2. Disconnect the scan tool.

3. Wait for 120 seconds and then test for greater than 25 ohm between the seat belt anchor pretensioner control circuits terminal 1 and terminal

2.

瀚慖f less than the specified range, test for a short between the control circuits, check each connector and CPA to ensure that the shorting

bars are lifted. If the circuits and shorting bars tests normal, replace the K36 SDM.

4. Ignition ON, test for less than 11 V between each of the seat belt anchor pretensioner control circuit terminals 1 and 2 and ground.

瀚慖f greater than the specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the K36 SDM.

5. Ignition OFF, test for greater than 25 ohm between each of the seat belt anchor pretensioner control circuit terminals 1 and 2 and ground.

瀚慖f less than the specified range, test the control circuit for a short to ground. If the circuit tests normal, replace the K36 SDM.

6. Install a 3 A fused jumper wire between the seat belt anchor pretensioner control circuits terminal 1 and terminal 2.

7. Verify the scan tool Deployment Loop Resistance parameter is less than 2 ohm.

瀚慖f greater than the specified range, test the control circuit terminals 1 and 2 for an open/high resistance. If the circuits test normal, replace

the K36 SDM.

8. If all circuits test normal, replace the F113 seat belt anchor pretensioner.
