Cruise functionality on ECU?
Cruise functionality on ECU?
Hi All,
My friend bought OEM cruise control module from Japan and successfully install it on GE8 RS AT (Indonesian market). I did the same (exact wiring etc) on my GE8 RS AT as well but can't work. The only I got is "cruise main" led on the gauge turned on/off following the Cruise Main button on the steering wheel but accel/ decel button can't work. The only (noticable) difference between his car and mine is the ECU. Mine labeled with "TH" (Thailand manufacture?) whilest his labeled with "JP" (Japan?). Is there any functionality difference between those ECUs?
According to ESM, cruise CPU is resides in the gauge, but I've tried to borrow the gauge from my friend to put it in mine but won't work either.
I really appreciate any suggestion or anything that can make me move forward. Planning to buy HDS if necessary...
PS. this is my 1st post in this forum, don't be mean to me...

Hi sorry to raise this old thread but I am in the same situation. My fit/jazz is thailand built so would I need to swap the ECU aswell? Or could the HDS activate my ECU for cruise control? Please help. Thanks

Cruise control works now.
Just an update on this for anyone in the same boat. Check your brakelight switch that it is a 4-pin switch for cruise control. I made the mistake of not checking the pins assuming that since the car was prewired that it already had the 4-pin switch.

Hi, I am also planning to install cruise control on my GE8 AT. My Jazz is a Philippines version but built in Thailand. I'm planning to buy an OEM steering wheel control module with audio, cruise and paddle shifters. Is that all I need, or do I need to buy additional parts? Lastly, how do you route the wirings? Thanks!

You need the steering wheel with cruise control buttons. Make sure you get the clockspring unit that came with that steering wheel as it will have all the pins for each wire (airbag, audio, cruise, paddles, horn, swc illumination).
For my jazz/fit, it was prewired for cruise control (you can tell by looking at the brake switch (4wires) and the car side of the clockspring (3 or 4 extra wires)). Do the gauge/cluster test to see if your cluster has the cruise control lights.
If your car is prewired like mine then it is a very easy retrofit:
Replace the steering wheel, replace the clockspring, replace the brake switch with a 4pin version and your car is all set.

I got my thailand built jazz fitted with oem cruise control.

. I've tried to swap all my steering, brake switch, gauge, even ECU from my friend's cruise enabled ge8 (vice versa) and the last conclution is: My ECU doesn't support cruise... sadly... last week I sold my cute GE8... with all accessories and mods still attached. *waiting BRV*
Yes it's an easy retrofit... if your ECU support cruise...

Jazz/Fit 2nd Generation Cruise Control Wiring
On the same note, I have everything wired according to above schematic. Mine is 2013 Jazz CVT, right-hand drive. Cruise main comes on, but Cruise control doesn't engage. HDS shows me all button inputs, except the second brake switch, which is nowhere to be found. If anyone had this issue, please comment. The second brake switch should be normally open- that is when you leave brake pedal alone, it presses the switch, and sends +12 V to pin A41(the top ECU 49 pin plug). It looks like my ECU has CC disabled, but why would it then show all the CC switches inputs and outputs in HDS? Also, the transmission range input is called "AT Forward" in HDS, and is on when shifted to D or S.
Any help welcome!
