Help with CAFD files

[KingsleySmith]

Hi all. Long write up, but will make as brief as possible.

2015 M4 F83, current I-Step F20-19-07-539, shipped I-Step F20-14-07-503.

Car went into dealer for a faulty ValveTronic wire harness. Dealer updated the car hoping this would correct problem, prior to the harness being found bad. car was coded with no issues prior to going into dealer. When tech was done with work he stated that there were both L & R turn signal malfunctions. He had no clue how to fix.

So here is what I've found and done. VO coded FEM_Body ( after adding 5AP & 8S4 back in), KAFAS2, both TMS & LHM. And other ECU's I had previously coded. Trying to get car back to as stock as possible to start fresh.

Still have turn signal malfunction and no side marker lights.

Running ISTA I'm getting ECU with fault codes in STML for TMS_L, STMR for TMS_R. LHML for LHM_L, LHMR for LHM_R. FEM ECU for CAS. I believe the FEM fault is due to all the light module faults.

ISTA is faulting the lights as "LED's not taught in" with codes 805CF8 & 805E78. I've gone through the alignment procedure in ISTA and everything pass's fine.

When I pull up the data for the faulted ECU's it's giving me a tree coordinate that is conflicting with what is actually on the car. The items I can see that concern me are below:

ISTA info:
LHM2_R (LHM_R)
CAFD 000016BF_001.008.061

E-SYS info:
LHM2_R (LHM_R)
CAFD 000016BF_001.008.051

ECU is responding properly when tested in the troubleshooting portion of ISTA.

ISTA info:
LHM2_L (LHM_L)
CAFD 000010BA_001.008.061

E-SYS info:
LHM2_L (LHM_L)
CAFD 000010BA_001.008.051

ISTA info:
TMS3_R (TMS_R)
SWFL 000017EA_036.000.000
CAFD 00001083_036.000.002

E-SYS info:
SWFL 000017EA_035.000.000
CAFD 00001083_035.000.002

ISTA info:
TMS3_L (TMS_L)
SWFL 000017EA_036.000.000
CAFD 00001082_036.000.002

E-SYS info:
SWFL 000017EA_035.000.000
CAFD 00001082_035.000.002

All tree coordinates for FEM are correct. Currently running E-Sys v.3.27.1, E-Sys Launcher PRO 2.8.2_Build_162b BFU Edition with v.4.27.20_PSdZData_Lite.

Sorry for so long, just tired of pulling my hair out with this thing. Any help is appreciated. I do know when I look in my PSdZ file I do not have the CAFD files that ISTA is listing.

Thanks,
K

Did you do teach-in procedure?

You can recode them with E-Sys to stock and Run teach in procedure with ISTA. That should help.

[KingsleySmith]

Sorry been away on vacation. Yes I did reteach the headlights, that is not the problem. The problem is there are no front blinkers or side markers. Headlight work perfectly. The rear blinkers work fine, I get a normal 3 flash on display then a fast blink, yet no front turn signals. Digging into it further still. Does not really bother me, but wife hates it and won't drive the car.

I have also injected new CAFD with E-SYS, and still no blinkers up front.

When new hardware is installed or headlights are programmed. ISTA+ Teach-in procedure is needed. That will fix behavior.

[KingsleySmith]

Ok I'll give it another try. But nothing new was added to car that felt with headlight system. Only thing is dealer updated I-Step trying to correct a problem with valve tronic motor. Finger's crossed. Thx for help.

Check out https://www.bimmerfest.com/threads/g...ista-d.900732/, specifically the third image that is "initialize the headlight driver module."

[KingsleySmith]

Thanks. I'll give it a run in about a week. will be unavailable for the next several days. When I tried to run it yesterday I got a FEM error saying the blinkers where turned off. Wants me to code the FEM, which I've done several times, and still shows blinkers as being turned off. Frustrating.

K

[KingsleySmith]

No joy with initializing headlights. They start going through the test and then abort with a fault detected. Never tells me what the fault is. About ready to give up on this. Does not really bother me when driving, I don't like the fault showing on the dash though. Problem is wife refuses to drive car with non operational from blinkers. Thanks for the suggestions Almaretto.

So both lights fail teach in? When i had a internally disconnected parking light connector(3 amber LED corner light) on the driverside, the passengerside passed but the driverside failed teach in. Both Low beams still worked. Prior to trying teach in, i was getting STML sidemarker light open circuit. After trying teach in and failing, it no longer showed that msg anymore and instead showed LED needs taught in procedure.

