Hi. The auto-elec that I was going to see is not able to look into this for me right now, so I've engaged another that actually installs aftermarket cruise control and knows his way around existing systems. The plugs for where the clutch pedal was installed have been taped over with duct tape. I could not find the clutch pedal switch installed, however, there is a wire wrapped in conduit hanging down over that area. It has been snipped and just left hanging there. Black, green wire and another white and green wire, both wrapped in corrugated black conduit. There is a single wire running from the brake pedal, twisted together without solder, running over to the auto gearbox selector. I assume that the cut wires are redundant if the ECM has been switched to an auto one. Or, am I getting mixed up with the ECU? I have no idea. haha. I found a post from a member of the Whirlpool forum who got cruise working: https://whrl.pl/Reng1q. He has a manual Corolla, and he had to run two wires from the spiral assembly to the ECM in the engine bay for cruise to work. I wonder if I should do the same being that I'm working with a manual harness? I'm just not too sure what to do with the clutch switch wires if they were indeed those wires. Pressing on the brake cancels cruise on an auto, so do I need to bridge that wire that was added, running to the gearbox selector? It controls the unlocking of the gearbox selector when the brake is pressed down. Any help at all from anyone is much appreciated as I will pass it onto the tech.

Hi Tony, thanks for the reply. Regarding the WOVS, we were not provided a WOVS report at the time of sale. I believe it was not legislated that used car dealers had to provide this report at the time of sale until around late 2010/11. I can confirm that it was a front end collision. Our local dealer found the front passenger airbag to be aftermarket on an inspection for the Takata recalls a few years back. They found the aftermarket airbag welded to the original Toyota airbag housing with two spot welds. The original wiring harness was also salvaged and joined to the aftermarket airbag by twisting the wires together and wrapping electrical tape around them. My friend is a mechanic and replaced it with a brand new genuine one to correct an intermittent airbag warning light. He also changed the inhibitor switch for me. My Toyota dealer did the diagnostic work but did not replace the parts. Fuses and relays were checked and found to be in order. The only fault found was the inhibitor switch as open circuit. Thanks for the article, I will pass this on to my auto elec. as it may assist him in troubleshooting. I do agree that the manual > auto conversion was not done with cruise control in mind. Thanks for your help, and I will be sure to update the thread with the final outcome. Thanks Ian. I can confirm that the car was indeed a manual before it was declared a repairable write-off. I'm seeing an auto electrician tomorrow to have some safety lights added to the car. Do you think it is worth having him tackle this job? If he needs to remove the clutch switch, what is involved with the "bridging" process? I want to try to point him on the right track if I can. Your help is greatly appreciated.

Hello, I have a ZRE152R Corolla sedan automatic that was purchased from a dealer on Parramatta Rd. no longer in business (of course). The dealer sold us a repairable write-off just before legislation changed, preventing the sale and registration of these cars. Cruise control has never worked on the car. The Cruise light turns on, but pushing the stalk down to set the speed does nothing. I took it to a Toyota dealer, and they diagnosed the Inhibitor switch as open circuit, it has since been replaced but it has not solved the issue. The car is an ex-manual that was somehow converted to an automatic, and I have a sneaking suspicion that this is the cause of my trouble with cruise control. I refuse to sell this car privately or trade it in at any dealer with a repairable WOVS status. I just want to make this car my own until its end of life. Based on the fact that this car is an ex-manual, what might be missing from the car to get cruise control working? There are no error codes on the car. Any help at all is much appreciated. Thank you.

Hi. I have had some work done to my car involving the dashboard. I want to confirm if the inside electric mirror control button is illuminated. I can’t seem to recall if it ever was illuminated so I’m hoping an owner of a ZRE152R (Corolla 07 - 10 Sedan) can confirm. Cheers
