Circuit/System Testing

Ignition OFF, disconnect the scan tool. It may take up to 2 minutes for all vehicle systems to power down. Disconnect the appropriate harness connector listed below:
- F112 Seat Belt Retractor Pretensioner
- F113 Seat Belt Anchor Pretensioner
Test for greater than 25 Ω between the appropriate control circuit terminals listed below:
- F112 Seat Belt Retractor Pretensioner terminals 1 and 2
- F113 Seat Belt Anchor Pretensioner terminals 1 and 2
- If 25 Ω or less
1. Disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module.
2. Test for infinite resistance between the 2 control circuits.
  NOTE: Some connectors may be equipped with shorting bars as a safety component to prevent accidental inflator deployment. When testing on a connector with shorting bars, the shorting bars must be disabled to ensure accurate test results. Insert an appropriate pick from EL-38125-580 and depress the shorting bars above the appropriate terminals. This will lift the shorting bar from the terminal and allow accurate test results. Take care not to damage the connector, shorting bar or terminal when depressing the shorting bar.
  - If less than infinite resistance, repair the short between the two circuits.
  - If infinite resistance, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If greater than 25 Ω
Ignition ON.
Test for less than 11 V between the control circuit terminals listed below and ground:
- F112 Seat Belt Retractor Pretensioner terminal 1
- F112 Seat Belt Retractor Pretensioner terminal 2
- F113 Seat Belt Anchor Pretensioner terminal 1
- F113 Seat Belt Anchor Pretensioner terminal 2
- If 11 V or greater
1. Ignition OFF, disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module, ignition ON.
2. Test for less than 1 V between each control circuit and ground.
  - If 1 V or greater, repair the short to voltage on the circuit.
  - If less than 1 V, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If less than 11 V
Ignition OFF. It may take up to 2 minutes for all vehicle systems to power down.
Test for greater than 25 Ω between the control circuit terminals listed below and ground:
- F112 Seat Belt Retractor Pretensioner terminal 1
- F112 Seat Belt Retractor Pretensioner terminal 2
- F113 Seat Belt Anchor Pretensioner terminal 1
- F113 Seat Belt Anchor Pretensioner terminal 2
- If 25 Ω or less
1. Disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module.
2. Test for infinite resistance between each control circuit and ground.
  - If less than infinite resistance, repair the short to ground on the circuit.
  - If infinite resistance, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If greater than 25 Ω
Install a 3 A fused jumper wire between the appropriate control circuit terminals listed below:
- F112 Seat Belt Retractor Pretensioner terminals 1 and 2
- F113 Seat Belt Anchor Pretensioner terminals 1 and 2
Ignition ON.
Verify the scan tool Deployment Loop Resistance parameter is less than 2 Ω.
- If 2 Ω or greater
1. Ignition OFF.
2. Disconnect the harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module.
3. Test for less than 2 Ω in each control circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If less than 2 Ω
Ignition OFF, connect the harness connector at the F112 Seat Belt Retractor Pretensioner or F113 Seat Belt Anchor Pretensioner, press in the CPA (if equipped) until an audible and/or tactile click is heard.
Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
Verify DTC B0015, B001A, B001B or B0022 is not set.
- If B0015, B001A, B001B or B0022 is set
  Replace the appropriate F112 Seat Belt Retractor Pretensioner or F113 Seat Belt Anchor Pretensioner.
- If DTC B0015, B001A, B001B or B0022 is not set
All OK.
