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 
    NOTE:

    Check for any Technical Service Bulletins (TSBs) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.

    1. Turn the ignition on.
    2. With the scan tool, record and erase TIPM DTCs.
    3. Cycle the ignition from on to off three times.
    4. Turn the ignition on.
    5. With the scan tool, read active TIPM DTCs.

      Does the scan tool display this DTC as active?

      Yes 

      • Go To  2

      No 

      • The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
  2. MEASURE VOLTAGE AT TIPM 
    1. Gain access to the Totally Integrated Power Module C3 harness connector, but do not disconnect.
    2. Backprobe and measure the voltage on both the (D55) CAN B Bus (+) and the (D54) CAN B (-) circuits.

      Does the voltage read approximately 4.65 - 4.98 volts on the (D54) CAN B Bus (-) and 0.39 - 0.46 volts on the (D55) CAN B (+) circuits?

      Yes 

      • Go To  3

      No - Voltage Between 0.3 - 0.7 of a Volt on Both Circuits 

      • Go To  9

      No - Voltage Reads 0 Volts on Either Circuit 

      • Go To  7

      No - Voltage Above 10 Volts on Either Circuit 

      • Go To  5
  3. (D55) CAN B BUS (+) CIRCUIT OPEN

    1. Turn the ignition on.
    2. With the scan tool select ECU View.
    3. Using a fused jumper wire, connect one end to ground and with the other end backprobe the (D55) CAN B Bus (+) circuit at the TIPM C3 harness connector.
      NOTE:

      This may cause some modules to no longer communicate on the Bus.

      Are some modules no longer communicating?

      Yes 

      • Using the Wiring Diagrams to further isolate the open in the circuit, repair the (D55) CAN B Bus (+) circuit for an open.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  4
  4. (D54) CAN B BUS (-) CIRCUIT OPEN 
    Fig 2: Checking CAN B Bus (+) Circuit For Open

    1. Remove the fused jumper wire.
    2. Using a fused jumper wire, connect one end to ground and with the other end backprobe the (D54) CAN B Bus (-) circuit at the TIPM C3 harness connector.
      NOTE:

      This may cause some modules to no longer communicate on the Bus.

      Are some modules no longer communicating?

      Yes 

      • Using the Wiring Diagrams to further isolate the open in the circuit, repair the (D54) CAN B Bus (-) circuit for an open.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Inspect the wiring and connectors for damage. If OK, replace and program the module that set this DTC in accordance with the Service Information.
      • Perform the appropriate verification test for the module being replaced. If there is no verification test for the associated module perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  5. (D55) CAN B BUS (+) CIRCUIT FOR A SHORT TO VOLTAGE

    1. Turn the ignition off.
    2. Disconnect the TIPM C3 harness connector.
    3. Turn the ignition on.
    4. Measure the voltage between the (D55) CAN B Bus (+) circuit and ground.

      Is the voltage above 10.0 volts?

      Yes 

      • Disconnect each CAN B Bus module one at a time while observing the voltage to determine if the short is caused by an internal short within a module. Replace the module, in accordance with the Service Information, that when disconnected eliminates the short to voltage. If the short condition is still present with all CAN B Bus modules disconnected use the Wiring Diagrams to help isolate and repair the (D55) CAN B Bus (+) circuit for a short to voltage.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  6
  6. (D54) CAN B BUS (-) CIRCUIT SHORTED TO VOLTAGE 
    Fig 4: Checking CAN B Bus (-) Circuit For Short To Voltage

    1. Measure the voltage between the (D54) CAN B Bus (-) circuit and ground.

      Is the voltage above 10.0 volts?

      Yes 

      • Disconnect each CAN B Bus module one at a time while observing the voltage to determine if the short is caused by an internal short within a module. Replace the module, in accordance with the Service Information, that when disconnected eliminates the short to voltage. If the short condition is still present with all CAN B Bus modules disconnected use the Wiring Diagrams to help isolate and repair the (D54) CAN B Bus (-) circuit for a short to voltage.
