Diagnostic Test

CHECK FOR AN ACTIVE DTC
NOTE:
The use of a approved special tool or Digital Multimeter such as a Fluke Meter that will not apply more than 20 milliamperes to a circuit are the only measurement tools to be used.

NOTE:
Probing of the circuit cavities at the Occupant Restrain Controller (ORC) Module C1-A, C1-B, or C2-A body harness connectors is only to be done with a approved test lead from the 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures (special tool #10159, Test Leads, Dedicated)
1. With the scan tool, read Radio DTCs and record on the repair order.
2. Turn the ignition on.
3. With the scan tool, erase DTCs.
4. Wait 30 seconds.
5. With the scan tool, read DTCs.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - 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. If no problems are found, test complete.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK FOR VOLTAGE ON THE (R41) AUTOMATED COLLISION NOTIFICATION CIRCUIT
1. Turn the ignition off.
2. Disconnect the Radio (RRM) C1 harness connector.
3. Turn the ignition on.
4. Measure for voltage on the (R41) Automated Collision Notification circuit at the radio (RRM) connector PIN 3.
  Is there any voltage present?
  
  Yes
  - Replace the Radio in accordance with the Service Information. Refer to RADIO, REMOVAL AND INSTALLATION .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 3
CHECK THE (R41) AUTOMATED COLLISION NOTIFICATION 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.

Turn the ignition off.
1. Disconnect the Radio harness connector and ORC harness connector.
3. Measure the resistance of the (R41) Automated Collision Notification circuit between the Radio harness connector and the ORC harness connector.
  Is the resistance above 2.0 Ohms?
  
  Yes
  - Repair the open in the (R41) Automated Collision Notification circuit according to the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  
  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.
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC Module according to the Service Information. Refer to MODULE, OCCUPANT RESTRAINT (ORC), REMOVAL AND INSTALLATION .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
