Just bought a new Malibu 120 runs a few minutes and shuts off repeat ly after reset

Hi Tim, The link below is a short youtube video showing how to test and fix a car that shuts off randomly, Hope this helps.....CHEERS..


Fixing Car That Shuts Off Randomly

Not likely a grounding problem. Run a test: Turn on unit with NO sound into the mics and wait 5 minutes... now try the mics. If they start working for a few minutes, then the amp is being overdriven. These small systems can be overheated and a thermal protector shuts them down to protect them. A hidden problem is if the mics are in front of the speakers you MIGHT have ultrasonic (above hearing range) feedback that may be overheating the unit. Put your speakers nearer the audience and mics behind. If problem persists, exercise your warranty.

Sounds broke. What is model number, can't find afra.

PASSKEY LOCKOUT RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key.
If this doesn't do it u have a part failure and need to have the dealer test the system.

the power relay contacts are burned replace the relay

try the 10 minute re-learn:
put key in ignition and attempt to start, let off the key and leave in the run position for about 10 minutes or untill the security light goes out, shut key off and wait 5 seconds, attempt to start vehicle normally, it should start.

yes you have to get a GM pass lock harness the security, door chime, and a few other systems are run through the radio. the harness you need cost about $120 at your local car audio store.

try this: turn key on, crank starter for 1 second, leave key on for 10 minutes. after 10 min. shut key off and repeat 3 times. (on second try, crank a sec. or so longer, the reprogram may take off right away. if not, repeat make sure battery is strong, key could be on for 1/2 hr. sometimes engaging emergency brake before key is turned on prevent daytime running lites to come on to save battery power (if equipped). been through it, thought i'd mention it
