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 INTERMITTENT TEST .
CHECK THE SENSOR CIRCUITS FOR AN OPEN OR HIGH RESISTANCE
1. The ignition must be off when checking the continuity of a circuit.
2. Isolate the circuits by disconnecting the Electronic Control Unit (ECU) and the component harness connector containing the circuit being tested. Note: Use the appropriate wiring diagram as a guide to follow the path of the circuit.
3. Before measuring the resistance of any circuit, first measure the resistance between the two leads of the DVOM. Note: The meter leads can add resistance to the measurement value.
4. Connect one lead of the DVOM to the circuit being tested at the component harness connector.
5. Connect the other lead to the circuit being tested at the ECU harness connector and measure the resistance of the circuit.
Is the resistance below 3.0 Ohms on either circuit?

Yes
- Go To 3
No
- Repair the sensor circuit(s) for an open or high resistance.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
REPLACE THE AFFECTED SENSOR
1. Replace the affected sensor in accordance with Service Information. Refer to BUCKLE, SEAT BELT, REMOVAL AND INSTALLATION .
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
  - Replace the Occupant Classification Module (OCM) in accordance with Service Information. Refer to MODULE, OCCUPANT CLASSIFICATION (OCM), REMOVAL AND INSTALLATION .
    .
  - Perform the Occupant Classification Module (OCM) Verification Test. Refer to OCCUPANT CLASSIFICATION MODULE (OCM) VERIFICATION TEST .
