Date: February, 1996
Subject:
Amber Antilock Warning Light and (if Equipped) Amber Traction Off Warning Light Stays On (Apply Sealant/Grease)
Models:

Condition
Some owners may comment that the amber antilock warning light and (if equipped) amber traction off warning light stays on. Also, the antilock brake
system and (if equipped) traction control system may become inoperative. The following conditions will occur:
^
Amber antilock warning light and (if equipped) amber traction off warning light turns on and stays on. The red brake warning light stays off.
^
EBTCM Diagnostic Trouble Code (DTC) 61 will be set.
Important:
THIS CONDITION IN NO WAY AFFECTS THE OPERATION OF THE POWER BRAKES.
Cause
Fluids trapped in the wire harness in the area below the windshield washer reservoir. This allows the fluids to come in contact with the ground splice for
the Pressure Modulator Valve (PMV) motor (S129) and to be wicked down CKT 1150 to the 4-way brake PMV connector C2. Sufficient fluids in the
connector interfere with the pump run signal, causing a DTC 61 to set. This condition DOES NOT damage the Electronic Brake Traction Control
Module (EBTCM).
Correction
Seal splice S129 with electrical moisture sealant, P/N 11515174. Cut sealant into approximately a 2" x 2" square. Position seam in flexible conduit down
or slit the bottom of the conduit in area of splice S129 and apply electrical connector grease, P/N 12377900, to terminals in connector C2.
Procedure
1.
Remove air cleaner and windshield washer reservoir. For 3800 super charged engines, if equipped, remove the auto level control air compressor.
