Wow...thanks for all of the tips! I'll take them step by step tomorrow until I find the problem. If I nail it, I'll post the result.

Yes, there's a Code 51 stored in the Super Monitor diagnostics. Code 51 in the TSRM paints a very broad brush as to what it could be though. Was hoping there was a common cause of no idle-up when a/c is turned on.

Okay, I've combed the forums and the TSRM. Which of you Supra techies can tell me what's wrong...when I turn on the a/c, the idle doesn't go up. It drops to around 500, and sometimes almost stalls. Sensor? Wire? Relay? Where do I look? Thanks! 86.5 MKIII, 7M-GE, 5-Speed

Oh jeez....I think maybe the wiring just wore me out too much to think of that. :) I guess the days in a month might be important to someone using the calendar, duh. Thanks Girl! Hey, when I ran the diag mode for the first time, the C/C (cruise control?) displays a "-". Is that okay? Also, at...

Hey Suprra Girl. I undertook the job of the year and hardwired a harness into an 86.5 n/a for a Supermonitor...a lot of work but worth it because it works! :) Anyhow, I don't understand your "list of years". If I put "03", it still displays the year as "03", not "08", so am I missing something?

I have an 86.5 MKIII. It had the engine fan and single a/c fan. I live near Death Valley and wanted superior cooling to avoid head work. I found a donor car and changed out the single a/c fan to the double unit. I still let them run off of the a/c relay. I got a hold of that fan #3 and tried...

I have an 86.5 MKIII. The car is bone stock and loaded to the gills. Everything works great EXCEPT the "Low" fan blower setting on the climate controls. When the system is in "Auto" mode and I raise and lower the temp setting, Low is used by the system and works, but when I select Low manually...

Thanks Suze! The pinout diagram is great, although the last 10 times I viewed that page, it ended at the cruise control plug. Thanks for fixing. If anyone has an SM harness plug you're willing to sell, please let me know. I'd love to see this thing actually work! :1zhelp:

Hello All! I'm not new to automotive mechanical or electrical, but I am new to SupraDom. I picked up an 86.5 in nearly pristine condition with only 115k. I've read through forums and blogs for 2 weeks about the Super Monitor, which seems like a subject that's been done to death without much...
