Detect and Erase DTC

Airbag sensor assembly
Negative (-) terminal
In systems that have a self-diagnosis function, such as the SRS airbag system, DTCs are stored in the Airbag Sensor Assembly when a malfunction occurs. Connecting the battery or turning the ignition switch on when connectors and parts are removed could cause the Airbag Sensor Assembly to detect a DTC. In this case, it is necessary to erase the stored DTC after completing the work. Erasing procedures differ according to the system, so perform the work by following the Repair Manual.
