the ECU , reset on all cars has 3+ ways.
all do.
keyon
1: scan tool push reset button (best of best)
key off.
2: pull the ECU memory fuse for 5min put back,
3: pull battery neg lug for 5min put back.
4: Pull ECU, (gross way) but does 2 trick.

usa answers only... and not stated by you. (yours)
that fuse is called

ECM 30amp, F-3 (fuse relay box)
it is the memory fuse, and is hot all the time, (for memory retention)

ecu=pcm=ecm

What does code p2096 mean for 2005 magnum SE?


P2096- Post Catalyst Fuel Trim Sys Too Lean Bank1... It could be the result of bad gas or if you used fuel with a higher content of Ethanol. It could also mean that the post cat. converter O2 sensor on the driver side is bad. I would try filling up with a good quality gas (minimal Ethanol content), disconnect the negative terminal on the battery for a minute or so to reset the MAL (malfunction indicator light) and see if that takes care of it. If the code reappears, you may have a bad sensor, maybe ECU ECM PCM, worst case.... If you happen to need any info or ECU ECM PCM for this current vehicle (as they have a HIGH failure rate) or ANY other type of Car, diesel trucks small and big, SUV DIESELs ANYTHING etc, please call 888-672-4816 or 954-279-2040 and tell them Tim From FIXYA.COM sent you for FREE PROGRAMMING on YOUR NEW ECU ECM PCM DIESEL OR GAS COMPUTER!! Best Regards, -Tim

The service engine soon light will not come for pretest before starting engine. It is an automatic fail for emissions test. 2002 gmc sierra.


This could be something as simple as the Service Engine Soon light bulb being burned out. Removing the instrument cluster isn't too terribly difficult, but if you can carefully pull it out of the dash, look behind where the bulbs are located and see if that one happens to be burned out.
I hope this helps! :)

83-1 permanent dtc ecm relation failure


sounds like an OBD2 comm failure, mine (i have 10) all show comm loss. but.. can be blown fuses killing OBD2 DLC pin 16 (not 12v)
also, of your car is newer and the scan tool is older, it can fail.
newer scan tools work on all cars here. in usa. all, obd2 1996 and newer. (i build oBD2 gauges and can go endless here... comms...)

no Pxxxx code?
what scanner?, there are many. some are junk.
is this a USA car, when posting nobody knows,
in fact, cars up to 2006 world wide, don't have OBD2 ECUs/PCMs.
not posting where car was 1st sold , is a failure.
if you are in usa, we can access the online FSM and look this up.
we use.
alldata.com
or
mitchels.

lets back up. (a real scan tool not a funky useless code reader)
you, make sure pin 16 is hot.
you plug in scan tool (newer) if car has CAN buss? the tool too must be CAN BUSS CERTIFIED.?
you key on. not started.
you push the scan button, no comm fails, you see TPS throttle angle.
and ECT engine temp and air temp and RPM is 0
all that not started enigne yet, if you cant get there, wrong car, wrong tool.
if the engine runs, the tool must scan, if not pin 16 dead.
or wrong scan tool.

Ecm failure causes


no year?, hopeless.
my wild guess, cell; phone?
and 1983 Accord, with ECM flash code 13?

did you look here first then ask questions.
http://www.troublecodes.net/honda/

this is a Carb car right?
if car is EFI
13 means bad baro sensor, in non science terms
that means a bad MAP sensor.
the MAP is used to calculate all air flowing in to the engine
and this allows the ECU to inject a perfect fuel mix.
if 13 happens the eCu goes to limphome and sucks fuel like crazy.
13, means bad wires to MAP or bad MAP or bad vacuum line to MAP.
a tech, checks all 3, and then tests the MAP and the problem is solved. the FSM is free, ask.

really a 1983? very very old.... tjhat...

Code 601 EEPROM/PCM Problem what does this mean


ECM failures occur when the system ground is not reliable...those three hundred amp starts share the same access point as the ECM..."weld" themselves into position for a "brown out" condition that to the ECM makes them dysfunctional....a renewed ground attachment with takin' the 1/0 cable off and wirebrushing the spot where is was bolted in to establish reliable ground will make the failures disappear~

If inspecter find ECU scanned ECM/PCM failure -what happen to the car


Please be a bit more specific as iam having a job understanding exactly what you mean here ,inspected pro place what is this and as for low engine oil two months whats that got to do with a test and why is the OBDII being connected too as any test involves a gas analyser proble up the exhaust not connecting to the car via the OBDII idle a problem yes as this effects the CO emission reading but a welding mark? so what ,take vehicle to a local mechanic and get them to take the vehicle for the inspection they will know what to do and what is a pass and most likely know the inspectors and go for coffee with them -say no more They cannot fail a vehicle for faults stored in the memory thats for sure in any country ,no use a local mechanic and watch it pass

Hi engine cose error from eobd reader says code p2610 how do i solve this please or what is the problem manythanks


Hi there!

The definiton of your fault code P2610 is ECM/PCM Internal Engine Off Timer Performance

The only info I have relates to this being an engine management ECU (DME) problem. The info doesnt go into specifics but says that the car requires a software update, then further diagnosis if this is unsuccessful. Worst case would be DME failure.
