Pinpoint Test B: The Power Seat Is Inoperative-Passenger

B1 CHECK CIRCUIT 51 (BK/WH) FOR VOLTAGE
WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.

NOTE: If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered. Refer to SUPPLEMENTAL RESTRAINT SYSTEM article.

NOTE: The air bag warning lamp illuminates when the 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.
- 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 article.
- Disconnect: Passenger Safety Belt Buckle Pretensioner C303
- Connect: Restraint System Diagnostic Tool 501-097 to the Passenger Safety Belt Buckle Pretensioner C303
- Disconnect: Passenger Seat Side Air Bag C337 (Vehicles With Seat Side Air Bags Only)
- Connect: Restraint System Diagnostic Tool 418-133 to the Passenger Seat Side Air Bag C337 (Vehicles With Seat Side Air Bags Only)
- Connect the battery ground cable.
- Disconnect: Passenger Seat Control Switch C330
- Measure the voltage between passenger seat control switch C330-H, circuit 51 (BK/WH), harness side and ground.
- Is the voltage greater than 10 volts?
1. YES : Go to B2.
2. NO : VERIFY the bussed electrical center (BEC) fuse 15 (30A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
  DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger safety belt buckle pretensioner C303. CONNECT passenger safety belt buckle pretensioner C303.
  
  For vehicles with seat side air bags, DISCONNECT the restraint system diagnostic tool from passenger seat side air bag C337. CONNECT passenger seat side air bag C337.
  
  REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM article.
B2 CHECK CIRCUIT 1205 (BK) FOR AN OPEN
- Measure the resistance between passenger seat control switch C330-E, circuit 1205 (BK), harness side and ground.
- Is the resistance less than 5 ohms?
1. YES : INSTALL a new passenger seat control switch. TEST the system for normal operation.
  DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger safety belt buckle pretensioner C303. CONNECT passenger safety belt buckle pretensioner C303.
  
  For vehicles with seat side air bags, DISCONNECT the restraint system diagnostic tool from passenger seat side air bag C337. CONNECT passenger seat side air bag C337.
  
  REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM article.
2. NO : REPAIR the circuit. TEST the system for normal operation.
  DISCONNECT the battery ground cable. DISCONNECT the restraint system diagnostic tool from passenger safety belt buckle pretensioner C303. CONNECT passenger safety belt buckle pretensioner C303.
  
  For vehicles with seat side air bags, DISCONNECT the restraint system diagnostic tool from passenger seat side air bag C337. CONNECT passenger seat side air bag C337.
  
  REPOWER the supplemental restraint system (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM article.
