Drawing/Pinout for Aisin Tranny ECU 850

posted by  someone claiming to be BobD on  Tue Apr 8 10:08 CST 2003 [RELATED]

Hi,
I am trying to eliminate the CE message from the transmission ECU for the flashing arrow/CE due to a "damp" PNP switch. Can anyone provide a drawing or a pinout of the Aisin ECU used for the transmission control unit? Better yet, can anyone provide the address in the internal eeprom where the code is stored for the PNP switch? I have my Aisin unit apart and I see a 24C02 serial EEPROM. My thinking is to find the location where the fault is stored and erase the fault code myself (I do have the capability to program these chips). Otherwise I need a Volvo scan tool to reset this code.
I have a 1996 850 (non-turbo). (Blue).

Thanks.
