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

      Does the scan tool display this DTC as active?

      Yes 

      • Go to step  2

      No 

      • Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
  2. MEASURE VOLTAGE AT TIPM 
    1. Gain access to the Totally Integrated Power Module C5 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 of a volt on the (D55) CAN B (+) circuits?

      Yes 

      • Go to step  3

      No - Voltage between 0.3 - 0.7 of a volt on both circuits 

      • Go to step  9

      No - Voltage reads 0 volts on either circuit 

      • Go to step  7

      No - Voltage above 10 volts on either circuit 

      • Go to step  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 (D54) CAN B Bus (-) circuit at the TIPM C5 harness connector.
      NOTE: A red "X" will appear next to modules that can no longer communicate on the Bus.

      Did a red "X" appear next to any modules on the scan tool?

      Yes 

      No 

      • Go to step  4
  4. (D54) CAN B BUS (-) CIRCUIT OPEN

    1. With the scan tool select ECU View.
    2. 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 C5 harness connector.
      NOTE: A red "X" will appear next to modules that can no longer communicate on the Bus.

      Did a red "X" appear next to any modules on the scan tool?

      Yes 

      No 

  5. CHECK THE (D55) CAN B BUS (+) CIRCUIT FOR A SHORT TO VOLTAGE

    1. Turn the ignition off.
    2. Disconnect the Totally Integrated Power Module C5 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 appropriate verification test for the module being replaced. If there is no verification test for the associated module perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

      No 

      • Go to step  6
  6. CHECK THE (D54) CAN B BUS (-) CIRCUIT FOR A 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.

      No 

  7. CHECK THE (D55) CAN B BUS (+) CIRCUIT FOR A SHORT TO GROUND

    1. Turn the ignition off.
    2. Disconnect the Totally Integrated Power Module C5 harness connector.
    3. Measure the resistance between ground and the (D55) CAN B Bus (+) circuit.

      Is the resistance above 1, 000.0 Ohms?

      Yes 

      • Go to step  8

      No 

      • Disconnect each CAN B Bus module one at a time while observing the resistance 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 ground.

      Yes 

      • Disconnect each CAN B Bus module one at a time while observing the resistance 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 between the two circuits.
