PACCAR Incorporated
The problem
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH CUMMINS ISC ENGINES. DIODES (ELECTRONIC DEVICES THAT RESTRICT CURRENT FLOW) CONTAINED IN THE PRE-HEAT CIRCUIT OF CERTAIN ENGINE WIRING HARNESSES WERE NOT PROPERLY INSULATED DURING THE HARNESS MANUFACTURING PROCESS.
Risk
THIS LACK OF INSULATION COULD ALLOW THE DIODES TO CONTACT EACH OTHER. ANY CONTACT BETWEEN THE DIODES COULD LEAD TO A SHORT CIRCUIT AND POSSIBLY A VEHICLE FIRE.
What owners should do
DEALERS WILL INSPECT THE HARNESSES AND REMEDY, IF REQUIRED, BY PROPERLY INSULATING THE DIODES. OWNER NOTIFICATION BEGAN JUNE 22, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT PETERBILT AT 1-940-591-4000.
