AND ELECTRICAL RELAYS

TO:
All Pontiac Dealers
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be
adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within sixty days after tender of a
vehicle is prima facie evidence of failure to repair within a reasonable time.
If the condition is not adequately repaired within a reasonable time, the owners may be entitled to an identical or reasonably equivalent vehicle at no
charge or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair
their vehicle as soon as possible.. As you will see in reading the attached copy of the letter which is being sent to owner's, the owner's are being
instructed to contact the nearest Pontiac Customer Assistance Center if their dealer does not remedy the condition within five days of the mutually agreed
upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Safety
Administration.
Condition & Vehicle Involved, Owner Notification & Dealer Campaign Information
CONDITION INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety may exist in some 1986 and 1987 Pontiac 6000, STE models,
equipped with Anti-Lock Brake System (ABS).
Involved 1986 model year vehicles may exhibit brake fluid seepage from the ABS pressure/warning switch which eventually can lead to loss of the brake
system hydraulic pump motor. Additionally, on both 1986 and 1987 involved vehicles, the hydraulic pump motor and ABS electrical relays may have
been exposed to water contamination during vehicle assembly. This condition can cause loss of the hydraulic pump motor and/or loss of the ABS
function.
Loss of the hydraulic pump motor would, after accumulated pressure has been depleted (approximately 10-30 normal stops), result in a total loss of rear
brakes as well as power assist to the front brakes. The red "Brake" warning light would, before accumulated pressure has been depleted, illuminate and
stay. ON. If this warning is not heeded, a loss of rear brakes at a time when minimum stopping distance is required could result in a vehicle crash.
An inoperative ABS electrical relay could cause loss of the ABS function, but normal power assisted braking would be retained. The amber "Anti-Lock"
warning light would illuminate and stay ON.
To correct these conditions, on 1987 model year vehicles, both the ABS and hydraulic pump motor relays will be replaced. On 1986 model year
vehicles, both the ABS and hydraulic pump motor relays and 30 amp fuses will be replaced. In addition, on 1986 models, the hydraulic pump motor
assembly and pressure/warning switch will be inspected and, if required, replaced.
