What is the ASR error code?

[masayoshi]

hello. The ASR lamp turned on and the accelerator response was strange, but after turning the ignition on and off several times, it is now working normally. When I checked it with DAS, there was an error of 014 Control module EFP N4 / 1. I have searched every error code table but there is no mention of this "014". Is this a malfunction of the E-GAS itself? I wish I could check the impulse code as well, but I only have DAS. If anyone knows, please let me know.

I don't know the specific answer, but sometimes DAS will show a code that doesn't exist in the manuals / documentation. EFP = E-GAS = pin #7. If you have access to a different E-GAS module, try swapping it out. Were any codes present on other modules?

Also, obtain the items needed to check impulse codes as well. You need those to check SRS and HVAC codes anyway; DAS/HHT-Win cannot check analog codes from those systems.

Thank you very much. There were no other errors in the diagnosis of DAS. The vehicle is currently operating normally. Immediately look for a spare E-GAS. Thank you very much.

Hello.
The car ran fine for a while after that, but then the ASR light came on again and it went into limp mode.
I diagnosed it again with DAS, but it is the same "014" error as before.

After turning the ignition on and off several times, the ASR light goes out and returns to normal.

I watched the EFP live data for a while to try to determine the cause.
The accelerator pedal is not touched.

09 Idle speed safety cont. M16 / 1S2
10 Safety contact M16 / 1S1

may turn ON / OFF independently about once per minute.

Of course, S29 / 3 remains OFF.

Is this a malfunction? Or is it normal?

If it is a malfunction, do you think the ETA or the E-GAS is at fault?

 

[gsxr]

I am not sure if ETA switches M16 / 1S1 and M16 / 1S2 normally switch once per minute or not. Was this with engine running, or engine off?

If the ETA is not a known-good unit (either low-miles late-datecode, or rebuilt by a competent shop like Don Roden in USA)... I'd be more likely to suspect the ETA. Failures of the E-GAS module are pretty rare and they tend to fail "big", i.e. go completely dead. Still, if you could borrow a different known-good E-GAS (from 400E, R129 or W140) that would be an easy test. If you get the same issues with a different E-GAS module it's very likely to be the ETA at fault.

Thank you. I would like to investigate a little more.

The switching is a malfunction of the HHTWin system.

Error Code 14 is listed as a defective N 4/1.

But I‘m quite sure it is the ETA itself that causes this problem and not N 4/1.

Thanks for your comment. I did some research after that. First, I disassembled the ETA. The harness has been repaired and is clean. The potentiometer is not worn or anything, the live data from the HTTWIN potentiometer looks good, and I thought the ETA microswitch was suspicious because when the ASR error occurs, it always occurs at startup after warmup, not while driving. So we applied contact restorer to the microswitch, and after that the ASR error did not occur at all. However, I think this was just a coincidence. Fortunately, I will be able to borrow a normal E-GAS and ETA from a friend at a later date. Now the error has not appeared yet, but it will probably appear again, so I will try to replace it with a normal ETA when the error occurs. I will report back with the results.

Did you ever correct the issue? What was the reason?

I then replaced it with Don Roden's ETA, which has solved the problem so far.

However, once again I had an ASR error, but this time the error code was 009, which I had never seen before.

This error code seems to be a safety relay and I exchanged emails with Don Roden and he said it was probably the E-GAS module. I was going to report the problem here when it was resolved, but then the error did not occur at all and I completely forgot to report it.

Don Roden is a great person to deal with and answer questions.

If fault code 009 was on the ASR module (pin 6), that is related to the ASR pump itself: "ABS/ASR hydraulic unit, right rear axle solenoid valve (A7/3y4)"

If fault code 009 was on the E-GAS module (pin 7), that appears to be "Vehicle speed signal (VSS)"...?

I doubt either would be related to the E-GAS module N4/1.

Thank you very much.

I am using star in Japanese and it is an image from the internet but this error.

I looked at the efp section of my code table and it says safety relay for efp/tpm/llr control unit (N4/1).

Ah, interesting. If there are no problems with engine operation or driving (normal power, no limp mode, etc)... I'd ignore the code.

The WIS documentation is less clear on E-GAS fault 009:

I have seen this error many times and it was always ETA related. It happened at operating temps when the ETAs internal clutch coil heats up and fails temporarily.

There is a clutch coil error code on the EGas code list but the control module always choses to throw the EFP faulty code instead of clutch faulty code. Best way to know for sure is to grab a multimeter and measure resistance at pins 10/11 or 12/13 (depending on plug style) at the ETA plug. Cold coil is around 4.5Ohm. As it heats up it may go over 5Ohms but if its opened you have your problem.

Clutch coil is made of 0.035mm clear-coated wire winded up 420 times around the plastic core and then crimped at both ends with 0.5mm2 red and blue leads. That crimped connection is a weak spot that fails sometimes and causes limp mode. Problem is self-curing when the coil cools down.

ああ、面白い。エンジンの操作や運転に問題がない場合 (通常の出力、リンプ モードがないなど)... Id はコードを無視します。

WIS のドキュメントは、E-GAS 障害 009 についてあまり明確ではありません。

Thank you very much.

The error code table I have may be wrong. Either way, it has only appeared once, so I would like to wait and see how it goes for a while longer.

It could be a bad coil.

I would like to measure the current normal condition and measure it again the next time an error occurs.

The problem is that once I got the error when starting the car and restarted it immediately, the error stopped that time.

If it was always there, I could measure the resistance.

Please let me know if this happens again.
