Transfer Position Indicator Does Not Come ON at Ignition Switch ON but Engine Stops
Transfer Position Indicator Does Not Come ON at Ignition Switch ON but Engine Stops
Wiring Diagram
Circuit Description
Transfer position indicator operates according to the signal from 4WD control module. If the transfer control system is in good condition, transfer position indicator light up for 2 seconds when ignition switch is turned to ON position, and then turned to OFF position. If an abnormality is detected in the system, transfer position indicator remains lighting.
Troubleshooting
1. Transfer position indicator power supply check
Turn ignition switch to ON position.
Do other indicators come ON?
YES -
Go to Step 2.
NO -
Go to Step 3.
2. Check DTC
Connect scan tool to DLC with ignition switch OFF.
Turn ignition switch to ON position and check DTC.
Is there DTC(s) U0073, U0100, U0101, U0121 and/or U0155?
YES -
Go to applicable DTC diag. flow.
NO -
Substitute a known-good combination meter and recheck. If transfer position indicator still remains off, substitute a known-good 4WD control module and recheck.
3. CAN communication circuit check
Check CAN communication circuit between combination meter and 4WD control module referring to U0073 DTC U0073: Control Module Communication Bus Off:Motor-Shift Type (Transfer with Shift Actuator).
Is CAN communication circuit in good condition?
YES -
Go to Step 4.
NO -
Repair or replace.
4. "METER" fuse check
Turn ignition switch to OFF position.
Check for fuse blown to "METER" fuse in junction block assembly.
Is "METER" fuse in good condition?
YES -
Go to Step 5.
NO -
Replace "METER" fuse and check for short.
5. Combination meter power supply check
Remove combination meter referring to Service and Repair Combination Meter Removal and Installation.
Check proper connection to combination meter connector at "G28-1" and "G28-3" terminals.
If OK, then turn ignition switch to ON position and measure voltage between combination meter connector at "G28-1" terminal and vehicle body ground.
Is it 10 - 14 V?
YES -
Go to Step 6.
NO -
"PPL/RED" wire is open circuit.
6. Combination meter ground circuit check
Turn ignition switch to OFF position.
Measure resistance between combination meter connector at "G28-3" terminal and vehicle body ground.
Is resistance 1 ohms or less?
YES -
Substitute a known-good combination meter and recheck. If transfer position indicator still remains OFF, substitute a known-good 4WD control module and recheck.
NO -
"BLK" wire is open or high resistance circuit.
