dani_r Posted October 16, 2011 Share Posted October 16, 2011 Hello all! My friend has just picked up a 1993 Toyota Majesta Crown with a 2JZ-GE ( not the 1UZ v8 ) There are a few electrical issues that we can't seem to figure out. Dash display doesn't read the speed, fuel or engine temp. It also doesnt change when you press the ride height and TEMS buttons. They just stay lit up. A speed signal seems to be reaching the dash as the HUD that shows on the windscreen is changing, however the LCD screen is goosed and not showing the numbers correctly. We re-installed the air ride suspension as it was about 1" off the floor on some dodgy cut springs and it was horrible. We can't seem to get it to adjust. Any ideas would be much appreciated.

Guest Unders Posted October 24, 2011 Share Posted October 24, 2011 Well the suspension does adjust now. And the TEMS button seems to work. However when you press the height adjust or TEMS button it still doesn't change the lights on the dashboard. Speed fuel and temp gauge still not working. Any ideas or pointers would be appreciated.

Swampy442 Posted October 25, 2011 Share Posted October 25, 2011 Dash lights could be bulbs, for the gauges have you checked all the fuses? Quote Link to comment Share on other sites More sharing options...
Guest Unders Posted October 25, 2011 Share Posted October 25, 2011 Checked all the fuses I can find. Its definitively not bulb issue. Its digital clocks that read 188km/h I will get a pic up to show you. Easier than describing. Quote Link to comment Share on other sites More sharing options...
Guest Unders Posted October 26, 2011 Share Posted October 26, 2011 [ATTACH=CONFIG]140924[/ATTACH] The displays across the bottom work perfectly. The only thing that works on the top part is the light that signifies O/D for the autobox. And whatever I press the lights for the suspension never change but they function ok. The main thing I want to get working is the speedo. This is all it shows whatever speed I'm at Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 26, 2011 Share Posted October 26, 2011 Looks quite similar to a Soarer dash. If its showing 188 all the time Id say the dash is busted. You could try taking it out and cleaning/reseating the plugs, they clip into the dash but the contacts are on a flexible PCB. Also check for any poor quality speedo convertors.

Guest Unders Posted October 26, 2011 Share Posted October 26, 2011 I really hope its not busted. Don't think it will be easy finding another one. I have tried resetting the plugs and have not spotted any converters back there. Could it have anything to do with the Cobra alarm? It looks to be wired into pretty much everything further down under the dash. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 27, 2011 Share Posted October 27, 2011 One way to find out isnt there Dont think alarms ahave anything to do with the speedo though, just the igniton I would have thought. Quote Link to comment Share on other sites More sharing options...
