Hi,

 

After such a good response to my main beam issue (which sorted the problem, cheers again!), I wonder if you guys can help me out with the cruise control.

 

On my 1993 TT Auto - Import, the cruise control does not work. The green light comes on to say its activated, but I cannot set cruise.

I have read bits and bobs from different websites, but you lot on here know your stuff!

 

I've read about switches on the brake pedal going, connections in the steering wheel, one site even said there was an error code that you can make flash on the cruise control light?

 

Has anyone fixed this on a TT Auto - Import before? Is there a logical approach to it?

 

My car now displays in MPH and is delimited, Once (IF) I get the cruise working, will I be able to cruise up around the 70 mph mark, or will it still have a restriction?

 

Thankyou in advance!

Look forward to reading your replies,

 

Cheers

 

Chris.

the cruise only works at a certain speed anyway, have you checked all fuses and relays?

Think it only works above 47mph mate

Think it only works above 47mph mate

 

 

Mine kicks in at 50 km/h and doesnt go above 115km/h

 

Not sure if that has anything to do with it not being de-restricted!

First check is to switch on the CC, get to about 50mph, put your foot under the brake pedal and pull it towards you, then try and engage the cruise... Let us know how you get on with that :)

Cheers guys,

 

Will try that Andy. I guess thats In case the brake is sitting too low, and making the contact on the switch.

 

Will let you know how I get on,

 

cheers again,

 

Chris.

Hi again,

 

No luck with pulling the brake up. There is hardly any play on the brake that way at all. I suppose the next one is the switch on the brake?

 

Cheers for the help guys, is always easier to talk to someone thats been trough it before, rather than tackle it from sratch.

Hi All,

 

I spent a good 5 hours on the car yesterday, to try and sort this cruise control prob out.

 

I ran all of the diagnostic checks from the manual (http://www.300zx-twinturbo.com/cgi-bin/manual.cgi) for the ASCD system.

 

The fault now being that I have no 12v supply to my ASCD control box harness.

 

I printed off the schematic of the ASCD system (under the electrical section of the manual, page 99)

 

I went through the scematic and checked each section bit by bit.

 

My cruise control light comes on

 

My brake lights work, so the stop lamp switch is working? Or are there 2 switches? - But this shouldnt stop the 12v supply to the ASCD box?

 

Horn fuse ok

 

ASCD hold relay clicks when the cruise is turned on and off

 

ASCD cancel relay in place

 

I'm stumped! Gonna have to have a round 2 soon, and will delve deeper. Before I get my head stuck in the footwell again...has anyone else got this far before and have managed to fix their cruise control??

 

Any help would be very much appreciated.

 

Cheers,

 

Chris.

is the connector on the ascd actuator (the one that actually controls the 2nd throttle cable) plugged in ?
