B1D5B-ADJUSTABLE PEDAL SWITCH CIRCUIT PERFORMANCE





For a complete wiring diagram, refer to the Wiring Information.

- 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.





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.

1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Cycle the ignition switch from off to on.
4. Cycle the Adjustable Pedals Switch forward and rearward.
5. With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
- Refer to the APS INTERMITTENT CONDITION TEST. Testing and Inspection

2. CHECK CONNECTOR/TERMINAL FOR DAMAGE

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

1. Turn the ignition off.
2. Inspect the Memory Seat Module C5 harness connector and Adjustable Pedal Switch harness connector.

Is the Adjustable Pedals Switch or any of the connectors/terminals damaged?

Yes

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

No

- Go To 3

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




1. Turn the ignition off.
2. Disconnect the Memory Seat Module harness C5 connector.
3. Disconnect the Adjustable Pedals Switch harness connector.
4. Using a 12-volt test light connected to 12-volts, probe the (Q103) Adjustable Pedals Switch Rearward circuit at the Adjustable Pedals Switch harness connector.

Does the test light illuminate brightly?

Yes

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

No

- Go To 4

4. CHECK (Q102) ADJUSTABLE PEDALS SWITCH FORWARD CIRCUIT FOR A SHORT TO GROUND
1. Using a 12-volt test light connected to 12-volts, probe the (Q102) Adjustable Pedals Switch Forward circuit at the Adjustable Pedals Switch harness connector.

Does the test light illuminate brightly?

Yes

- Repair the (Q102) Adjustable Pedals Switch Forward circuit for a short to ground.
- Perform the 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




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

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 the APS VERIFICATION TEST. APS Verification Test

6. CHECK ADJUSTABLE PEDALS SWITCH SHORTED




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

Is the resistance below 5.0 ohms?

Yes

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

No

- Replace the Adjustable Pedals Switch.
- Perform the APS VERIFICATION TEST. APS Verification Test
