Circuit/System Testing
NOTE:
- Refer to: SIR Service Precautions
- Inspect the terminals of the following components and connectors for damage or corrosion and repair or replace as necessary:
- P14 Passenger Air Bag Disabled Indicator & Harness Connector
- K36 Inflatable Restraint Sensing and Diagnostic Module & Harness Connector
- Ignition Off
- Disconnect the component: P14 Passenger Air Bag Disabled Indicator
- Test for less than 10 ohms between the test points: Ground circuit terminal 1 & Ground
- If 10 ohms or greater
- Ignition Off
- Test for less than 2 ohms between the test points: Ground circuit & The other end of the circuit
- If 2 ohms or greater - Repair the open/high resistance in the circuit.
- If less than 2 ohms - Repair the open/high resistance in the ground connection.
- Go to next step: If less than 10 ohms
- Connect a test lamp between the test points: Control circuit terminal 4 & Ground
- Ignition - On / Vehicle - In Service Mode
- Perform the scan tool control function: Passenger Seat Belt Reminder Indicator - On and Off
- If the test lamp is always On
- Ignition Off
- Disconnect the electrical connector: K36 Inflatable Restraint Sensing and Diagnostic Module
- Ignition - On / Vehicle - In Service Mode
- Test for less than 1 V between the test points: Control Circuit & Ground
- If 1 V or greater - Repair the short to voltage on the circuit.
- If less than 1 V - Replace the component: K36 Inflatable Restraint Sensing and Diagnostic Module
- If the test lamp is always Off
- Disconnect the electrical connector: K36 Inflatable Restraint Sensing and Diagnostic Module
- Test for infinite resistance between the test points: Control Circuit & Ground
- If less than infinite resistance - Repair the short to ground on the circuit.
- Test for less than 2 ohms between the test points: Control Circuit @ Component harness & The other end of the circuit
- Test for less than 2 ohms between the test points: Ground @ Component harness & The other end of the circuit
- If 2 ohms or greater - Repair the open/high resistance in the circuit.
- If less than 2 ohms - Replace the component: K36 Inflatable Restraint Sensing and Diagnostic Module
- Go to next step: If the test lamp turns On and Off
- Replace the appropriate component: P14 Passenger Air Bag Disabled Indicator
