I decided to check the codes on my car for the first time.. I don't think they have ever been cleared since the car was new... there is a ridiculous history... I will list them all and try to decipher what each of them is and what happened to the car.. and most importantly look at the current issues not in history.

TCS
C1226 H - LF EXCESSIVE WHEEL SPEED VARIATION

BCM
B0432 H REAR DEFOGGER RELAY CIRCUIT.
B0503 H RH DRL RELAY CIRCUIT
B0508 H LH DRL RELAY CIRCUIT
B2483 H BACKUP LAMP RELAY CIRCUIT
B2528 H HORN RELAY CIRCUIT
B2592 H COLUMN LOCK/UNLOCK DRIVE (B).
B2723 H PASS KEY DETECTION CIRCUIT.

A0-LDCM
B2282 H BATTERY #1 FAULT.
B2284 H BATTERY #2 FAULT
U1064 H LOSS OF COMMUNICATION WITH BCM.

A1-RDCM
B2283 H BATTERY#1 FAULT
B2285 H BATTERY #2 FAULT
U1064 H LOSS OF COMMUNICATION WITH BCM.

A6-SCM
B0851 H
B2605 H
B2607 H
B2606 H
U1255 H SERIAL DATA LINE MALFUNCTION.
U1160 H LOSS OF COMMUNICATION WITH LDCM.
U1016 H LOSS OF COMMUNICATION WITH PCM.
U1064 H LOSS OF COMMUNICATION WITH BCM.

RFA
U1096 H LOSS OF COMMUNICATION WITH IPC.
U1064 H LOSS OF COMMUNICATION WITH BCM.
U1016 H LOSS OF COMMUNICATION WITH PCM.
C2115 H LR TPM SENSOR MALFUNCTION.

Currently the only issue I have is a random TCS/ABS/AH error that happens after I hit a bump hard or something... happening more and more frequent lately.

Okay, I added all the definitions of the codes.... I just replaced the battery in the car because it was screwed up.. had a bad cell or something.. new optima in the car now. One of the problems that has plagued the car is the remote is screwed up. If I walk ANYWHERE near the car, it starts locking/unlocking itself constantly... I think the whole damn reason the battery got messed up was because I left my FOB on the keychain by the garage, and it locked/unlocked the car to death... Could ALL of these codes by cause by a bad remote? Would it cause the BCM to think it's screwed up? Looking over the codes.. it appears the real problem is the remote, as it has loss of communication with every damn thing on the car.. and everything it lost communication with has all kinds of problems.. I have no check engine light at all, which I would figure a bad BCM would cause.

any idea? Also, what causes the C1226 code? That's the whole reason I got started on this.

 

You already started this here:

You shouldn't start a new thread like this .... however .... what's done is done.

First, I'd go through and clear ALL the codes in all the modules so you have a clean starting point for diagnostics. Uxxxx codes are relatively common, and for most of the others .. well who knows when they occured and/or were fixed.

Second, n your original post I replied that you should check for stainless brake lines on the car. Hitting a bump and getting a C1226 is (or any other wheel) a common symptom of a SS brake line issue. Check what brand is installed and POST THE ANSWERS IN THIS THREAD.

HTH

 

I know this is probably a dumb question, but have you moved the slider to passive on the fob so it will not lock/unlock the car if you're near it?

 

Yea,,,that is commonly known as MON AND POP posting. Ask dad if its all right to take the car. When he says NO, you ask MOM the same question to try to get the answer you need!

Yep,,,I have to agree, follow the other post!

Clear ALL of the codes and get a new starting point. Then we can follow the new codes to the problem.

The "H" after the code means "History". As in it happened before, theres the record, and it's not occuring anymore.

I also pulled about 14 codes from mine after I changed the battery. Thats where a lot of your loss of communication and battery faults were coming from.

Clear them out, everything is fine. If they come back, then you can start diagnosing it individually. But because the "H" is there for ALL of them, I highly doubt they will return. Mine haven't, but I didnt have any TCS or BCM codes either.

 

 

The other thread did not pertain to the new questions involving the FOB.. out of 25 codes, 1 of them pertains to my previous thread, that is why I started a new one. I think the criticism is ridiculous and out of line.. I would expect that on a mustang forum, but not here.

The car has factory brake lines, not aftermarket or stainless. The PCM/Main frame ground looks to be good, and I'm not getting much of any resistance off it. the wire harnesses look to be fine... I did however discover that wheel was bent.. could a bent wheel cause a wheel speed sensor malfunction?

 

That is an issue I've noticed... I remember hearing about this some time ago. I did slide it back and forth aggressively and it completely stopped doing it.. but after the battery dies or I'm not near the car anymore, it will start doing it again. What is the deal with the active/passive switch? is it a problem? Does anyone have a board layout for the FOB? I can probably replace the bad switch/circuit on the board pretty easily.

 

If you have it switched to passive mode, there should be no response from the car when you're near it with the fob. If there is, you may have damaged fob.

 

looks like it's damaged.. must have been the 5 times through the washing machine, and once I flew off my boat into the lake with everything I owned.

 

OK, that's smart ... post questions and don't give any pertinent info .....

"I'm having a problem with my fob (been in water several times) .... DUHHHHH ... maybe an electronic device doesn't take well to water ????

I'm having a problem with a wheel sensor (I whacked the wheel so bad I bent the rim) ... DUHHHHH ... maybe I damaged the wheel hub (which contains the sensor)???

When you start a post and say ... "Currently the only issue I have is a random TCS/ABS/AH error that happens after I hit a bump hard or something... happening more and more frequent lately." and then think people think this is a question about your fob ??????????

You're a flake

 

Chill man. This a forum...he was simply asking a question. Gheezzz

 

And gave obviously stupid questions and answers ...... look at the following quote from his OP

"Currently the only issue I have is a random TCS/ABS/AH error that happens after I hit a bump hard or something... happening more and more frequent lately."

Then compare that to his statement "The other thread did not pertain to the new questions involving the FOB.. out of 25 codes, 1 of them pertains to my previous thread, that is why I started a new one. I think the criticism is ridiculous and out of line.. I would expect that on a mustang forum, but not here."

I tried to help him out ... he wants to get his panties in a twist about it, that is his (and obviosly your) problem since you (and he) apparently can't read the entire post.

 

man, shut your face, I don't need your immature **** in my posts, grow up.

 

I agree! Geeze...do I have to stoop to this idots level to get him to STFU. Maybe he was beat as a child...or not beat enough. What a turd.

 

A dead or low battery really messes with the systems on these cars. It will cause all kinds of codes to fly. Like Bill said, clear them out and see what comes back. But remember, if your battery ever goes dead it will probably fill them right back up so remember to clear them again.
