'96 LHS check engine

1996 Chrysler LHS - check engine light is on

From reading around, I turned the ignition key on 3 times to get the
blinks code.

I got: 1 2 7 2 5 5 -- but I don't know what the 1272 means, just that
the 55 is the end. I looked around some sites that gave OBD diagnostic
codes, but the 1272 didn't show up anywhere.

I'm also reading that there are some places that might hookup to the
computer and read and provide for me the actual stored computer diagnostic
information without charge.

Or, what is the best approach to this problem?

 

I have a Chilton manual for the car. It has a section called Driveability
& Emission Controls which has a table full of diagnostic codes expressed
in hex, MIL, generic scan tool, and DRB scan tool -- where MIL stands for
the check engine light on the dash and PCM stands for Powertrain Control
Module and DRB stands for Diagnostic Readout Box.

I can't make enough sense of the information I'm getting from the manual.
It says 12** indicates the battery being disconnected and 72** indicates L
front catalyst efficiency failure. Sometime last year the battery was
disconnected, but that was a very very long time ago, there have been much
more than the 50x on-off ignition switch cycles the manual says are needed
to clear the computer of a diagnostic code that no longer prevails.

I don't know about the cat efficiency code information. About 3 months
ago I replaced one cat because it had pieces rattling around in there that
caused concern that the junk might plug the exhaust system and I was going
to be traveling to Mexico and was worried about breakdown.

 

Don't worry about the code 12 as this is also a start of codes as well as
battery recently disconnected. The one you need to worry about is the 72
which is indicting your left catalytic converter. Which one was previously
replaced? I've never experienced this code before, but know that others on
this group will have some thoughts since I would think this could also be
caused by several other issues and not just a bad catalytic converter.

I can't recall perfectly, but it seems that it was the L one which was
replaced. I found the receipt for the work, but it doesn't say the side.
Tomorrow I'll give Eddie a call and see if he can remember.

How about the question about whether or not there is some way to get a
'real' readout from the computer instead of just the blink codes?

 

You need an OBDII code reader ... The blinking codes was a huge asset that
they stopped doing sometime around 1999 or 2000.
