I got it working!! Turned out there were two things wrong, 1. I had a bad cruise actuator unit, it had jammed gears that had stripped out, hence why it was clicking off the relay when testing it. 2. I had a bad tap connector onto the VSS (Vehicle Speed Sensor) wire, so it wasn't sensing the speed. I tested it with all four wheels in the air to finally get it figured out, so far it works great and is a joy to use on the highway.

Thanks. Let me know if you find anything. I'm going to keep rechecking the wiring to the engine bay and swap out the cruise actuator for another unit I have here.

The module came back to life after that event 24 hours later (maybe bad caps or something?) but it works the same and I now have a second cruise module that has the same results. No, I didn't ground any other pins when I initially did the test. I have double checked and tried the test again with the same results except the system comes back to life again instantly after turning the key off and on. When grounding the pins, the relay just clicks and the system shuts off. I'm going to test all wires to the cruise module and try and get a proper reading on the resistances across the different motors.

I have 12v hitting pin 4 when the switch is on. I tried testing the actuator function by grounding those pins, however it didn't work out so great. The relay clicked off on the module, and now the thing clicks on but the main switch light doesn't work. I think something might have been damaged by that test.

This one either has an internal vacuum pump, or is purely servo driven. It does not have any external vacuum lines, or an external vacuum test port from what I can tell. It is part number R174737 https://www.google.ca/search?q=R174737&es_sm=91&source=lnms&tbm=isch&sa=X&ved=0CAgQ_AUoAmoVChMIz7SVrYepxwIV04uSCh3elwYN&biw=1920&bih=1036#imgrc=1NYf4zr8-n8KtM%3A

I don't have the clutch switch yet, the wires are connected down there though. The circuit is continuous from pin 11 to pin 16 (brake and clutch switches) when the brake isn't applied.

I get 12v going right to pins 9 and 10 on the circuit board of the cruise module when the cruise sub switch buttons are pressed, no issue with how its wired to my knowledge. I've also tried connecting pin 4 WB to 12v, and the cruise still doesn't engage. I may try wiring a bulb to each of the motor outputs of the cruise module to know if it is commanding them to operate or not. That way I could rule out either the actuator or cruise module.
-
Also there is a black wire that terminates at pin 5 of B68 that isn't connected to anything. This may be something to do with the set resume cancel switch? Should it connect to something?
-
Yes I do, I get a pulsating 4.7 volts on there, so that one is correct. The Black / Orange wire is not connected, also the White / Black (AT) on pin 4 is not connected. I'm driving at over 40km/h when attempting to set cruise and nothing is happening.
-
Well, I might be wrong about the B54 connector thing as the (AT) is on the cruise module side of the wire, so it should not be connected to anything. I'm stuck on whatever is inhibiting it setting. Is there any way to troubleshoot this further?
-
I have verified the power lines and ground. Though I have now got the cruise light to come on (the issue was the wire colors on the cruise control sub switch harness were not the same as the diagram). My issue now is that the system turns on, but you can't set a speed - i.e. it doesn't cruise. I've tested the sub switch wires, and they are good. However the one missing link is the B54 connector pin a11 - my car is MT, however the diagram indicates that it should be still connected to something (the neutral switch maybe?). I have no B54 connector that I can find under the dash, so I left the wire unconnected. Maybe this is inhibiting it?

I am swapping cruise control into an '01 Legacy L / Brighton, and I need some help troubleshooting the completed install. What I've done so far: - Install cruise main switch, steering wheel controls, actuator and cruise computer - Wire cruise actuator through firewall to cruise computer - Wire cruise computer to all respective wires in the vehicle according to the wiring diagram (this was quite a procedure) - Wired in new 4-wire brake and clutch pedal switches and confirmed it has continuity when no pedals are pressed - Tested and verified all switches, bulbs, ignition power sources, etc - Then I plugged in the cruise module and tried it out, and the light on the cruise control main switch will not come on when I press it (I'm assuming it means 'enable the cruise system'). - I have checked fuse 18 and 15, and backprobed all points from the switch and the bulbs to check that the module genuinely isn't responding, but is otherwise powered. My issue is as follows: The cruise enable switch on the dash does not light up when pressed. Bulb works, switch works, power goes to the cruise module, what else do I check?? UPDATE The cruise module wasn't enabling because the sub-switch output to pin 10 of the cruise module was wired at connector B68 by wire-color and not by pin number. On my particular vehicle (Legacy Brighton L), the wire colors on the steering-wheel side of that harness are incorrect and/or mislabeled in either the vehicle or the wiring diagram. Doing this by pin number means that the cruise module now powers on, and the correct 12v signal is seen at the module when the set, resume and cancel buttons are operated, respectively. The issue now is that it will not set cruise, when driving over 40km/h - the switches do not do anything. I need to troubleshoot whether something is inhibiting the cruise system from setting, or whether it is trying to set the cruise, but the actuator is not working. Any ideas are welcome. Please let me know what you guys think is the best next-step to take to get this working. Some photos of the progress Image 1 Image 2 Image 3 Image 4 Image 5
