DTC 96

CIRCUIT DIAGRAM











INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
Ignition voltage is supplied to the "4WD" indicator lamp through the "IG COIL" fuse. The 4WD switch is open when the transfer case is set in Two-Wheel-Drive (2WD) or "Neutral" range.
In 2WD mode, CKT " O/B" is supplied with current flowing through the "4WD" indicator lamp bulb filament.
The Electronic Brake Control Module (EBCM) senses this current through connector E124, terminal "6" and determines the vehicle is in 2WD mode.
In 4WD mode, CKT "O/B" is grounded by the 4WD switch. This causes to turn on the "4WD" indicator lamp and signals the EBCM determines the vehicle is in 4WD.

FAILURE CONDITION:
DTC 96 can be set anytime when the EBCM detects an open in CKT "C/B", open 4WD indicator lamp bulb filament, or open "IG COIL" fuse.
