Circuit/System Testing

NOTE:

When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.

Seat belt switch - driver
Inflatable restraint sensing and diagnostic module

Ignition OFF, disconnect the harness connector at the driver seat belt switch.
Test for less than 5 Ω between the low reference circuit terminal B and ground.
- If 5 Ω or greater
1. Ignition OFF, disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
2. Test for less than 2 Ω in the low reference circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the Inflatable Restraint Sensing and Diagnostic Module.
- If less than 5 Ω
Ignition OFF, disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module, ignition ON.
Test for less than 1 V between the harness connector terminal 3 and ground.
- If 1 V or greater
  Repair the short to voltage on the circuit.
- If less than 1 V
Test for infinite resistance between the harness connector terminal 3 and ground.
- If less than infinite resistance
  Repair the short to ground on the circuit.
- If infinite resistance
Test for less than 2 Ω between Inflatable Restraint Sensing and Diagnostic Module - terminal 3 and the seat belt switch - driver terminal A end to end.
- If 2 Ω or greater
  Repair the open/high resistance in the circuit.
- If less than 2 Ω
Replace the seat belt switch - driver.
Operate the vehicle under the conditions for setting the DTC. The DTC should not set.
- If the DTC sets
  Replace the Inflatable Restraint Sensing and Diagnostic Module.
- If the DTC does not set
All OK.
