P1816 PNP SWITCH

P1816 PNP SWITCH

Description

INFOID:0000000007357517

The transmission range switch transmits the A/T position indicator signal (transmission range switch signal)

via CAN communication to the transfer control unit. DTC P1816 will set when the transmission range switch

signal is malfunctioning or there is a communication error.

P1817 ACTUATOR MOTOR

Description

INFOID:0000000007357520

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.
