P1813 4WD SHIFT SWITCH

P1813 4WD SHIFT SWITCH

Description

INFOID:0000000005258385

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.

Diagnosis Procedure

INFOID:0000000005258387

Regarding Wiring Diagram information, refer to 

DLN-240, "Wiring Diagram - PART TIME 4WD SYSTEM -"

.

1.

CHECK 4WD SHIFT SWITCH SIGNAL

With CONSULT-III

1. Turn ignition switch “ON”.

2. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-III.

3. Read out ON/OFF switching action of the “2WD SWITCH”, “4H SWITCH”, “4L SWITCH” with operating

4WD shift switch.

Without CONSULT-III

1. Turn ignition switch “ON”.

2. Check voltage between transfer control unit harness connector

terminals and ground.

Are the inspection results normal?

YES 

>> GO TO 5.
