Is the replacement of an ECU in a 96 sable straight forward? I just bought a 96 sable for a great price. The only thing is that it needs a new ecu. The stealership wants $800. I currently have a 96 jetta and the replacement of the ecu simply involves removing the rain tray and accessing the ecu compartment. I have looked into it a little bit and believe the ECU in the 96 sable is underneath the dash (where the fuse box is) and that I would just have to lower the ecu and swap it out with the new part. Then I'm assuming I'd just need to clear or reset the computer/CEL codes using a vag-com. I am semi-familiar with the mechanical parts of the car but just do not want to spend the $800 at the stealership. Any ideas?

    I've been checking around abouty PATS and have found some info and technical pages. It appears that the 96 sable has PATS but it is the first version (version A)



    I took a look at the link below and it says that replacing the PCM there is no special action needed.



    Right at the top of page 12. So and I know you guys have been so much help. As I've read these articles it appears that PATS is a seperate module located in the steering column and that with version A of PATS I could replace the ECU without any nessicary reprograming. Also it mentions Service Card software. Is this the same thing as a VAG-COM reader?

1996 is the beginning of odb II when all the manufacturers had to start calling things by the same names, more or less. the ecu became the pcm, powertrain control module. physically installing a new one in your sable is about as easy as you describe. i can give you the step by step. if it really is a new one, you should not have any problems. if you use one from a junkyard it might not go so smooth. i don't know when ford started using vin matching, but it can be nasty. ok, here's the procedure i found:
1.disconnect battery negative cable
2.remove cowl deflector
3.remove engine wiring harness ground cable from the dash panel
4.remove the pcm electrical connector
5.remove the mounting nuts
6.remove the pcm
and then to reinstall
1.install the pcm in the dash panel. tighten the nuts to 71-106 in-lbs
2.install the pcm electrical connector
3.connect the engine harness ground cable
4.connect the negative battery cable
hope that helps

If the car has PATS, you have to have the dealeship program your keys to it, or it won't start. it's in the dash above the glove box, the connector goes thru the firewall and is fastened in with a 10mm bolt

My 96 prelude keeps shutting off when hot. What do I do to fix it?


96's are kinda the bad year for our cars being the only obd2 4th gen preludes so for any codes over 43 you have to look it up in the '97-'01 manual. Code 65 is "Secondary Heated Oxygen Sensor Heater Circuit Malfunction (Sensor 2)". Probable causes are an open in the secondary O2 sensor heater circuit or bad ECU. Have you tried resetting the ECU to see if it comes back? If so, you could check for loose wires coming from the secondary O2 sensor in the cat converter going to the 4 pin connector, or if you have access to another ECU I would try to substitute a known good ECU to see if that clears it up. The troubleshooting flowchart is on page 11-79 in the '97-'01 helms manual, and involves checking resistances and for continuity.

I think this could be the code I had on my '96 when I bought it. I tried replacing the secondary O2 sensor, and long story short it was the ECU. Luckily my '96 was still under the extended emmissions warranty, so Honda replaced it for free. I don't think you would be covered under the extended warranty because it was 14 years and under 150k miles. I just barely made it (within a month or 2 and 3k miles) last year.

As far as the engine sounds and rough idle, you could just need a valve adjustment. The secondary O2 sensor just checks the cat to make sure it's working right.

And all auto trans want to move forward when the brake is released.

My 2003 lancers airbag has been deployed. I have a new ecu, clock and airbag. what is the procedure for reinstalment?


It is pretty straight forward remove the old bags take note of anything removed and how it sets. line up the clock spring install the new air bags and then the ECU. If you install the ecu without the bags and turn the ignition on you will set the SRS light off again and need to get it reset so avoid doing so.

Fabia 1.4 MPI ECU problem?


I really doubt that the problem is the PCM (ECU), that is the least likely thing that would cause these codes. The causes will take a factory manual and good test equipment that can read live mainstream engine and sensor data.

No fuel new pump 93 jeep


If the check engine light does NOT come on when cranking, at the times when it won't start, and the relays are clicking and buzzing, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. ECU is likely going bad, causing the delayed start problem typical of early 90's jeeps. Reasonably priced repair or replacement services for your jeep ECU are available on ebay.

I have a 96 jeep grand cherokee laredo straight 6. I have replaced the battery and the distributor and cap. Starter has been tested and they said it was fine. We have been having issues with it dying and...


Cranks ok, won't start.
no spark at coil. ! main HV terminal.
checked fuses, no. (that be FIRST)
scan the PCM/ECU, no. (call it ECU from now on)
hopeless lacking scanner but... ok we try,,,,
if the fear of scan tools is so bad, then you get to do it the hard long way. okay.

The ASD relay runs this show, (fuses MUST TEST GOOD)
rule 1, the ASD most close, at key on
the ECU closes the ASD for 2 seconds. to start engine.
if not the ECU sees errors (asd can drop cranked or running)
there are 1 to 8 errors, on this car less, but still many.
if throwing parts blind is good, then new ASD relay?
test 1:
turn key, hear the ASD click we use a stethoscope to hear it.
2 man test, due to 2 second rule.
it must click or its is bad, or lost power to ECU. (fuses) or other power feed issues to ECU. (key switch bad)
what we do , if our scan tool was stolen, (haha) we
measure all 4 ASD pins at the 2 second rule.(a voltmeter)
and the 4 voltages tell 4 things
ASD ok or not OK
or ECU never once turn it on, (more work, lacking scanner)
lots.

http://jeepdied.com/ASD.html

those are the ropes.
fixing cars lacking a scan tool, is like the most hard thing to do.
I can do it, but I have vast tools in my shop.
Even a voltage data logger.... to monitor all ECU pins.

The ECU is just logic, if the inputs are wrong so can outputs.'
GIGO it's called. Garbage in , Garage out.

Starting problems at times


The ECU is the computer that, among other things controls electronic fuel injection on your jaguar (great cars).
To test the ecu you need equipment that is not normally for sale for home repairers.
You need to go to a garage, they will connect a flow meter to your engine and computer machine to your electronic board.
Here is something about ECU testing, just for general knowledge information.

Here you can buy replacement ECU, ECM and ECC and check spare price, just in case.
