Re: ERROR CODE 53
Well, I'm taking this directly from the 1990 Chevrolet Service Manual:
Code 53: System Over Voltage
This code indicates there is a basic generator problem.
Code 53 will set, if voltage at ECM ignition input pin is greater than 17.1 volts for 2 seconds.
Check and repair charging system.
I'd say have your alternator checked out. And wires too. Just a starting point. Hope this helps.
