Cruise Control Setup

Recommended Posts

Dear Technical Support

I use G4+ Fury in 1JZ-GTE VVT-i with new E-Throttle. Everything is pretty good. But I try to install cruise system with original switch form Toyota. I use Analog Volt to define the buttons and also use DI for brake switch. All button defined perfectly except ON button. The cruise status not change to Active. What wrong?

please suggest me

Thank you very much

Hey there, 

You'll want to check the output of the AN Volt signal when you have the ON switch turned on, and see if it matches the Analog Voltage thresholds table in the cruise control setup menu. 

By default the ON button is set to 0 volts, you might find that the toyota switch outputs to 0.5 volts or something like that instead when the ON button is pressed.

Hi Davidv

Actually I used Switch that has ON output is 0 volt and I already set in An Volt to 0 volt also. But when I press ON button, nothing happen.

For more information, I setup the AnV Error Low = 0.00 , High = 5.00, and Error Value = 5.00 V

Thank you very much

I assume when you are looking for it to go active you are traveling at more then 10kph rather than testing while the car is stationary?

Seems to work on the bench. I did need to hold the voltage at 0 for a couple of seconds before it activated.

Next step is a full PC log while you activate the switches.

Looking at the log it actually looks like when you are requesting cruise control on, the voltage on the input is going to 4.98V

This would suggest that your ON Switch voltage should be 4.98

It seem to be at 0 for more of the time. Making me think this is the state that the switch is in normally rather than when you are pressing the button.

 

Also just noticed you are on 5.5.6 firmware I was testing on 5.6.4 can you upgrade to 5.6.4 firmware and see if you still have an issue.

Has there been a change to how long you need to hold down the ON button for? 

In my car it's seemed harder to get it started for some reason, pretty sure nothing physical has changed.

Will take some logs when my car's back together.

Hi Davidv

The reason that why I hold on the ON button because last message from Simon that he told me for hold for a few second. So I tried to hold it.

Today I will update firmware and try it again.

Thank you

I have just tested this here, the following image shows my results:

Can you record a PCLog on your updated firmware showing each of the buttons being pressed?

Dear All,

I got it already. I updated firm on my laptop but forgot to update on ECU. It's difficult to tune for smooth running, I'll try it.

Thank you very much you guys for helping me

Best Regards,
