Either im a dropkick or my cruise control doesnt work i push the little button on the right hand pod, click set coast, nothing. if i am just doing something wrong please tel me, the manual is in japanese and not particularly useful. otherwise, im going to delete the whoel thing and put a momo wheel in there, they look nice. is there much merit to selling the CC unit?
Your not a dropkick, you've done it rite. I don't think there'd be too much wrong. I love my CC. Couldn't cruise without it. Too many tickets!.
do you here a click from where the ecu is when you push the CC on button on the pod?? if not then it sounds like your CC computer is dead
DO either of the dash lights come on? One says "Cruise" and one says 'Cruise Cont". When you turn the cruise control on with the switch on the right side binnacle, the "Cruise" light should come on. When you hit 'set', the "Cruise Cont" light should come on. If the "Cruise" light doesn't come on when you press the cruise on switch, you've got a power or cruise control computer problem somewhere. If it comes on, but you can't set a cruise speed, it's likely that the switches fitted to the brake or clutch pedals are faulty or out of adjustment - the cruise control computer will think that the brake is being applied or clutch is pushed in, and it won't allow a speed to be set.
Thanks, yeah, the first light comes one, but no luck on the cruise cont light. itll have to be something in the brake or a dodgy switch in the steering wheel i guess. im getting a new wheel in as mine is falling apart, so i will mst likely be deleting it anyway. i honestly dont think i will ever use it.
Sorry, I may have got the description of which light lights up in the wrong order. The circuit diagram says teh "Crusie Cont" light comes on when teh crusie control is turned on, and the "Crusie" light comes on when the crusie speed is set. In any case, if you're at all handy with a multimeter, get to the ASCD control unit next to the ECU, and with the ignition on and the cruise control turned on, and the auto in drive if an auto, check the voltages on pins 5 and 11. Pin 11 should have zero volts on it, and when you press the brake pedal, you should see 12 volts. Pin 5 should have 12 volts on it, which should drop to zero volts when the clutch pedal is pressed in, or the auto selector is moved to neutral, or the cancel switch is pressed. The ASCD computer will not allow a speed to be set unless there is 12 volts on pin 5. If you don't have 12 volts on pin 5 with ign and ASCD on, but your cruise control light still comes on, then the fault will be an ASCD hold relay (the brown one in the passenger side footwell, from memory), or the neutral and parking position relay (auto shifter), brake or clutch switches. Sometimes the pedal switches move out of alignment and don't close properly, and sometimes if the brake pedal is slightly loose at the top of its travel, it can bounce around while driving, and cancel the cruise as well. It's also possible that your steering wheel is at fault. There are three slip ring connectors on the back of the wheel. If any aren't making contact, then your ASCD and/or horn won't work. Oh, and you can't set it below 48 KPH or thereabouts in any case.
Depends if you want to do it yourself or not. It takes a while, but it's not overly complicated. Since most autos already have cruise, I presume you've got a manual. If you've somehow got an auto without cruise, I imagine it would be very simple. The hardest part is modifying the manual clutch and brake pedal and adding the cancel switches - some pedal cutting and/or welding required. The rest is pretty straightforward. If you can pick up all the bits from this forum, I'd say anywhere from $200 to $300 is a fair price for the parts, depending on condition. If you have to pay someone to cut and weld, maybe add another $50 for their time. If you have to pay someone to put it in, then that could get expensive, as there's a few hours involved.
I think its time for me to invest in a multi meter pretty sure it should be included along with the spare tyre... regardless, its not too much use to me, so ill see whats wrong with and if anyone is interested they are welcome to make an offer.
Damn this cruise control!!, I have gone from "new wheel so delete cruise control" to "new wheel, so i need to find a new place to put my CC... sooo modify front bar and delete the foggies, move cruise control to the foggie button" im wondering if anyone else has done this, seems logical, little bit fiddly but not impossible. thoughts?
For some years my cruise control was like yours U/S. The problem with mine was the clutch switch needing adjustment. When I finally got it fixed I thought it was brilliant. When on the expressway I just set it to 100K and then can forget about the speed and just concentrate on what is on the road. You can also take your foot off the pedal to give it a stretch. It will maintain speed to within 1 or 2 kph even when going up or down a hill and it is apparently the most economical way to drive in terms of petrol consumption. I strongly recommend that you keep it. If you need a new wheel get a genuine one from a wrecker.
As mentioned, check your switches. Clutch if it's manual and your brake pedal. There's pads that these switches are triggered with and they could be worn. replace them or bodge something up. Have a read of this
The later Zeds with airbags had a stalk opposite the indicator stalk, as they couldn't put the cruise buttons on the steering wheel. That would probably be fairly easy to fit and make work. I also fitted the stock cruise buttons to a Momo steering wheel, and it looks good and works well.
Thanks guys, threw the new wheel on over the weekend, not a huge fan, guess that shows me the difference between "momo" and "momo initation" cant even see the speedo or tacho with it on, and the auto switch off thingy, that indicators dowhen you corner doesnt work. swapped back to my stocky, threw imitation momo in the back of the "parts i bought and now hate" cupboard. i have an auto btw, and im have checked all over the brake pedal and cant find any of these pads, can anyne post up a pick for me?
Sorry, don't have a picture, but the brake pedal has a bracket near the top (up near the pivot) with two green plastic pads. When the brake pedal is stationary, ie foot not on the brake, one pad actuates the brake light switch (holds it off), and the other actuates the ASCD cancel switch (holds it on). When the brake pedal is pushed, one switch turns the brake lights on, and the other cancels the cruise, if it is set. The ASCD cancel switch is the one with the blue connector. These switches are adjustable - they can be screwed in or out to adjust the depth. Maybe yours is out of adjustment, or the pad has worn or fallen out. If you can find an online version of the 300ZX manual or you have a copy, have a look at page "BR-6". It shows everything described above. You might need to remove the lower dash panel and the A/C duct in order to find the switches. Cheers,
