# H/LAMP ACTUATOR CONTROL MODULE PARTS SYSTEM ERROR (NEW P/N)

#### SUBJECT: HEADLAMP ACTUATOR CONTROL MODULE-PARTS SYSTEM ERROR

#### VEHICLES AFFECTED: 1990-91 E

Headlamp actuator control module part number 16509097 was incorrectly superseded to 16514174 for 1990 and 1991 Toronados and Trofeos.

When servicing the headlamp actuator control module on 1990-1991 Toronados/Trofeos, use P/N 16509097. The parts book is being corrected.

o The 16514174 is for a Pontiac Firebird application and has not been released for use on Toronados/Trofeos.

o The 16514174 module is similar in appearance to the 16509097 module and may appear to function when initially installed.

o All 1990 and 1991 Toronados/Trofeos were built with 16509097 modules and should be serviced with that part number.

To diagnose headlamp door conditions refer to Section 8A-102 of the Service Information Manual.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
