Diagnostic Test

WARNING: This page is about a different car, the 2008 Chrysler Pacifica. 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.

Turn the ignition on.

NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

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.

Does the scan tool display a red X next to the module?

Yes
1. Go To step 2.
No
1. 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.
(Z100) (Z10) GROUND CIRCUIT OPEN

Turn the ignition off.

Using a 12-volt test light connected to 12-volts, probe each (Z100) and (Z10) ground circuit.

Does the test light illuminate brightly for each circuit?

Yes
1. Go To step 3.
No
1. Repair the (Z100) or (Z10) ground circuit for an open.
2. Perform BODY VER TEST - VER 1 .
(A101) FUSED B(+) CIRCUIT OPEN

Using a 12-volt test light connected to ground, probe the (A101) Fused B(+) circuit.

Does the test light illuminate brightly?

Yes
1. Go To step 4.
No
1. Repair the (A101) Fused B(+) circuit for an open.
2. Perform BODY VER TEST - VER 1 .
(F20) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN

Turn the ignition on.

Using a 12-volt test light connected to ground, probe the (F20) Fused Ignition Switch Output (Run-Start) circuit.

Does the test light illuminate brightly?

Yes
1. Go To step 5.
No
1. Repair the (F20) Fused Ignition Switch Output (Run-Start) circuit for an open.
2. Perform BODY VER TEST - VER 1 .
(D72) DIAGNOSTIC CAN C (+) CIRCUIT OPEN

Turn the ignition off.

Disconnect the BCM C4 harness connector.

Disconnect the scan tool from the DLC.

NOTE: Check the connectors at both the DLC and the BCM.

Measure the resistance of the (D72) Diagnostic CAN C (+) circuit between the BCM C4 harness connector and the DLC.

Is the resistance below 5.0 ohms?

Yes
1. Go To step 6.
No
1. Repair the (D72) Diagnostic CAN C (+) circuit for an open.
2. Perform BODY VER TEST - VER 1 .
(D71) DIAGNOSTIC CAN C (-) CIRCUIT OPEN

Measure the resistance of the (D71) Diagnostic CAN C (-) circuit between the BCM C4 harness connector and the DLC.

Is the resistance below 5.0 ohms?

Yes
1. Inspect the wiring and connectors for damage or shorted circuits. If ok, replace the Body Control Module in accordance with the service information.
2. Perform BODY VER TEST - VER 1 .
No
1. Repair the (D71) Diagnostic CAN C (-) circuit for an open.
2. Perform BODY VER TEST - VER 1 .
