Symptoms - Adjustable Pedals

1. Perform the «Diagnostic System Check - Vehicle»(ref-644698-S03753758692014072300000) before using the symptom table in order to verify that all of the following are true: There are no DTCs set. The control modules can communicate via the serial data link.
2. Review the system operation in order to familiarize yourself with the system functions. Refer to «Adjustable Pedals Description and Operation»(ref-644743-S35702264142014072300000) .

Intermittent

Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections .

Scan Tool Reference

Control Module References for scan tool information

1. Verify DTC B3604, B3605, B3606, or B3607 is not set. If any of the DTCs are set, refer to «Diagnostic Trouble Code (DTC) List - Vehicle»(ref-644698-S15398667192014072300000) .
2. Ignition ON, observe the scan tool Adjustable Pedals Control Switch and Adjustable Pedal Direction Command parameters while cycling the adjustable pedal switch between the FWD and RWD position. The appropriate parameter should change between Active and Inactive as commanded. If the parameters do not change between the specified values, refer to «Adjustable Pedal Switch Circuit Malfunction»(ref-644743-S42363711362014072300000) .
3. Verify the scan tool Adjustable Pedals Horizontal Position parameter is between 0.45-4.55 V. If not within the specified range, refer to «Adjustable Pedal Position Sensor Circuit Malfunction»(ref-644743-S42363711362014072300000) .
4. Command the adjustable pedals to move forward and rearward. The pedals should move in the commanded direction. If the pedals do not move in the commanded direction, refer to «Adjustable Pedal Motor Circuit Malfunction»(ref-644743-S42363711362014072300000) .

Perform Diagnostic Repair Verification after completing the repair.

The memory seat module monitors the locations of both pedal assemblies in order to prevent a step over condition from occurring. Any time adjustable pedal system components are replaced, such as a memory seat module or pedal position sensors, the system must be calibrated. The calibration procedure allows the memory seat module to store the position sensor value through the full range of pedal travel.

1. Install a scan tool.
2. Go to the Memory Seat Module, Special Functions menu.
3. Using the scan tool Output Controls operate the pedals to the full forward position.
4. Start the calibration procedure and allow the memory seat module to operate the pedals to the rearward stop and return to the forward stop without activating any switch inputs.

Adjustable Pedals System Components

The adjustable pedals system consists of the following components

1. The adjustable pedals switch
2. The memory seat control module
3. The adjustable pedals assembly
4. The adjustable pedal position sensor
