Multiple Component Checks
4WD Shift Switch
Check continuity between each terminal.
2-4WD Shift Solenoid Valve and Transfer Fluid Temperature Sensor
Measure resistance between terminals of transfer terminal cord assembly sub-harness connector located on rear-right of transfer unit.
4WD Solenoid Valve, Clutch Pressure Switch and Line Pressure Switch
Measure resistance between terminals of transfer terminal cord assembly sub-harness connector located on rear-right of transfer unit.
Front Revolution Sensor
Measure resistance between terminals of front revolution sensor sub-harness connector located on rear-right of transfer unit.
Transfer Dropping Resistor
Check resistance between terminals.
Resistance: 11.2 - 12.8 ohms
ATP Switch, Neutral-4LO Switch and Wait Detection Switch
Measure resistance between terminals of transfer switch assembly sub-harness connector located on rear-right of transfer unit.
NOTE: When shifting from "4LO" to "4H", continuity exists while "Wait" function is operating. (No continuity exists when "Wait" function is canceled.)
Transfer Motor
Apply battery voltage directly to transfer motor assembly sub-harness connector located on rear-right of transfer unit. (Positive: Terminal 14, Negative: Terminal 15) Transfer motor should operate.
Transfer Motor Relay
1. Apply battery voltage directly to terminals 3 and 4.
2. Check continuity between terminals 1 and 2.
Transfer Sub-harness
FRONT REVOLUTION SENSOR SUB-HARNESS CONNECTOR
Check continuity between terminals shown in the figure.
TRANSFER SWITCH ASSEMBLY SUB-HARNESS CONNECTOR
Check continuity between terminals shown in the figure.
TRANSFER TERMINAL CORD ASSEMBLY SUB-HARNESS CONNECTOR
Check continuity between terminals shown in the figure.
Terminals on solenoid valve
Transfer Shift Relay (High & low)
Check continuity between terminals 3 and 4.
