B1C35 Possible Symptoms


Engine Light ON (or Service Engine Soon Warning Light)


B1C35 Possible Causes


Faulty Steering Column Telescope Motor,Steering Column Telescope Motor harness is open or shorted,Steering Column Telescope Motor circuit poor electrical connection,Faulty Steering Column Control Module (SCCM)


B1C35 Description


The Steering Column Control Module (SCCM) monitors the position of the adjustable steering column using of Hall-effect type rotation sensors that are integral to the tilt and telescoping motors. Both the adjustable steering column tilt motor and telescope motor can be serviced separately from the steering column. The SCCM sends a reference voltage along the sensor feed circuit through the Hall-effect sensor and back to the SCCM through a shared signal return circuit. The sensors provide a digital signal used by the SCCM to calculate the position of the steering column in relation to the full forward/rearward and full up/down positions. The SCCM uses this signal to store and recall memory positions, to carry out the easy entry/exit operations and to make sure the adjustable steering column tilt and telescope motors do not stall against the steering column end of travel. If an adjustable steering column tilt or telescope motor sensor Diagnostic Trouble Code (DTC) sets (or if either of the sensor circuits become open), the SCCM does not recall a programmed memory position or automatically position the steering column during the easy entry/exit operations. The affected steering column motor operates in jog mode. Jog mode allows limited operation of the affected steering column motor using only the steering column control switch. When the steering column control switch is operated in jog mode, the steering column moves in the desired direction for one second, then stops regardless of the length of time the switch is actually activated. The steering column control switch must be released, then activated again in order to move the steering column for an additional second.
