Fuse box and Low Tire Pressure warning

[Paladine71]

Two questions for the gurus...

1) Does anyone have a fuse box diagram for the H3 Alpha (not sure if it's different from the I5 version)? I'm tracking fuse 27 for the air bags, but have no idea what the other ones are.

2) I've been back from Cliffs for over a week now and the Low Tire Pressure warning is still coming on at startup. How do I clear it? I believe in the past it went off after driving it for a while. And yes, my tires are fully pressured at 40 lbs. :roll:

The diagram for the fuse box should be printed on the inside of the fuse box cover (at least it is on my 08) but here is the fuse box layout (from the 2008 owners manual)

TPMS relearn procedure

 

[3rdH3]

The fuse box diagram is on Pg. 10-39 of my 2010 Alpha Owners Manual and there should be one on the backside of your fuse box cover also. As far as your TPMS problem, I would try reprogramming the sensors Pg. 10-55 Titled TPMS Matching Process which is also in your Owners Manual. I am not a guru. I just have read my Owners Manual. If you do not have one they are available online. I hope this helps.

I also have a PDF version of the owners manual that I can email you if you want.

James,
Did you do the TPMS relearn/reset thing?

a) Check tire pressure on all tires to make sure you are at over 38 psi in all tires.
b) Set parking brake
c) Turn on Key, then quickly turn headlamps on and off 4 times
d) 2 horn beeps sound to signal you are now entering the 5 minute calibration mode. The User Manual is wrong since the TPM ICON does NOT FLASH as documented.
e) Go to left front tire and inflate or deflate for least 10 seconds
f) Wait for beep to signal ready to move on
g) Go to right front tire and inflate or deflate for at least 10 seconds
h) Wait for beep to signal ready to move on
i) Go to right rear tire and inflate or deflate for at least 10 seconds
j) Wait for beep to signal ready to move on
k) Go to left rear tire and inflate or deflate for at least 10 seconds
l) Wait for beep to signal ready to move on
m) Turn the key to off to lock position - most people would conclude the reset should be done at this point.

Notes:

When you now turn your key back on and the DIC TPMS message is still there after all your hard work, the trick is you have to actually drive the vehicle before the TPM reset is finalized. The manual should at least note this requirement.

You don't have to touch the spare other that make sure pressure is up before you start.

If you take more than 5 minutes, you have to start over with the ignition off. If after all this, and the DIC message is still there, you might have a dead battery in one of your sensors.

You can also buy the OTC tpms tool - not cheap though - but if you switch rims and tires out every spring and fall for winter or for wheeling/road wheels yourself, it may well be worth the investment & will saves you a ton of time resetting the sensors using the above procedures and dealing with raising and lowering the air pressure or dealing with the dealership or a tire shop to do it for you.

Thanks, the digital image of the fuse box and relearn is exactly what I needed. 08, if you have a pdf of the manual, I'd appreciate it. I can't locate my physical copy. Had it out a while back and my wife happened.

Not a problem. Send me a PM with your email address and I will email it to you.

Actually, step #9 above is wrong (it is in the manual that way, but just another example of errors in the official print). Once you hear the last confirming chirp, I do not care what is on the display or not, the last chirp indicates it is finished and learned, turn the switch off and you are done.

You're right Doc. That's why I didn't post the instructions from the manual & posted ones that I had saved a while back and found out that they were more accurate than what was in the manual.

If it goes off after driving around or during a restart later in the day, and the ambient air temps have risen, it usually means the tires are a bit low and in most cases, due to colder morning temps. (Mine has turned on every morning since labor day, but go off in a mile or two.)

As for the SIR, this might help more if you are tracking internal fuse panel circuits.

Good point. I did see yours ended up the same as the way I pointed out the manual error, but too many times people will blindly follow the all mighty manual. I think we saved them. :huh:

GM service and owner manual information was written by outside firms such as Valley Forge, EDS, DAS, and a few others. I was always amazed not by how much they got wrong, but by how much they got right.

My wife works for a firm in Troy MI that used to print manuals for GM and VW, she did/does graphics layouts, and when she spotted something that was wrong (ie confusing, gramatically incorrect, conflicting with a previous statement, out of sequence etc.. ) she would contact the source and if a fix was not sent in before print deadline, it went the way thay got it. It is impressive how much they got right considering the wealth of information being processed.
