My brother has a 98 Accord Coupe with the F23A4 and an Automatic Transmission. We found that the 2003 CL Type-S Shifter assembly fits nicely into the place of where his stock shifter was, and with minor odification works flawlessly. But since the TCU on his car is different from a CL type-s (obviously) we had no use for the Steptronic or whatever Acura Calls it's Manually selectable, Automatic transmission. So we decided that we would use the input to drive a +/- a track on his CD player. However we are having a hard time finding a wiring diagram so we can controll the head unit he has. If anyone has a wiring diagram for a 2003 CL/TL type-s shifter it would be verry appreciated

 

damn, thats original, ive never heard of that before....if you are doing what im thinking you're doing, when you shift the gear lever into steptronic, will the car come out of gear?

 

No the selector itself it a straight forward and back type of application, pulling at a bowden cable so when you slip it into steptronic it is still in drive, but a switch signals the TCU that it is steptronic mode and not to switch gears until a certain criteria are met... so it works the same as a regular shifter, you just have to remove a pawl keeping the lever from going from neutral to reverse, because a CL is speed dependant and an accord will only actuate the Parking lock when it is in park and the brake is depressed. it will work on any 98 accord, and I'm willing to bet that honda uses the same system on a lot of cars... it's just trial and error. my bro has pics, I'll see if he can e-mail me so i can post for others to see

 

there is a picture, and I'm doing the mod. I was out in my car so my brother was nice enough to post it.

 

Bump

 

I would also like to know how this works. Maybe you could give a draw out a diagram or something like that?

 

are you talking about the shifter assembly swap? or wiring the + and - of the steptronic to my deck?

the shifter assembly is simple enough, it pretty much fits right in where your old one is, and it obviously looks much nicer. you have to do a little modification to get it to work, but it's easy.

the way the steptronic works, it's all electrical. when you go to + or - it doesn't change anything mechanical it just sends some kind of signal to the ECU that tells it to upshift or downshift. I am trying to figure out what kind of signal it is sending so I can change that signal to the same kind as the + or - on my deck so the deck believes it's getting a signal similar to the steering wheel controls, and changes the song.

 

Thats a nice mod but I believe the 99 TL's would be more beneficial since we dont have 5 gears. The 99 is 4 gears like ours but harder to find. If that works out for you then write a writeup please.

Sorry I cant help on the radio wiring though.

just is the a Q'?

i know in the 98 accord you can shift like a manual trew 1,2,D3,D4, but the catch you cant shift down to 2nd and first. you have to come to a complete stop before so.

Sometimes i use the D3 and D4 and a low and high gear when im turning corners.

what im wondering have you tried to like go from first to second, then to D with + and - to shift back down and up while driving, or does it work from like -,-, back to first then +,+ to third?

if this doesnt work, if you look at the pins at the tcu and the shifter and compare them to see if some are missing. then see if you can get the shifter wires that came with the shifter and hook it up to the main system. then try again

it meight be all the same system withend the tcu, but honda cheated us out and gave us the simple verison to play with and gave acura the fully loaded one.

just a thought..

 

how would you rig it up so that the accord TCU still reads the shifter in D.....id think as soon as it left D, it would no longer recognize the car in drive, and therefore it would be impossible to use the +,- for messing w. the stereo

 

is there any wires the come from the + /-? theres gotta be some kind of sensor.. if you have the stearing with audio controls trace the wires from the audio controls back to the system harness. from the harness add wires one for the + the other for the -. You could tap into them using wire taps. now run those 2 wires under your counsel to the shift sensors




i hope that made sense, i duno if im even answering your question. if you dont have the audio controls on the steering wheel to trace back to the harness, maybe some one has the diagram to see which two wholes in the harness you can plug wires into to contol it..

 

oh yea this also might be dangerous becuase shifting an auto while driving is always a danger and it might mess up the transmition or blow it if you slipped and shifted into the wrong thing..wouldnt it?

 

I have already done the actual shifter assembly install and it works flawlessly. the way that our shifter assembly works is that it only uses 4 wires as opposed to the cl-s that uses quite a few more. the way our shifter actually shifts is mechanical. the cl type s works the same way, with the exception of the steptronic. the steptronic is completely electrical. What I am trying to figure out is what signal is sent out once it tries to go up and down, then i want to change that signal to a similar signal to what the steering wheel audio controls use when you press up or down, that way it will emulate the steering where controls.

 

did you understand anything i sayed?

 

I did understand and that's where we are right now. I have to find out what kind of signal moving to the + or the - is producing, thats why we need a wiring diagram so we can figure out which wires to test and what kind of signal they are putting out.

 

well i think all it is is an electrical current.. your could get a meter of sum sort tap into the wires that are connected into the steering wheel controls and see what the output of the current is.

 

shadow,

You dont have to come to a complete stop to shift into 1 or 2. YOu can do it from a roll. You just have to be in the right mph and rpms. The computer doesnt do it cuz it knows if it does it gonna go BOOM! 1st max's at like 40 and 2nd at like 55-60. If you cruise in third and doing like 50, you can shift into 2nd and it'll drop down a gear to second. Just be reasonable. The computer is smarter than you thats why it doesnt downshift.

dj14,

thats a badass MSPaint!

djp,

So even with the newer assembly and no marked first gear does it just workt he same? Like d2 is 1, d3 is 2, and so on...? Just simply substitute correct? I was thinking the computer would read it as a 4 gear selector since its 5.

ture, but only times i really "needed" to do this is near death accendents. Some times the tcu is always shifting to keep the rpms down and save gas, but its a pain when there's this 18 wellier turing on my side on a left turn. I lucked out last time the tcu shifted down for me and i get out of the way.

here's kinda off the topic but what ever happend to that "S" light the older accords had?

didnt hold the rpms higher somthing?

 

on the cl type s shifter assembly instead of 1,2,d3,d4. they have 4 different options 1&lt;&gt;2, 3, d4, d5. if you move the assembly to the left it is in 1st, but it's the same deal as the steptronic, it's all electrical, not mechanical. the linkage sees 1&lt;&gt;2 as 1, 3 as 2, d4 as d3 and d5 as d4. I hope that makes since. What I want to find out is the exact wires that control the steptronic, I would assume it just makes a circuit, but I want to be sure. I guess I could just be less lazy and ohm out every pin, it's just hard to get it since it's already installed in my car.

Pictures of it installed in my car.

 

from the looks of it, you have an alpine head unit. Find out if the head unit does accepts a wired remote, if it does, then you are in luck. I wouldnt try hacking up your face plate/head unit unless you have a lot of spare time and the wiring diagram for that alpine head unit. IF you had the stock accord cd player, that would be an easy fix. Good luck

 

I have the 9853 and I read that it does accept steering wheel controls which is one reason I spent the extra money to get that specific deck.

 

no one has a wiring diagram?

 

I went to acura and got a wiring diagram. from what I can tell all I have to do is isolate the circuit and I should be able to wire it pretty easily. if anyone wants a DIY tell me. i'll probably post one up on v6performance.net pretty soon.
