If you have a pre-1996 Metro and the "Check Engine" light on and would like to find out why, you need to access your fuse panel and look for the diagnostic port. Insert a spare fuse into the port and then turn your key to the "ON" position. The check engine light will then blink a 2 digit code over and over. It may display more than one code also. Simply count the flashes for the code.
Example.........

1-2 (Code for no faults found)

This is a picture for the diag port connection...........

If your Metro is 1996 or newer, then your car is equipped with the OBDII system and will require a scan tool to get the code. Please note that most local parts stores will scan your OBDII system for free and if you go this route, please make sure you get the actual code # from the scanner. Here is a list of all 1996-2001 Diagnostic Trouble codes..................
