Diagnostic Routine C

Diagnostic Overview

The Adjustable Pedals Only Move in 1-Second Intervals

Refer to Wiring Diagram Set 127 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

The SCCM (Steering Column Control Module) uses a Hall-effect sensor integral to the motor to identify the current pedal position. The SCCM (Steering Column Control Module) sends a reference voltage along the sensor feed circuit, through the Hall-effect sensor and back to the SCCM (Steering Column Control Module) along the signal return circuit.

When the following DTCs (Diagnostic Trouble Codes) are set, the adjustable pedals enter a "jog mode". When the pedals are in jog mode, the memory system recall will not function from either the memory SET switch or the RKE (Remote Keyless Entry) feature. When the pedals are activated using the adjustable pedal switch, the motor will move the pedals for one second regardless of the length of time the button is actually pressed.

DTC Fault Trigger Conditions

Pinpoint Test

1. CHECK THE SCCM (Steering Column Control Module) DTCs (Diagnostic Trouble Codes)

1. Using a scan tool, perform SCCM (Steering Column Control Module) self-test.

Were DTCs (Diagnostic Trouble Codes) B1368:11 or B1368:12 retrieved?

2. CHECK THE SCCM (Steering Column Control Module) HALL-EFFECT CIRCUITS FOR A SHORT TO VOLTAGE

1. Ignition OFF.

2. Disconnect Adjustable Pedal Motor.

3. Disconnect SCCM (Steering Column Control Module) C2414C.

4. Ignition ON.

5. Measure:

Is any voltage present?

3. CHECK THE SCCM (Steering Column Control Module) HALL-EFFECT CIRCUITS FOR A SHORT TO GROUND

1. Ignition OFF.

2. Measure:

Are the resistances greater than 10,000 ohms?

4. CHECK THE SCCM (Steering Column Control Module) HALL-EFFECT CIRCUITS FOR AN OPEN

1. Measure:

Are the resistances less than 3 ohms?

5. CHECK THE SCCM (Steering Column Control Module) HALL-EFFECT CIRCUITS FOR A SHORT TOGETHER

1. Measure:

Is the resistance greater than 10,000 ohms?
