P1813 4WD SHIFT SWITCH

P1813 4WD SHIFT SWITCH

Description

INFOID:0000000003937340

The 4WD shift switch allows the driver to select 2WD or 4WD and 4H or 4LO.  DTC P1813 will set if more than
two switch inputs are simultaneously detected by the transfer control unit due to a short circuit in the 4WD shift
switch.
