DIAGNOSTIC PROCEDURE

1. 

CHECK 4WD SHIFT SWITCH SIGNAL

 With CONSULT-II

1.

Turn ignition switch “ON”. (Do not start engine.)

2.

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

3.

Read out ON/OFF switching action of the “2WD SWITCH”,
“AUTO SWITCH”, “LOCK SWITCH” and “4L SWITCH” while
operating 4WD shift switch.

 Without CONSULT-II

1.

Turn ignition switch “ON”. (Do not start engine.)

2.

Check voltage between transfer control unit harness connector
terminals and ground.
