For a complete wiring diagram Diagrams/Electrical. Electrical Diagrams


- When Monitored:

The Adjustable Pedals Switch is in active operation.

- Set Condition:

The Memory Seat Module detects an activation of both pedal switches at the same time.








Diagnostic Test


1. CHECK FOR DTC B1D5B-ADJUSTABLE PEDAL SWITCH CIRCUIT PERFORMANCE

NOTE: This DTC must be active for the results of this test to be valid.

Turn the ignition on.

With the scan tool, record and erase DTC's.

Cycle the ignition switch from off to on.

Cycle the Adjustable Pedals Switch forward and rearward.

With the scan tool, read DTC's

Does the scan tool display: B1D5B-ADJUSTABLE PEDAL SWITCH CIRCUIT PERFORMANCE?

Yes

- Go To 2

No

- Refer to the APS-INTERMITTENT CONDITION TEST. ABS Intermittent Condition Test



2. CHECK CONNECTOR/TERMINAL FOR DAMAGE


NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.

Turn the ignition off.

Inspect the Memory Seat Module harness connector and Lower Switch Bank harness connector.

Is the Lower Switch Bank or any of the connectors/terminals damaged?

Yes

- Repair as necessary.
- Perform APS VERIFICATION TEST. APS Verification Test

No

- Go To 3



3. CHECK (Q103) ADJUSTABLE PEDALS SWITCH REARWARD CIRCUIT FOR A SHORT TO GROUND





Disconnect the Memory Seat Module harness connector.

Disconnect the Lower Switch Bank harness connector.

Using a 12-volt test light connected to 12-volts, probe the (Q103) Adjustable Pedals Switch Rearward circuit.

Does the test light illuminate brightly?

Yes

- Repair the (Q103) Adjustable Pedals Switch Rearward circuit for a short to ground.
- Perform APS VERIFICATION TEST. APS Verification Test

No

- Go To 4



4. CHECK (Q102) ADJUSTABLE PEDALS SWITCH FORWARD CIRCUIT FOR A SHORT TO GROUND

Using a 12-volt test light connected to 12-volts, probe the (Q102) Adjustable Pedals Switch Forward circuit.

Does the test light illuminate brightly?

Yes

- Repair the (Q102) Adjustable Pedals Switch Forward circuit for a short to ground.
- Perform APS VERIFICATION TEST. APS Verification Test

No

- Go To 5



5. CHECK (Q103) ADJUSTABLE PEDALS SWITCH REARWARD CIRCUIT AND ADJUSTABLE PEDALS SWITCH FORWARD CIRCUIT FOR A SHORT TOGETHER





Measure the resistance between the (Q103) Adjustable Pedals Switch Rearward circuit and (Q102) Adjustable Pedals Switch Forward circuit.

Is the resistance above 5.0 ohms?

Yes

- Go To 6

No

- Repair the (Q103) Adjustable Pedals Switch Rearward circuit and (Q102) Adjustable Pedals Switch Forward circuit for a short together.
- Perform APS VERIFICATION TEST. APS Verification Test



6. CHECK LOWER SWITCH BANK SHORTED





Measure the resistance between the (Q103) Adjustable Pedals Switch Rearward and (Q102) Adjustable Pedals Switch Forward terminals at the Lower Switch Bank.

Is the resistance below 5.0 ohms?

Yes

- Replace and reprogram the Memory Seat Module.
- Perform APS VERIFICATION TEST. APS Verification Test

No

- Replace the Lower Switch Bank.
- Perform APS VERIFICATION TEST. APS Verification Test
