Story book of trouble codes

[jdelarmente]

Anybody ever have this? Here is the list p0720,p0722, p1000, B1318,B1681, U1262,B1876,B1342,B1676,U1130,B1794,B2172,B1201,B1676. He then cleared them and then some cam back and they were these C1175,B1318,B1681,U1262,B1676,B1342,b1676,U1130,b1676,B1794,B2172,B1201,B1676. It's rediculous how many came up and I hope the PCM isn't bad.

Smells like scrambled eggs to me, if you dont know the ECU is in the trunk on the passenger side fender wall.. I'd start there and bring some salt and cheese..

You couldn't be much more wrong on that!

Where is the ECU/PCM depending on what ur working on it goes by those two names? I have access to alldatapro but I had my computer with all my other stuff shipped to japan cuz I'm leaving the states in April. So I have just an itouch to do all my surfing.

 

[willsull80]

Then what is back there? its a big aluminum box with large plugs in it?

 

[jdelarmente]

It may be the tranny computer some vehicals have seperate computers like a HMMWV i used that cuz I work with military vehicals more.

 

[willsull80]

I just pulled it out, its called a REM Rear Electronic Module WTF is that for?

It's rediculous how many came up and I hope the PCM isn't bad.

Let's just worry about the ones that came back for now.

C1175 - left rear wheel speed sensor or wiring to it.
B1318 - battery voltage low (You should take care of this first, it might be causing some/most of the other codes)
B1681 - PATS transceiver module signal is not received by the PATS control. This DTC can be caused by circuits between the PATS transceiver and the PATS control, the PATS transceiver or the PATS control.
U1262 - Electronic parking brake module bad comms (this is 99% certain to be because of low battery voltage)
B1676 - Battery voltage out of range (again with the low voltage)
B1342 - FEM internal defect (correct the battery voltage before you go further.)
U1130 - Bus comms problem
B1794 - Headlight low beam circuit failure
B2172 - fuel pump safety (crash) switch open
B1201 - fuel sender fault

You need to fix the battery/electrical voltage problem first. All those B1676 codes are trying to tell you that the voltage is too low for the other self diagnostics to work correctly. Fix the voltage issue, and most or all of the other codes may go away.

Some charts for you...

Joe's the freakin' man, man. :Beer

I just pulled it out, its called a REM Rear Electronic Module WTF is that for?

It controls the fuel pump, the rear lights, the locks (other than the driver's door), the rear windows, the fuel level senders, the battery saver relays, the rear defroster, rear seat heaters, and a few other things.

 

[willsull80]

OK cool so thats why my car is always a pain and only unlocks the drivers door when I put it into park... Is there a way I can make all the doors unlock when it goes into park?

 

[Lincoln Jealous]

that looks like a bunch of lottery numbers, maybe we should play

 

[jdelarmente]

The battery is new and so is the alternator. The battery is an optima and it's 3 months old. Alternator is brand new. Wow I wonder if this is why my car was running :q:q:q:qty when I would floor it.

Yes, if you're handy with a soldering iron and can do some assembly language programming.

Please measure the actual battery voltage, both with the engine off, and with the engine running. Then we can proceed from there.

Well 3 bit integers (Check) Soldering Iron (Check) Wiring schematic (no check)

 

[jdelarmente]

Batt voltage when off is 12.23v I never got a chance to check it when running.
