Glossary of Terms Used

Air Bag Simulator
Air bag simulators are used to simulate air bag module connections to the system.

Disconnect the Component
Disconnect the component means disconnect the component vehicle harness connector. It does not mean remove the component. Do not reconnect a disconnected component unless instructed to do so.

Deactivate the System
Deactivate the system means to carry out the deactivation procedure. For additional information, refer to the Deactivation Procedure. Service and Repair

Prove Out the System
Prove out the system means to turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then switch off for a further two seconds. If an air bag SRS fault is present, the air bag indicator will either:

- Fail to light if the lamp has a fault.
- Remain lit continuously if the RCM does not receive power or is disconnected, or if the lamp has flashed the fault code five times within that ignition cycle.
- Flash the fault code.

The fault codes (if present) will occur after the 8 second prove out period. Within the prove out period, the RCM will carry out a self diagnostic check as well as checking the whole air bag restraint system. If the air bag indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of five sets of five beeps.
If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.

Reactivate the System
Reactivate the system means to carry out the reactivation procedure. For additional information, refer to the Reactivation Procedure. Service and Repair

Reconnect the System
Reconnect the system means to reconnect all system components. For additional information, refer to the Air Bag System Reconnect Checklist. Air Bag System Reconnect Checklist

Replace the Component

NOTE: Repair is made by replacement only. If a part is replaced and the new part does not correct the condition, install the original part and carry out the diagnostic procedure again.

Replace the component means to remove the existing component and replace it with an authorized replacement part obtained from Jaguar Cars Ltd. Replacing Components

Verify the System
Verify the system means to prove out the system with air bag simulators in place of the air bag modules the vehicle system.
