B12e0 Mercury Description

When the off-road switch is depressed, a signal is sent to the Transfer Case Control Module (TCCM) which alerts other modules along the HS-CAN that off-road mode is being requested. Other vehicle functions change to accommodate off-road mode and an indicator illuminates on the Off-Road Mode Switch confirming off-road mode. The OBDII code sets when in Off-Road Mode, the TCCM senses the indicator lamp circuit is not to factory specifications.
