Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. 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:
  Make sure the battery voltage is between 10.0 and 16.0 volts.
2. With the scan tool, read the module status.
  NOTE:
  Check the BCM for any active CAN hardware DTCs, perform DTC before proceeding.
  
  Does the scan tool indicate that the module is active on the bus?
  
  Yes
  - 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.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To Step 2
CHECK THE (Z917) GROUND CIRCUIT FOR AN OPEN

WARNING:
Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the Occupant Restraint Controller Module harness connectors.
2. Connect the SRS Load Tool Adapter (special tool #8443-28, SRS Load Tool Adapter) to the ORC harness connectors.
3. Measure the resistance between ground and the (Z917) Ground circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To Step 3
  No
  - Repair the open in the (Z917) Ground circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (F929) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT FOR AN OPEN OR SHORT

NOTE:
Check the BCM for any ignition related DTCs before proceeding. If set. Refer to DIAGNOSIS AND TESTING .

WARNING:
Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Using a 12-volt test light connected to ground, check the (F929) Fused Ignition Switch Output (Run) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 4
  No
  - Repair the open or short in the (F929) Fused Ignition Switch Output (Run) circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (F945) IGNITION RUN/START CONTROL OUTPUT CIRCUIT FOR AN OPEN OR SHORT

1. Using a 12-volt test light connected to ground, check the (F945) Ignition Run/Start Control Output circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 5
  No
  - Repair the open or short in the (F945) Ignition Run/Start Control Output circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE (D11) AND (D12) CAN C BUS CIRCUITS FOR AN OPEN

1. Turn the ignition off.
2. Disconnect the Front CAN C Star Connector C2 harness connector.
3. Measure the resistance of the (D11) CAN C Bus (+) circuit between the Front CAN C Star Connector C2 harness connector and the Occupant Restraint Controller C2-A connector.
4. Measure the resistance of the (D12) CAN C Bus (-) circuit between the Front CAN C Star Connector C2 harness connector and the Occupant Restraint Controller C2-A connector.
  Are the resistances below 5.0 Ohms?
  
  Yes
  - Replace the Occupant Restraint Controller in accordance with the Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair the open in the (D11) CAN C Bus (+) or (D12) CAN C Bus (-) circuit.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
