Circuit/System Testing

• If 10 ohms or greater 

1. 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 

Test for less than 11 V between the test points: Control circuit terminal 4 & Ground

• If 11 V or greater 

1. Ignition/Vehicle & All vehicle systems - Off
2. Before attempting these procedures, the SIR system must be disabled.
3. Disconnect the electrical connector: K36 Inflatable Restraint Sensing and Diagnostic Module
4. Ignition - On / Vehicle - In Service Mode
5. Test for less than 1 V between the test points: Control circuit terminal @ Component harness & 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 less than 11 V 

Test for greater than 4 V between the test points: Control circuit terminal 4 & Ground

• If 4 V or less 

1. Ignition/Vehicle & All vehicle systems - Off
2. Before attempting these procedures, the SIR system must be disabled.
3. Disconnect the electrical connector: K36 Inflatable Restraint Sensing and Diagnostic Module
4. Test for infinite resistance between the test points: Control circuit terminal @ Component harness & Ground
   • If less than infinite resistance - Repair the short to ground on the circuit.
5. Test for less than 2 ohms between the test points: Control circuit terminal @ Component harness & Control circuit terminal @ Control module harness
   • 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

• If greater than 4 V
