Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. 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. With the scan tool, record and erase DTCs.
    3. Operate the left rear window up and down several times.
    4. Wait 30 seconds.
    5. With the scan tool, read DTCs.

      Does the scan tool display B2518-LEFT REAR WINDOW POSITION SENSOR 2 CIRCUIT PERFORMANCE?

      Yes 

      • Go To  2

      No 

      • The condition that caused this symptom is currently not present. With the scan tool, check the Environmental Data to help identify the conditions in which the DTC was set. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

    1. Turn the ignition off.
    2. Disconnect the Left Rear Window Motor connector.
    3. Turn the ignition on.
    4. Measure the voltage between ground and the (Q307) Left Rear Window Hall Sensor A Signal circuit.

      Is the voltage between 4.8 and 5.3 volts?

      No 

      • Go To  4

      Yes 

      • Go To  3
  3. (Q309) LEFT REAR WINDOW HALL SENSOR B SIGNAL CIRCUIT SHORTED TO THE (Q307) LEFT REAR WINDOW HALL SENSOR A SIGNAL CIRCUIT

    1. Turn the ignition off.
    2. Disconnect the Power Top Control Module C1 connector.
    3. Measure the resistance between the (Q309) Left Rear Window Hall Sensor B Signal circuit in the PTCM C1 connector (cavity 9) and the (Q307) Left Rear Window Hall Sensor A Signal circuit in the PTCM C1 connector (cavity 7).

      Is the resistance below 10k Ohms?

      Yes 

      • Correct the crossed wiring between the (Q309) Left Rear Window Hall Sensor B Signal circuit and the (Q307) Left Rear Window Hall Sensor A Signal circuit.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Replace the power window motor in accordance with the Service Information.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

    1. Turn the ignition off.
    2. Disconnect the Power Top Control Module C1 connector.
    3. Measure the resistance between Ground and the (Q307) Left Rear Window Hall Sensor A Signal circuit.

      Is the resistance below 10k Ohms?

      Yes 

      • Repair the (Q309) Left Rear Window Hall Sensor B Signal circuit for a short to ground.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  5
  5. (Q307) LEFT REAR WINDOW HALL SENSOR A SIGNAL CIRCUIT OPEN 
    Fig 4: Checking Left Rear Window Hall Sensor A Signal Circuit For Open
    GC0123722Courtesy of CHRYSLER GROUP, LLC
    1. Measure the resistance of the (Q307) Left Rear Window Hall Sensor A Signal circuit between the PTCM C1 connector (cavity 7) and the Motor connector (cavity 5).

      Is the resistance below 2.0 Ohms?

      No 

      • Repair the (Q307) Left Rear Window Hall Sensor A Signal circuit for an open.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      Yes 

      • Go To  6
  6. (Q307) LEFT REAR WINDOW HALL SENSOR A SIGNAL CIRCUIT SHORTED TO VOLTAGE 
    Fig 5: Checking Left Rear Window Hall Sensor A Signal Circuit For Short To Voltage
    GC0123723Courtesy of CHRYSLER GROUP, LLC
    1. Turn the ignition on.
    2. Measure the voltage between Ground and the (Q307) Left Rear Window Hall Sensor A Signal circuit.

      Is there any voltage present?

      Yes 

      • Repair the (Q307) Left Rear Window Hall Sensor A Signal circuit for a short to voltage.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Replace the Power Top Control Module (PTCM) in accordance with Service Information.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
