DTC C1241





Steps 1-5





Steps 6-11





Steps 12-13

Circuit Description

The Speed dependent Steering System (Magnasteer (R)) incorporates its controller into the EBCM. The EBCM controls the amount of current supplied to the Magnasteer (R) actuator based on input from the wheel speed sensors.
Magnasteer (R) 2 also uses inputs from the wheel speed sensors along with added input from the Steering Wheel Position Sensor.

Conditions for Setting the DTC
One or both of the Magnasteer (R) actuator circuit wires become open or shorted.

Action Taken When the DTC Sets
A malfunction DTC is stored. No ABS or Car Icon (TCS indicator) indicators are turned on but Magnasteer (R) is disabled. ABS/TCS remains functional.

Conditions for Clearing the DTC
- Condition for DTC is no longer present and scan tool clear DTC function is used.
- Fifty ignition cycles have passed with no DTC(s) detected

Diagnostic Aids
- It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
- An intermittent malfunction can be caused by poor connections, broken insulation, or a wire that is broken inside the insulation.
- If an intermittent malfunction exists refer to Intermittents and Poor Connections.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. This step uses the scan tool to check the Magna Steer Feedback Current parameter.
6. This step checks for an open in the variable effort steering actuator and circuit.
