Defect description
ON CERTAIN TRUCKS WITH AIR BRAKES, THE AIR MANAGEMENT UNIT INTRODUCED WITH M2 TRUCKS INCLUDES A PRESSURE SWITCH ASSEMBLY (PSA) MODULE FOR THE LOW AIR PRESSURE INDICATOR AND STOP LAMP CONTROL FUNCTIONS. THE PSA MODULE COVER ALLOWS WATER INGRESSION THAT COULD CAUSE THE STOP LAMP SWITCH TO SHORT "ON." THE STOP LAMP SHORT CAN BE INTERMITTENT OR WITH THE KEY OFF.
Safety risk
THIS COULD CAUSE THE STOP LIGHTS TO ILLUMINATE CONTINUALLY AND NOT ALLOW OTHER DRIVERS TO SEE WHEN THE BRAKES ARE BEING APPLIED WHICH COULD RESULT IN A CRASH.
Manufacturer remedy
DEALERS WILL INSPECT THE PRESSURE WSWITCH A MODULE AND ELECTRICAL CONNECTORS AND REPLACE IF NECESSARY. OWNER NOTIFICATION BEGAN ON AUGUST 15, 2003. 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 FREIGHTLINER AT 1-800-547-0712.
