This bulletin is being revised to update the correction procedure and parts and warranty information. Please discard Corporate Bulletin Number
43-81-01A (Section 8 - Chassis/Body Electrical).
Condition
Some owners may experience interior lights staying "ON" after all doors are closed and after the Multi-Function Alarm Module's inadvertent lighting
function has timed out, causing battery rundown. In the Corsica/Beretta, the Multi-Function Alarm Module will automatically turn off the interior lights
after 20 minutes. The Cavalier and Sunbird's interior lights will continue to light indefinitely.
Cause
The LH and/or RH front door handle switch(es) may be providing a resistive path to ground which may cause the Multi-Function Alarm Module to sense
that the door(s) are falsely open.
Correction
Follow the diagnostic procedure as listed below. If a resistance other than the specified value registers during testing, replace the malfunctioning door
handle switch, (see P/N chart). Continue through the entire test to check that both the RH and LH door handle switches are functioning properly.
1.
Disconnect the Multi-Function Alarm Module.
2.
With the LH front door open, measure the resistance from:
Term "J" to Term "P" (J Car)
CONN C1, Term "H" to CONN C2, Term "E" (L Car)
Resistance should be between 0 - 0.5 Ohms.
3.
With the LH front door closed, measure the resistance from:
Term "J" to Term "P" (J Car)
CONN C1, Term "H" to CONN C2, Term "E" (L Car)
Resistance should be > 30 Mega Ohms.
4.
With the RH front door open, measure the resistance from:
Term "K" to Term "P" (J Car)
CONN C1, Term "G" to CONN C2, Term "E" (L Car)
Resistance should be between 0 - 0.5 Ohms.
5.
With the RH front door closed, measure the resistance from:
Term "K" to Term "P" (J Car)
