ABS - Code 45 Set

File in Group 8
Number 127
Corp. Ref.No. 018121
Date Nov. 1990
SUBJECT: ABS CODE 45 DUE TO OPEN MAXI FUSE # 2
MODELS AFFECTED: 1991 DE VILLES AND FLEETWOODS (SOP TO VIN 223063)
Some 1991 DeVilles and Fleetwoods prior to VIN 223063 may experience an open maxi fuse # 2, 30 amp, in the left-hand under hood fuse block. This may cause ABS code 45 to set.
Circuit 1077, tan wire, may chafe against the ELC compressor bracket and short to ground causing maxi fuse to blow. This may also result in an open ELC motor ground wire as current from fuse # 2 shorts to ground through the ELC motor ground path.
Repair circuit 1077 if shorted to ground where the wire exits the conduit at the ELC compressor bracket. Inspect the other wires in the conduit with circuit 1077 for chafing and possible shorts. Inspect the ELC compressor ground wire for damage. Reinsert all wires back into the conduit near the ELC compressor bracket. Tape the conduit at the end so that wires cannot escape and so that no wires may chafe on the ELC bracket.
