or a missing or damaged termination resistor. If resistance is 0 ohms, the CANbus circuits are shorted together.
