File In Section: 3 - Steering/Suspension
Bulletin No.: 53-34-07
Date: January, 1996
Subject:
RSS Codes Displayed or Electronic Leveling Control (ELC) Compressor Inoperative (Diagnose/Replace)
Models:
1993-96 Cadillac Eldorado, Seville
1994-96 Cadillac Concours, DeVille
Condition
Some Road Sensing Suspension (RSS) equipped vehicles may exhibit RSS codes S037, RS0037, S038 or RSOO38 or an inoperative Electronic Leveling
Control (ELC) compressor.
Cause
This condition may be caused by ingestion of moist air through a leak, cut or damaged air line resulting in moisture condensation inside the ELC
compressor. This, in turn, causes corrosion resulting in compressor failure.
Correction:
1.
Diagnose RSS codes per Section 3G2 of the Service Manual. Diagnose ELC compressor inoperation per Section 3D1 of the Service Manual.
2.
If trouble tree leads to "repair compressor" or "replace ELC compressor head assembly", perform the following:
a.
Replace all lines from the compressor to both rear shocks.
b.
Replace the ELC compressor assembly.
Notice: Damaged air lines may result from misplaced or missing air line mounting clips. See Figure 1, Item 1 for proper mounting clip location. Assure
proper location/presence of the vent line and filter.
