B1D5B

B1D5B-ADJUSTABLE PEDAL SWITCH CIRCUIT PERFORMANCE





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.

Possible Causes
- CONNECTOR/TERMINAL DAMAGE
- (Q103) ADJUSTABLE PEDALS SWITCH REARWARD CIRCUIT SHORTED TO GROUND
- (Q102) ADJUSTABLE PEDALS SWITCH FORWARD CIRCUIT SHORTED TO GROUND
- (Q103) ADJUSTABLE PEDALS SWITCH REARWARD CIRCUIT AND (Q102) ADJUSTABLE PEDALS SWITCH
- FORWARD CIRCUIT SHORTED TOGETHER
- ADJUSTABLE PEDALS SWITCH - INTERNAL FAULT
- MEMORY SEAT MODULE - INTERNAL FAULT

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 DTCs.
Cycle the ignition switch from off to on.
Cycle the Adjustable Pedals Switch forward and rearward.
With the scan tool, read DTCs
Does the scan tool display: B1D5B-ADJUSTABLE PEDAL SWITCH CIRCUIT PERFORMANCE?
Yes >> Go To 2.
No >> Refer to the INTERMITTENT CONDITION diagnostic procedure. Initial Inspection and Diagnostic Overview
Perform APS VERIFICATION TEST - VER 1. APS Verification 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 - VER 1. 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 - VER 1. 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 - VER 1. 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 - VER 1. 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 - VER 1. APS Verification Test
No >> Replace the Lower Switch Bank.
Perform APS VERIFICATION TEST - VER 1. APS Verification Test
