BULLETIN NO.: 99-T-43ISSUE DATE: September, 1999
GROUP/SEQ. NO.: Electrical-03
CORPORATION NO.: 99-08-45-002
SUBJECT:
Remote Keyless Entry (RKE) or Security System Inoperative and/or Engine
Will Not Crank, Power Door Locks Inoperative or Intermittently
Inoperative, Power Windows Inoperative, Power Mirror Inoperative, Door
Speaker Volume Cutting Out, 1OA BODY Fuse Open or 1OA CHIME Fuse
Open (Repair Body Wiring Harness)
MODELS AFFECTED:
1996 - 1999 Saturn S-Series Sedans and Wagons
CONDITION:
Customer may comment that on occasion, one or more of the following conditions occur:
^ Remote keyless entry (RKE) or security system inoperative, and/or engine will not crank. (Must be equipped with RPO code AUO.)
^ Power door locks inoperative or intermittently inoperative. (Must be equipped with RPO code AUO.)
^ Power windows inoperative. (Must be equipped with RPO code A31.)
^ Power mirror inoperative. (Must be equipped with RPO code D35.) Front door speaker volume cuts out intermittently.
CAUSE:
The cause of the above conditions may be the main body to front door wire harness coming into contact with front door hinge reinforcement bracket. (Refer to illustration.)
The harness is routed into the front doors through a grommet as it enters the outer door structure. It is then routed across the front door hinge reinforcement (about 51 mm [2 in.] from end of grommet) before it is anchored by a rosebud. Depending on variation in either the manufacturing or routing of the wire harness, there is a chance that the wire harness can come into contact with hinge reinforcement bracket and chafe, causing a short to ground on one or more of the circuits listed in this bulletin.
IMPORTANT:
On 1996 model year vehicles, Circuit 294 from RKE and security system module may be affected, but will not cause an engine no crank condition.
^ Circuit 294/TAN (driver's door unlock output from RKE and security system module) - Engine will not crank and RKE and security system inoperative. A short to ground on this circuit may cause internal damage to the RKE and security system module. On 1997 vehicles (up to and including VZ264043) the 10A BODY fuse may be open. On 1997 vehicles (after VZ264043), 1998, and 1999 model year vehicles, the 1OA CHIME fuse may be open.
^ Circuit 294/TAN (right front door lock motor), and Circuit 295/GRA (right and left front door lock motor) - Power door locks may be inoperative due to an open on the 20A LOCKS fuse.
^ Circuit 340/ORN, 194/WHT, 195/LT BLU (power door lock switch circuit)
- Power door locks may be inoperative due to an open on the 10A BODY fuse.
^ Circuit 164/DK BLU, 165/BRN (left front power window motor) or Circuit 166/LT BLU, 167/TAN (right front power window motor) - Power window(s) may be inoperative due to an open on the 30A PWR CONVCE fuse.
^ Circuit 81/WHT, 82/LT BLU, 89/LT GRN (Passenger side power mirror) - Power mirror may be inoperative due to an open on the 1OA BODY fuse.
^ Circuit 2OO/LT GRN, 117/DK GRN (right front speaker) and/or Circuit 201/TAN, 118/GRA (left front speaker) - Door speaker volume cutting out.
