Diagnostic Test

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
  NOTE: Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. Using the scan tool, select ECU View.
  NOTE: A red "X" will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.
  
  NOTE: Check the TIPM for any active CAN C hardware DTCs, perform DTC before proceeding.
  
  Does the scan tool display a red "X" next to the module?
  
  Yes
  - Go to step 2
  No
  - The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched and partially broken wires and the wiring harness connectors for broken, bent, pushed out and corroded terminals.
(A925) FUSED B(+) CIRCUIT OPEN OR SHORTED

1. Turn the ignition off.
2. Disconnect the DTCM harness connector.
3. Using a 12-volt test light connected to ground, check the (A925) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 3
  No
  - Repair the (A925) Fused B(+) circuit for an open or short.
  - Perform DTCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Drivetrain Control (DTCM) - Standard Procedure .
(Z902) GROUND CIRCUIT OPEN

1. Using a 12-volt test light connected to 12-volts, check the (Z902) ground circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 4
  No
  - Repair the (Z902) ground circuit for an open.
  - Perform DTCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Drivetrain Control (DTCM) - Standard Procedure .
(F214) FUSED RUN RELAY OUTPUT CIRCUIT OPEN OR SHORTED

1. Turn the ignition on.
2. Using a 12-volt test light connected to ground, check the (F214) Fused Run Relay Output circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 5
  No
  - Repair the (F214) Fused Run Relay Output circuit for an open or short.
  - Perform DTCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Drivetrain Control (DTCM) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the TIPM C6 harness connector.
3. Measure the resistance of the (D65) CAN C Bus (+) circuit between the TIPM C6 harness connector and the DTCM harness connector.
  Is resistance below 5.0 Ohms?
  
  Yes
  - Go to step 6
  No
  - Repair the (D65) CAN C Bus (+) circuit for an open.
  - Perform DTCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Drivetrain Control (DTCM) - Standard Procedure
(D64) CAN C BUS (-) CIRCUIT OPEN

1. Measure the resistance of the (D64) CAN C Bus (-) circuit between the TIPM C6 harness connector and the DTCM harness connector.
  Is resistance below 5.0 Ohms?
  
  Yes
  - Replace and program the Drive Train Control Module in accordance with the Service Information.
  - Perform DTCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Drivetrain Control (DTCM) - Standard Procedure .
  No
  - Repair the (D64) CAN C Bus (-) circuit for an open.
  - Perform DTCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Drivetrain Control (DTCM) - Standard Procedure .
