2014年11月16日 · The ISC has 2 coils. They are referred to as coil pair A, and coil pair B. Coil Pair A-When looking into the ISC, coil pair A is pins 1, 2 and 3.-ISC Pin 2 is ground for coil pair A-ISC Pin 1 is a coil and goes to ECU pin 58-ISC Pin 3 is a coil and goes to ECU pin 59-IC107 is the ECU driver that will blow if coil pair A is bad. Coil Pair B

2011年4月1日 · The ISC did just fine, though as stated already - took a few more cranks and sometimes a second of throttle to get it idling normally. Btw, 3 out of 4 adjusters were easy as pie to adjust down.. the runt of the litter was a B*tch!

2013年8月31日 · IC105 controls ECU pins 67 and 68, Idle Speed Control (ISC) Servo (coil pair B). IC106 controls ECU pin 57, Fuel Pressure Solenoid (FPS), and ECU pin 105, Boost Control Solenoid (BCS). IC107 controls ECU pins 58 and 59, ISC Servo (coil pair A). IC108 controls ECU pin 53, EGR Solenoid, and ECU pin 62, Evap Purge Solenoid.

2008年5月11日 · I think it will lock itself at whatever Mitsu programmed it to when you ground those two (maybe its 30, I don't know). Once you ground them and set the idle to spec with the BISS your ISC reading after that will change with temperature, electrical load, AC load, PS load, and probably a bunch of other things. John

2016年5月20日 · So I sent my ECU to ECM Tuning to get some damage repaired and chipped last week and today I got a response about the damage repairs needed. Seems the ISC driver kursploded from a short, which explains why it was unplugged. The OEM replacement seems to be big money. Has anyone had any luck with...

2010年9月1日 · My idle started dropping under load and wouldn't maintain the 900rpm set in the eprom. Logger shows 120 trying to bring it up. I fiddled with the BISS to get the rpms up over 900 and the ISC counts went down to zero with no effect …

2009年2月8日 · I have been replacing the ISC (used) and one of the IC that used to control the ISC motor couple years ago, the idle worked properly at that time,but for some reason,now it is idling around 1500~2000rpm, the idling gets lower when the temp is reaching to normal range around 1100~1400rpm but sometimes it would get higher when it stops at the ...
