Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. TEST FOR INTERMITTENT CONDITION 
    1. Turn the ignition on.
    2. Using a scan tool, record and erase Diagnostic Trouble Codes (DTCs).
    3. Cycle the ignition from on to off.
    4. Turn the ignition on.
    5. Operate the Adjustable Pedals switch in both directions then wait 5 seconds.
    6. With the scan tool, read DTCs.

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

      Yes 

      • Go To  2.

      No 

      • The conditions that caused this code to set are not present at this time. Perform the APS INTERMITTENT CONDITION TEST. Refer to Standard Procedure .
  2. CHECK THE (Q102)/(Q103) ADJUSTABLE PEDALS SWITCH FORWARD/REARWARD CIRCUITS FOR A SHORT TOGETHER, TO GROUND, OR TO (Z910) GROUND CIRCUIT 
    1. Turn the ignition off.
    2. Disconnect the MSM C5 harness connector.
    3. Disconnect the Adjustable Pedals switch harness connector.
      NOTE:

      Check connectors. Clean and repair as necessary.

    4. 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.
    5. Measure the resistance of the (Q102) Adjustable Pedals Switch Forward circuit between ground and the Adjustable Pedals switch harness connector.
    6. Measure the resistance of the (Q103) Adjustable Pedals Switch Rearward circuit between ground and the Adjustable Pedals switch harness connector.
    7. Measure the resistance between the (Q102) Adjustable Pedals Switch Forward circuit and the (Z910) Ground circuit at the Adjustable Pedals switch harness connector.
    8. Measure the resistance between the (Q103) Adjustable Pedals Switch Rearward circuit and the (Z910) Ground circuit at the Adjustable Pedals switch harness connector.

      Is the resistance below 10K Ohms for any measurement?

      Yes 

      • Repair all circuits with a resistance below 10K Ohms for a short to one another/to ground or (Z910) Ground circuit.
      • Perform the APS VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  3.
  3. CHECK FOR A SHORTED ADJUSTABLE PEDALS SWITCH 
    1. Remove the Adjustable Pedals Switch in accordance with the Service Information.
    2. 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.
    3. Measure the resistance between the (Q102) Adjustable Pedals Switch Forward circuit and the (Z910) Ground circuit at the Adjustable Pedals Switch (component) connector.
    4. Measure the resistance between the (Q103) Adjustable Pedals Switch Rearward circuit and the (Z910) Ground circuit at the Adjustable Pedals Switch (component) connector.

      Is the resistance below 10K Ohms for any measurement?

      Yes 

      • Replace the Adjustable Pedals Switch in accordance with the Service Information.
      • Perform the APS VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Replace the Memory Seat Module (MSM) in accordance with the Service Information.
      • Perform the APS VERIFICATION TEST. Refer to Standard Procedure .
