Pinpoint Test B: The Power Seat Is Inoperative - Passenger, With Power Recline
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 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 correct Restraints Control Module (RCM) fuse is removed and the ignition is ON.
NOTE:
The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
- B1 CHECK CIRCUIT SBB61 (GY/RD) FOR VOLTAGE
- Ignition OFF.
- Depower the SRS . Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Disconnect: Passenger Seat Side Air Bag C327.
- Disconnect: Passenger Seat Control Switch C3026.
- Connect the battery ground cable. Refer to BATTERY, MOUNTING AND CABLES .
- Measure the voltage between passenger seat control switch C3026-5, circuit SBB61 (GY/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.- Yes: GO to B2 .
- No:
VERIFY Battery Junction Box (BJB) fuse 61 (30A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the SYSTEM WIRING DIAGRAMS
for Edge or SYSTEM WIRING DIAGRAMS
for MKX to identify possible causes of the circuit short. TEST the system for normal operation.
DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C327.
REPOWER the SRS . REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- B2 CHECK CIRCUIT GD145 (BK/BU) FOR AN OPEN
- Measure the resistance between passenger seat control switch C3026-3, circuit GD145 (BK/BU), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes:
INSTALL a new passenger seat control switch. REFER to SEAT CONTROL SWITCH - FRONT . TEST the system for normal operation.
DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C327.
REPOWER the SRS . REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- No:
REPAIR the circuit. TEST the system for normal operation.
DISCONNECT the battery ground cable. CONNECT passenger seat side air bag module C327.
REPOWER the SRS . REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
