Pinpoint Test B: The Power Seat Is Inoperative - Driver, Without Power Recliner
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The air bag warning indicator illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
NOTE:
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- B1 CHECK CIRCUIT SBB60 (GN/RD) FOR VOLTAGE
- Key in OFF position.
- Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .
- Disconnect: Driver seat side air bag C328
- Disconnect: Driver seat safety belt buckle pretensioner C3201
- Disconnect: Driver Seat Control Switch C352
- Connect the battery ground cable.
- Measure the voltage between driver seat control switch C352-4, circuit SBB60 (GN/RD), harness side and ground.
- Is the voltage greater than 10 volts?
WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any air bag module when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.Courtesy of FORD MOTOR CO.
- YES : Go to B2.
