Does anybody know what is the pin out of MR563487/MU801584?
As far as I know
1 - throttle position sensor middle
2 - ?reference voltage +5V?
3 - ?Idle position signal?
4 - break switch down
5 - break switch up
6 - power source - ignition switch
7 - cruise control vacuum pump release valve
8 - cruise control vacuum pump control valve
9 - cruise control switch CAN/SET/RES
10 - vehicle speed sensor
11 - ?service data link on OBDII 13 pin?
12 - cruise control switch ON/OFF
13 - clutch switch
14 - ground
15 - combination meter
16 - cruise control vacuum pump motor

 

Just do not write all together, I cant read that fast

 

I no kidding just replaced that ecu but have no idea what that pin is. A buddy of mine (ASE Cert Mechanic) was troubleshooting cause my cc wasn't working. I let him borrow my repair manual cd because it has a wiring diagram for that system (and all the other systems too). He said the vacuum pump wasn't getting power. So he shot the wires back to that ecu and said power wasn't getting from that ecu to the vacuum pump and the ecu would need to be replaced. I actually found one on eBay for $35. Anyway, replaced the ecu but have to get my car back to my buddy so he can reset the system. He says after the reset it should be good to go...we'll see. Sorry I can't be more help but as soon as I get my repair manual CD back I'll let you know.

 

I already have service manual but I cannot figure out pin 2. It goes from engine ecu 87 pin to pin 2 on auto cruise control ecu. but no idea what this wire is.

 

Actually you can reset the system by yourself, put ignition switch to Ready state, but do not ignite and disconnect battery, wait for 5 minutes, and connect it again, mind the polarity(disconnect negative).

 

^^^Thanks bro.^^^
I'll try that tonight when I get home from work.

 

Ok, it seems nobody has the info about the pinout, right?

 

C'mon, don't tell me that there is nobody out there with the knowledge....
