If you look in RAVE at the ETM section for the Classic, B5 within the 'Circuit' section outlines tests you can do using a multimeter. It's a similar set up to the early V8 p38's.
classicjack said:This all sounds very familiar. I've been troubleshooting my cruise control for about a year with all the same results as you, I recently started driving with out steering wheel center piece which covers connector to spiral cassette ( also replaced recently from parts car ) and found these four wires when jiggled allow cruise to work. Loose wires at ecu and at this connector finally allow cruise to work, has been working now consistently for a week, for the first time in a year.
AH I was wondering this because there is a lamp in my instrument cluster that is next to the "TC" lamp that looks like an overhead view of the drive train showing the 4 wheels, axles, and drive shaft in the pattern of an "H" ...must be for something else then :think:adam1977 said:P.S: I believe the light on the cruise switch is the only indicator.
I suppose if I had a helper to turn the main cruise switch on and off i could feel around. But looking at the rave manual its a normally closed relay that opens when its in park or neutral. So I was wondering how likely this could be the problem since if its failed then it would just not open right?adam1977 said:It is on the passenger side if yours is a right hand drive example...which it isn't :think: so maybe it's behind the drivers side?
i can't remember how I figured out which relay was the lockout one, I might have followed the RAVE instructions and felt the correct relay when it 'clicked' :think:
So this is below the glove box it seems. I will investigate the correct relay and report back....though its raining right now so iI wont be able to for a little while.adam1977 said:I've just been refreshing my memory with the cruise control troubleshooting guide, the CC lockout relay is located on a metal carrier that hinges down once a nut is loosened and taken out on the passenger side of a right hand drive car. As I've never worked on a LHD Rangie I can only presume that yours is on the passenger side too (I'd have thought it would be too cramped to put all this where the steering column goes).
The metal carrier also holds the alarm ECU so can be easily identified; once you've located it then look for the 5 terminal relay that has the same white/slate wires as in the trouble shooting guide (page 15-terminals 86 & 30) follow the procedure as stated in the guide (test 4B) and if it passes the test move on to the next one (test 5B).
According to the guide, if it has failed then the causes are: WS wire, WY wire or the cruise control diode.
Let us know how you get on; all of this is making me want to re-investigate my own non functioning cruise control![]()
AHA! Well that makes sense...though I dont think it makes a difference because there is still no 12V to that switch at all :doh: I will however look at Test 1B as soon as it cools down outside.adam1977 said:You need to do Test B; Test A is for manual gearbox cars only. Start with Test 1B and work through the procedure![]()
