ADJUSTABLE PEDALS SENSOR
MEMORY SEAT MODULE

Diagnostic Test
1. DTC IS ACTIVE
Turn the ignition on.
With the scan tool, select view DTCs. Record all DTC information.
With the scan tool, clear stored DTCs.
Cycle the ignition switch off then on.
Move the Adjustable Pedals Switch forward and rearward several times.
With the scan tool, select view DTCs
Is the status active for this DTC?
Yes >> Go To 2
No >> Refer to the Adjustable Pedal System intermittent condition test. Initial Inspection and Diagnostic Overview

2. WIRING HARNESS CONNECTOR/TERMINALS





Turn the ignition off. Disconnect the Memory Seat Module harness connector.
Disconnect the Adjustable Pedals Sensor harness connector. Inspect the wiring harness, connectors and terminals.
Were any problems found?
Yes >> Repair as necessary. Perform APS VERIFICATION TEST - VER 1. APS Verification Test
No >> Go To 3

3. (G13) ADJUSTABLE PEDALS SENSOR SUPPLY CIRCUIT SHORT TO VOLTAGE





Turn the ignition on.
Measure the voltage of the (G13) Adjustable Pedals Sensor Supply circuit.
Is there any voltage present?
Yes >> Repair the (G13) Adjustable Pedals Sensor Supply circuit for a short to voltage. Perform APS VERIFICATION TEST - VER 1. APS Verification Test
No >> Go To 4

4. (G14) ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE





Measure the voltage of the (G14) Adjustable Pedals Sensor Signal circuit.
Is there any voltage present?
Yes >> Repair the (G14) Adjustable Pedals Sensor Signal circuit for a short to voltage. Perform APS VERIFICATION TEST - VER 1. APS Verification Test
No >> Go To 5

5. (G14) ADJUSTABLE PEDALS SENSOR SIGNAL CIRCUIT VOLTAGE





Turn the ignition off. Reconnect all connectors. Measure the voltage of the (G14) Adjustable Pedals Sensor Signal circuit in the Memory Seat Module harness connector.
Is the voltage below 4.0 volts?
Yes >> Replace and reprogram the Memory Seat Module. Perform APS VERIFICATION TEST - VER 1. APS Verification Test
No >> Replace the Adjustable Pedals Sensor. Perform APS VERIFICATION TEST - VER 1. APS Verification Test
