Howdy, I'm trying to sort out a 3 bars issue during start sequence. What began as a key fob issue, which led to a battery disconnect during troubleshooting, has become a transmission teaching sequence failure. I have checked all fuses and read through the other message threads. An Ancel FX3000 scanner returns the following fault: NO OR INCORRECT CAN MESSAGE FROM CONTROL UNIT N15/5 (ELECTRONIC SELECTOR LEVER MODULE CONTROL UNIT). The battery has a good charge, clutch is actuating with key switched on. Wheels are off the ground. Have done an inspection of wiring for obvious defects, grounds near batter posts, checked fuses, rear brake lights work, gone through shifting from P-R-N-D-M repeatedly, disconnectsd Pawl Switch Plug on tranny to verify clean connection, can hear actuator moving and some mechanical shifting going on in the trans, but never get a P indication on the display. I've run through the teaching steps with brake depressed for minutes at at time, rocked vehicle back and forth....Analogs (throttle, brake pressure, temp, yaw, steering wheel angle, etc) read good. Valves are cycling. It seems like the error message could be either a position mismatch or failed comms. Does anyone have experience testing for this specific fault, or know of test points where I can verify comms and voltage for the N15/5 module in the shifter, and would a module failure return just the subject fault message or multiple error codes. I've use the scanner to clear the fault, or at least try, but it's constant. I've not yet removed any mechanical components or solenoids, as the transmission teaching sequence fault only appeared following a battery disconnect to troubleshoot a broken key. It would also be great to know what specific components are used for teaching that are not used in normal operation, in case a component or wire was already failing prior to the transmission losing its position in memory. Thanks for the help in advance!
