B0018 PONTIAC Meaning
The deployment loop of the Instrument Panel (I/P) airbag module consists of a two-stage I/P module, an I/P module high control module, and I/P module low control circuits for both stages 1 and 2. There are 2 shorting bars used in the I/P module connector that 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 helps prevent unwanted deployment of the airbag module during maintenance. When the ignition is turned ON, the Sensing and Diagnostic Module (SDM) performs continuous diagnostic tests on the deployment loops to check for circuit continuity and shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.
