Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. With the scan tool, read ORC DTCs and record on the repair order.
2. Record the Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read ORC DTCs.
  Did the DTC return?
  
  Yes
  - Go to 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK THE SWITCH CIRCUITS FOR SHORT TO GROUND
1. Disconnect the switch connector and the related Occupant Restraint Controller (ORC) connector.
  NOTE:
  Probing of the circuit cavities at the Occupant Restraint Controller (ORC) body harness connectors and in-line connectors using test kit 2022900080 for back probing the terminal will prevent vehicle wiring harness connector damage during diagnostic procedures.
2. Check for continuity between ground and both of the switch circuits at the switch harness connector.
  Is there continuity between ground and either circuit?
  
  Yes
  - Repair the switch circuit(s) for a short to ground.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go to 3
CHECK THE SWITCH CIRCUITS FOR A SHORT TOGETHER
1. Check for continuity between the switch circuits at the switch harness connector.
  Is there continuity between the switch circuits?
  
  Yes
  - Repair the short between the switch circuits.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go to 4
CHECK THE SWITCH CIRCUITS FOR AN OPEN OR HIGH RESISTANCE
1. Measure the resistance of the switch circuits from the switch harness connector to the ORC harness connector.
  Is the resistance below 3.0 Ohms on either circuit?
  
  Yes
  - Go to 5
  No
  - Repair the switch circuit(s) for an open or high resistance.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK THE SWITCH CIRCUITS FOR A SHORT TO VOLTAGE
1. Measure the voltage between ground and the switch circuits at the switch connector.
  Is there any voltage present on either circuit?
  
  Yes
  - Repair the switch circuit(s) for a short to voltage.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go to 6
REPLACE THE AFFECTED SWITCH
1. Replace the affected switch in accordance with Service Information. Refer to BUCKLE, SEAT BELT, REMOVAL .
2. Connect any connectors removed during testing.
3. Turn the ignition on.
4. Clear DTC and note if it returns.
  Did the DTC return?
  
  No
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  Yes
  
  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 Occupant Restraint Controller (ORC) in accordance with Service Information. Refer to CONTROLLER, OCCUPANT RESTRAINT (ORC), REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
