Chrysler OBD1 Codes

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

Within a period of 5 seconds, cycle the ignition key
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:
Chrysler OBD1 Decoder-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.
If you find some difficulties on doing this, you can take your car to
Auto Zone parts store and they can scan the code FREE for you. They
do this to encourage you to buy parts from them. However, don't buy
anything just yet till you confirmed the code with ATS. When you become
a member, we will show you the tests on the codes so you don't have to
buy unnecessary parts. Complete instructions will come with drawings and
wiring diagrams.
