This bulletin is being revised to correct text in Paragraph 1. Please discard Corporate Bulletin Number 53-81-25 (Section 8 - Chassis/Body Electrical).
When placing the Multi-function Alarm Module in the Power Output Diagnostic Mode, 4 failure modes can be set. The 1995 and 1996 Service
information does not list the fourth failure mode and should be updated as follows.
When the Multi-function Alarm Module chimes 4 times every 3 seconds during the Power Output Diagnostic Mode, a failure of the seat belt door
retractor solenoids has been detected and the appropriate diagnostic chart in Section 8A-146 should be referred to. Once the necessary repairs have been
performed, reset the Multi-function Alarm Module by removing fuse 11 or the Alarm fuse as noted in Section 8A-76.
The procedure to place the Multi-function Alarm Module in the Power Output Diagnostic Mode is listed in Section 8A-76 but should also be added to
Section 8A-146. The procedure is as follows:
Close front doors.
Set park brake.
Turn interior lights on using panel dimmer switch.
Turn ignition switch to "Run" and before 15 seconds elapse, perform the following steps:
Open RH front door.
Cycle headlamp switch from "Park" to "Off" 3 times.
