I LS swapped my Land Rover Discovery 2 and one of the remaining items is getting the 4Low to work. I have developed a CANbus gateway so I am able to send/receive CAN messages. It?s an E38 ECM from a 2010 Silverado.
Does anyone know the PID and messages to enable / disable 4 Low?
I?ve tried the extended PID 0x2D1 with the first message (byte A) set to either 0x00 (off?) or 0x01 (on?) but that doesn?t seem to work. Anyone know the right PID/messages?
Extra credit if you also know the PID/messages for the Tap Up and Tap Down signals.
Thanks in advance!
