SIR Disabling and Enabling Zone 1

SIR DISABLING AND ENABLING ZONE 1

DISABLING PROCEDURE
1. Turn the steering wheel so that the vehicle's wheels are pointing straight ahead.
2. Turn the ignition switch to the OFF position.
3. Remove the key from the ignition switch.
4. Locate the body control module fuse center.




5. Locate and remove the AIR BAG (IGN) and AIR BAG (BATT) fuses from the body control module fuse center.

IMPORTANT: This SDM has two fused power inputs. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove both AIR BAG (IGN) and AIR BAG (BATT) fuses from the body control module fuse center. With the AIR BAG fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate an SIR system malfunction.




6. Open front hood and locate the front end sensor, also known as the electronic frontal sensor (EFS) (2).
7. Remove the connector position assurance (CPA) from the EFS connector.
8. Remove the EFS connector from the EFS (2).

ENABLING PROCEDURE
1. Remove the key from the ignition switch.




2. Connect the EFS connector to the EFS (2).
3. Connect the CPA to the EFS connector.




4. Install the AIR BAG (IGN) and AIR BAG (BATT) fuses into the body control module fuse center (1).
5. Use caution while reaching in and turn the ignition switch to the ON position. The AIR BAG indicator will flash then turn OFF.
6. Perform the SIR Diagnostic System Check if the AIR BAG warning indicator does not operate as described. Refer to Diagnostic System Check - Vehicle. Testing and Inspection
