This shows things a little differently. One Leg to the lock, one leg to the CPU but not by the way of the TPRM

Enlighten us to what the difference is.

Also Dai is driving his car around and has called me to inform that everything works as normal with no issues at all.
So it really doesn't matter how differently the other thread shows it this is the best,fastest,no damage to car,the only draw back we found is we actually had to take to fuse out ourselves.

Hmmmm, feeling a little stupid here......

I tried removing the fuse box beside the battery, but after removing the battery cover, rain guard moulding, windshield glass/wiper molding, and attempting to lift the IPDM ER fuse box, I finally gave up! I couldn't lift the box high enough to either open it or disconnect the harness to it from below. Do I have to remove the battery first???

I'm new to this platform so I gotta ask, why are we fixing the steering lock?

wheee! 05-26-2012 09:17 PM

There are lots of threads on this, and you having an 09 should be very aware of this issue. Sometimes the steering locks fail and leave you stranded. Very hard to fix if it fails in the locked position, needs new parts from the dealer. Not great. Disabling the lock prevents the issue from occurring.

This is great news!

Vichtz 05-26-2012 10:25 PM

So this will remedy this problem? good news sans $500

As stupid as it sounds... what negative comes from disabling this? I mean, what does the steering lock really do, aside from lock the steering column...

Whee! and friends, GaleForce is correct. The "COIL" does receive power through CB#48.
The Throttle Motor Control Relay as a whole does not receive its sole power from CB#48 but also from CB#51 but the coil does receive its power from CB#48.

I am unsure what the coil is there for but when you remove CB #48 you will remove power to the coil of the Throttle Motor Control Relay. Attached is a thumbnail with circles for that little black dot AND arrows for tracing the circuit to the ECM for everyones viewing pleasure.

I AM NOT SAYING THIS DOESN'T WORK. I am just saying that GaleForce IS right and we don't know what signal the COIL provides at the ECM for both the Steering lock and the Throttle Control.

You are wrong too please learn how to read a wiring schematic.:shakes head::excited:

There is a tab that you push and the whole box comes out with the wiring harness attached then you can take the cover off and you should see the fuses.

Your diagram is incorrect. The only connection between the SLR and TCMR is an 80A fuse that feeds the 4 fuses. It is the ECM relay that has a relationship with the TCMR.

Confirmed by this schematic from the other thread. (Image credit to GaleForce)

You want to know what is funny is I work on cars for a living and know how to read a wiring diagram ,I wonder how many people that are looking at this truly know what they are reading.:shakes head:

No not you Ubetit.

I work on elevator controls for a living and these diagrams are truly elementary. Thanks for the find, i will be pulling the fuse today.

Your welcome:hello:

And thank you for reading the diagrams properly.:tiphat:
