Circuit Description
When you first turn the ignition switch to the RUN position, the inflatable restraint sensing and diagnostic module (SDM) performs tests to diagnose critical malfunctions within itself. Next the SDM measures IGNITION voltage to make sure it is within its respective normal voltage range. Then the SDM proceeds with the DEPLOYMENT LOOP CONTINUITY test. During the DEPLOYMENT LOOP CONTINUITY test, the SDM measures the voltage difference between Passenger Side High and Passenger Side Low.

Conditions for Setting the DTC
- The passenger side air bag deployment loop resistance is more than 500 ohms.
- The malfunction must be present for at least 500 milliseconds during one of the following tests:
- DEPLOYMENT LOOP CONTINUITY
If the malfunction is detected in this test, the RESISTANCE MEASUREMENT test will not be performed.
- CONTINUOUS MONITORING

Action Taken When the DTC Sets
- The SDM sets a Diagnostic Trouble Code.
- The SDM turns ON the AIR BAG warning lamp.

Conditions for Clearing the DTC
- Current DTC
The passenger side air bag deployment loop resistance is less than 100 ohms for 500 milliseconds.
- History DTC
- You issue a scan tool CLEAR CODES command.
- Once 250 malfunction free ignition cycles have occurred.

Diagnostic Aids
The following can cause an intermittent Condition:
- A poor connection at the inflatable restraint passenger seat module harness connector terminals A and B.
- A poor connection at the SDM terminals 13 and 14.
- An open in CKT 2135.
- An open in CKT 2136.
When measurements are requested in this table, use J 39200 Digital Multimeter with the correct terminal adapter from J 35616-A Connector Test Adapter Kit. When a check for proper connection is requested, refer to Intermittents and Poor Connections. When a wire, connector or terminal repair is requested, use J 38125-A Terminal Repair Kit and refer to Wiring Repair. Intermittent Problems Service and Repair

Test Description
The numbers below refer to the step numbers on the diagnostic table:
2. This test determines the deployment loop resistance measured by the inflatable restraint sensing and diagnostic module (SDM).
3. This test checks for proper contact or corrosion of the yellow 2-way connector.
10. This test isolates the malfunction to one side of the inflatable restraint front side impact module (RH) yellow 2-way connector.
12. This test checks for proper contact or corrosion of the SDM connector.
17. This test determines whether the malfunction is in CKT 2155.
19. This test determines whether the malfunction is in CKT 2136.
