B1D5B
B1D5B-00-Adjustable Pedal Switch Circuit Performance
For a complete wiring diagram, refer to.
• When Monitored: The Adjustable Pedals Switch is in active operation.
• Set Condition: The Memory Seat Module receives a conflicting input from the Adjustable Pedals Switch following an Adjustable Pedals Switch activation.
Test Step 1 - TEST FOR INTERMITTENT CONDITION
• Ignition on, engine not running.
• Using a scan tool, record and erase DTCs.
• Cycle the ignition switch from off to on.
• Cycle the Adjustable Pedals Switch forward and rearward, then wait five seconds.
• With the scan tool, read DTCs.
Does the scan tool display: DTC B1D5B-00-ADJUSTABLE PEDAL SWITCH CIRCUIT PERFORMANCE?
Yes
• Go to Test Step 2 => [ Test Step 2 - CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD
CIRCUITS FOR A SHORT TOGETHER ]
No
• Perform the APS Intermittent Condition Test. Refer to => Non-DTC Based Diagnostics. APS Intermittent Condition Test
Test Step 2 - CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD CIRCUITS FOR A SHORT TOGETHER
• Turn the ignition off to the lock position.
• Disconnect the Memory Seat Module C5 harness connector.
• Disconnect the Adjustable Pedals Switch harness connector.
• Check connectors. Clean and repair as necessary.
• Measure the resistance between the (Q102) Adjustable Pedals Switch Forward circuit and the (Q103) Adjustable Pedals Switch Rearward circuit at the Adjustable Pedals Switch harness connector.
Is the resistance below 10K Ohms?
Yes
• Repair the (Q102) Adjustable Pedals Switch Forward circuit for a short to (Q103) Adjustable Pedals Switch Rearward circuit.
• Perform the APS Verification Test. Refer to => Non-DTC Based Diagnostics. APS Verification Test
No
• Go to Test Step 3 => [ Test Step 3 - CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD
CIRCUITS FOR A SHORT TO GROUND ]
Test Step 3 - CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD CIRCUITS FOR A SHORT TO GROUND
• Measure the resistance of the (Q102) Adjustable Pedals Switch Forward circuit between ground and the Adjustable Pedals Switch harness connector.
• Measure the resistance of the (Q103) Adjustable Pedals Switch Rearward circuit between ground and the Adjustable Pedals Switch harness connector.
Is the resistance below 10K Ohms for any measurement?
Yes
• Repair the short to ground in the (Q102) Adjustable Pedals Switch Forward circuit or (Q103) Adjustable Pedals Switch Rearward circuit.
• Perform the APS Verification Test. Refer to => Non-DTC Based Diagnostics. APS Verification Test
No
• Go to Test Step 4 => [ Test Step 4 - CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD
CIRCUITS FOR A SHORT TO (Z905) GROUND CIRCUIT ]
Test Step 4 - CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD CIRCUITS FOR A SHORT TO (Z905) GROUND CIRCUIT
• Measure the resistance between the (Q102) Adjustable Pedals Switch Forward circuit and the (Z905) Ground circuit at the Adjustable Pedals Switch harness connector.
• Measure the resistance between the (Q103) Adjustable Pedals Switch Rearward circuit and the (Z905) Ground circuit at the Adjustable Pedals Switch harness connector.
Is the resistance below 10K Ohms for any measurement?
Yes
• Repair the short between the (Q102) Adjustable Pedals Switch Forward circuit or (Q103) Adjustable Pedals Switch Rearward circuit and the (Z905) Ground circuit.
• Perform the APS Verification Test. Refer to => Non-DTC Based Diagnostics. APS Verification Test
No
• Go to Test Step 5 => [ Test Step 5 - CHECK FOR A SHORTED ADJUSTABLE PEDALS SWITCH ]
Test Step 5 - CHECK FOR A SHORTED ADJUSTABLE PEDALS SWITCH
• Measure the resistance between the (Q102) Adjustable Pedals Switch Forward circuit and the (Q103) Adjustable Pedals Switch Rearward circuit at the Adjustable Pedals Switch component connector.
• Measure the resistance between the (Q102) Adjustable Pedals Switch Forward circuit and the (Z905) Ground circuit at the Adjustable Pedals Switch component connector.
• Measure the resistance between the (Q103) Adjustable Pedals Switch Rearward circuit and the (Z905) Ground circuit at the Adjustable Pedals Switch component connector.
Is the resistance below 10K Ohms for any measurement?
Yes
• Replace the Adjustable Pedals Switch.
• Perform the APS Verification Test. Refer to => Non-DTC Based Diagnostics. APS Verification Test
No
• Replace the Memory Seat Module.
• Perform the APS Verification Test. Refer to => Non-DTC Based Diagnostics. APS Verification Test
