U0101: Lost Communication with TCM on ISF
Do you happen to know where i can locate the fuse for the TCM or a wiring diagram TCM-ECU? The only fuse box as per the fuse diagram that I can see relates to the transmission is the one below (15) which is located on the right side drivers side (AUS) panel. It's 7.5amps and looks to be good and not broken. -

Some more info: Battery Voltage with engine off = ~12.7 Control module voltage = 13.828V Oxygen Sensor Output voltage (B2-S2)= 0.155V <------is this something to be worried about? Oxygen Sensor Output voltage (B1-S2)= 0.855V Oxygen Sensor voltage (B1-S1)= 3.246V Oxygen Sensor voltage (B2-S1)= 3.241V Oxygen Sensor Current (B1-S1)= -0.02mA Oxygen Sensor Current (B2-S1)= -0.03mA It fault codes seems to only appear for : ECU (#e8) = U0101 Lost Communication with TCM 1/2 & 2/2 No faults for ECU 2 (#e9)