Are the low beams working for you? During the teach in test, do you see any lights turn on and off? I would look into the repaired wire harness. Maybe something is disconnected or something.

[KingsleySmith]

Yes both fail teach in. During test they are on and move up/down and sideways. Headlights work perfectly when driving the car.

The wire harness is new, not repaired. It is the harness for the valve tronic motor, so not sure it has anything to do with the lights. But who knows with these cars what the harness's do.

The only lights I do not see on are the side markers and turn lights (front). At times I do get the side markers on when triggering test in ISTA, but they do not stay on. And they do not always trigger, but they do work at times during testing. Argh.....

K

Note: when running ISTA, when looking at the blinker test, I do see them activated when moving the blinker switch to left and right blinker. So it is seeing the signal, just the lights never come on.

My driverside corner light also worked when running the test but failed teach in. Since teach in wasnt completed, my front driverside turn signal and angel eye rings did not turn on during normal car operation(only low beam worked, they are controlled by a different module). The driverside corner light connector was not connected internally even though ISTA was able to activate it during the teach in... I think something like that is happening to you. Did they have to repair the wires on both side? i cant imagine both modules going bad at the same time unless they were shorted or something.

I spent a half day troubleshooting coding because i thought it had to do with my istep update since the corner light worked during the teach in test. After coding the TMS and FEM modules, it still didnt work so i explored the physical connections and found the connector in the corner light was disconnected. Had to remove the fender liner, then corner light module to the access the connector.

[KingsleySmith]

Pulled the fender liner out from the drivers side. Could not find anything disconnected, sure is a pain getting in there. Think I'll pull tire and get a real good look.

My angel eyes are working fine. You say only low beam worked? Did you highs not work? Both mine are ok.

And the wire "repaired" in question was not for the lights at all. It was the harness for the motor on the valvetronic servomotor.

My same thought, both going out at same time, doubt it. Just so strange it worked perfectly before going in for the valvetronic problem.

Thx for the suggestions. I'll dig some more tomorrow. Getting cold in garage.

K

[hC1001]

Very strange. Are the headlights and modules original to the car? I think in your case, its something to do with coding.
Have you tried "detect caf for swe", selecting the same istep version that the car is on and then code?

[KingsleySmith]

Yes lights are original, I'm first owner. Done the detect cafd, several times. ISTA keeps telling me a light is encoded incorrectly. I would think detecting and inserting a new cafd would overwrite any possible encoding error. I'm at my wit's end with this.

[Almaretto]

It is strange that ISTA and E-sys are reporting different software levels.

Have you tried Read ECU & Read SVT in E-sys to compare?

[KingsleySmith]

Yes I did, they match fine. Installed newest version of ISTA, and they now match as well. ISTA wants me to initialize new headlight driver module and teach in turn indicator.

Here's what ISTA gives me.

Fault description The STML has not been taught in yet.

Condition for fault identification Supply voltage between 9 and 16 volts.

Terminal 30 on



Condition for fault memory entry

Action in service Start teaching in the LEDs by means of the diagnostic function.

Note on effect of fault No light source is activated.

Driver information
Check Control message (122): Turn indicator, front left, has failed!

Check Control message (378): Side lights / daytime driving lights, left, failed!

Service instruction The headlight driver module can be initialised with the following test module:

Initialise headlight driver module.

And then for details I get a fault code of 805CF8, LEDs not taught in. Every time I try and get an abort with fault. Argh..

Thanks,
K

There maybe hardware issue.

CC-ID 122 – Indicator Front Right Failure & rapid blinking can suggest defective light bulb.
CC-ID 378 – Sidelight/Daytime Lights Defective- Left

[KingsleySmith]

The rapid blinking I get is from the turn signal indicator, inside the car. Lights never blink on the blinker. Prior to the dealer messing this up I had coded off the yellow side markers.

Would one defective blinker bulb cause both sides to fail? I have seen a flash of the side markers, at times, when running some lighting test with ISTA. But they never stay on for any length of time. Thx again.

K

[KingsleySmith]

Hey Almaretto,
What is the difference between flashing an ECU and detecting CAFD and injecting? Everything I can find is inferring that I haver a coding error in one of my ECU's, but unsure which one.

Pulled the turn signals/side markers yesterday and they are fine. These are LED BTW. Thanks buddy.

K

[hC1001]

If you have a 2015 M4, It should be TMS and there two(one for left and one for right side). You should have been coding the TMS modules.

[KingsleySmith]

I've VO coded it, injected CAFD from detection. Several times. No luck, ISTA still tells me I have a coding error somewhere. Want's me to encode the FEM.
