Air Bag Control Module: Service and Repair

SRS Unit Removal and Installation

Removal:

CAUTION:
- Before disconnecting the airbag connector(s), turn off the ignition switch and wait for at least 3 minutes to let the capacitor in the back-up circuit discharge. This will prevent a malfunction of the seat belt pretensioners.
- Before disconnecting any part of the SRS wire harness, install short connectors (RED) on the air- bag(s) and both seat belt pretensioners. After installing the short connector(s) on the airbag(s), immediately install one Short Connector "A" (Tool Number O7MAZSPOO2OO) on the cable reel connector (for the driver's airbag), and another on the SRS main harness connector (for the passenger's airbag). This will prevent any static electricity from triggering the seat belt pretensioners before you disconnect them - refer to "Short Connector Installation" procedure.
- Do not damage the SRS unit terminals or connectors.
- Do not disassemble the SRS unit; it has no serviceable parts.
- Store the SRS unit in a clean, dry area.
- Do not use any SRS unit which has been subjected to water damage or shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
