B0018 CADILLAC Description
The Inflatable Restraint Instrument Panel (I/P) module deployment loop consists of a dual stage I/P module, I/P module high control, and I/P module low control circuits for both stages 1 and 2. There are 2 shorting bars used within the I/P module connector which will short together the I/P module high and I/P module low control circuits for both stages 1 and 2 when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing. When the ignition is turned ON, the inflatable restraint Sensing and Diagnostic Module (SDM) performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.
