The problem
VEHICLE DESCRIPTION: HEAVY DUTY CLASS 8 TRUCKS. THE ANTILOCK BRAKE SYSTEM (ABS) WIRE IN THE TRAILER CABLE JUNCTION BOX AT THE END OF THE FRAME MAY NOT CONTAIN POWER FOR THE TRAILER ABS AS REQUIRED BY FMVSS NO. 121, "AIR BRAKE SYSTEMS."
Risk
UNDER A HEAVY BRAKE APPLICATION (LOCK UP), A NON-FUNCTIONING TRAILER ABS COULD ALLOW THE TRAILER TO SKID, INCREASING THE RISK OF A CRASH.
What owners should do
DEALERS WILL INSTALL THE ELECTRICAL CIRCUIT REQUIRED TO ACTIVATE THE CENTER PIN OF THE TRAILER CABLE CIRCUIT.
