SH 150 DTC 29???

[valyo]

Hi there

I own a 2007 SH 150.

Several days ago it just wouldn't start. After several hours waiting, it did start normally, but DTC 29 appeared (2 long blinks followed by 9 short ones).

I just couldn't find any info about this specific DTC.

Any ideas?

Thanks in advance.

Hi Valyo,
If you use the "Search" function with different key-words......I know this has been discussed in many different posts in the past.
I found this one for instance: (Scroll UP for chart/image)

Good Luck!

Thank you, TommyXP!

It seems that the problem has to do with the IAC valve - maybe some loose connection or valve failure.

Where can I find it?
or
Can anyone send me a repair manual (so far couldn't find throughout the web)?

Thanks in advance!

Due to copyright issues you will not find a "Honda Factory Service Manual" on the 'web'.....
Search e-bay or others.....
Good Luck!

Youre not gona like this....
From the sm;

MIL 29 BLINKS (IAC VALVE)
1. Recheck MIL Erase the self-diagnostic memory to reset the ECM (page 5-8****or my previous post as mentioned above****).
Start the engine and let it idle.
Check that the MIL blinks.
Is the MIL blinking?
NO - Temporarily failure; the system is normal.
YES - Replace the throttle body/ECM assembly with a new one, and inspect again.

[edit] apparently the IAC valve is a non-servicable part included in the throttle body/ecm, ik know that if you do take it apart you can definitly toss it in the bin as opening the valve ruins the calibration.
