Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

TEST FOR INTERMITTENT CONDITION
NOTE: Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.
1. Turn the ignition on.
  NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. With 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 Figure 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.
(A952) FUSED B(+) CIRCUIT OPEN OR SHORTED

1. Turn the ignition off.
2. Disconnect the TCM C2 harness connector.
3. Using a 12-volt test light connected to ground, check the (A952) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to Step 3.
  No
  - Repair the (A952) Fused B(+) circuit for an open or short.
  - Perform the CVT VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
(Z967) GROUND CIRCUIT OPEN

1. Using a 12-volt test light connected to 12-volts, check each (Z967) ground circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go to Step 4.
  No
  - Repair the (Z967) ground circuit for an open.
  - Perform the CVT VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
(D65) CAN C BUS (+) CIRCUIT OPEN

1. Turn the ignition off.
2. Disconnect the TIPM C3 harness connector.
3. Disconnect the TCM C1 harness connector.
4. Measure the resistance of the (D65) CAN C Bus (+) circuit between the TIPM C3 harness connector and the TCM C1 harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go to Step 5.
  No
  - Repair the (D65) CAN C Bus (+) circuit for an open.
  - Perform the CVT VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
(D64) CAN C BUS (-) CIRCUIT OPEN

1. Measure the resistance of the (D64) CAN C Bus (-) circuit between the TIPM C3 harness connector and the TCM C1 harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Replace and program the Transmission Control Module in accordance with the Service Information.
  - Perform the CVT VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
  No
  - Repair the (D64) CAN C Bus (-) circuit for an open.
  - Perform the CVT VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
