3. Ignition ON, verify the scan tool Deployment Loop Resistance parameter is greater than 5.12 ohm.

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

4. Install a 3 A fused jumper wire between the following control circuit terminals. Verify the scan tool Deployment Loop Resistance parameter

is less than 1.8 ohm.

* circuit terminal 1 X1 and terminal 2 X1

* circuit terminal 4 X1 and terminal 3 X1

瀚慖f greater than the specified range, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal,

replace the K36 SDM.

5. If all circuits test normal, test or replace the F107 driver steering wheel air bag.
