Scotty any ideas on how to check obd1 codes on my '90 5th avenue?

How to get the code/s for Chrysler 1983-1995 vehicles:

Within a period of 5 seconds, cycle the ignition key
ON-OFF-ON-OFF-ON.

  1. Count the number of time the MIL (check engine lamp)
    on the instrument panel flashes on and off. The number
    of flashes represents the trouble code. There is a short
    pause between the flashes representing the 1st and 2nd
    digits of the code. Longer pauses are used to separate
    individual 2-digit trouble code.

An example of a flashed DTC is as follows:

-Lamp flashes 4 times, pauses, then flashes 6 more times.

This denotes a DTC number 46.
-Lamp flashes 5 times, pauses, then flashes 5 more times.

This indicates a DTC number 55.
DTC 55 will always be the last code to be displayed.

Here's how your ignition key looks like. Make sure to cycle
it between on and off positions only.

Clearing codes can be performed by turning the ignition off
and removing the negative battery cable for at least 1 minute.
Removing the negative battery cable may cause other systems
in the vehicle to loose their memory. Prior to removing the
cable, ensure you have the proper reset codes for radios
and alarms.
