Alarm problems & code 28
The alarm on my 1993 vette does not activate when i walk away nor does it de-activate when i approach.The ecm was recently remanned and the battery was not in the remote for quite some time.The code 28 says its a Quad driver module #3 circuit,what the fu#$, anyway it says check the resistance of the air conditioning clutch relay and the cooling fan relay coiuls,and to replace any relay less than 20 ohms,suggestions are welcome.
