P1816 PNP SWITCH

Description

INFOID:0000000001500040

The A/T PNP switch transmits the A/T position indicator signal (PNP switch signal) via CAN communication to
the transfer control unit.  DTC P1816 will set when the A/T PNP switch signal is malfunctioning or there is a
communication error.

P1817 ACTUATOR MOTOR

P1817 ACTUATOR MOTOR

Description

INFOID:0000000001500045

The actuator motor receives signals from the transfer control unit and controls shift rods which shift the trans-
fer case.  DTC P1817 will set when any of the following occur:
• Motor does not operate properly due to open or short circuit in actuator motor.
• Malfunction is detected in the actuator motor. (When 4WD shift switch is operated and actuator motor does

not operate)

• Malfunction is detected in transfer shift high relay or transfer shift low relay.
