Control Circuit Inspection

■ Check shorted to battery in harness 

1. Ignition "OFF"
2. Disconnect Hub Solenoid Valve and TCCM main harness connector.
3. Ignition "ON"
4. Measure voltage between Control terminal of Hub Solenoid Valve harness connector and chassis ground.

Specification : 0V 

5. Is the measured voltage within specification?

   YES 

   • Go to Next procedure.

   NO 

   • Check for short to battery in harness.
   • Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check for open in harness 

1. Ignition "OFF"
2. Disconnect Hub Solenoid Valve and TCCM main harness connector.
3. Measure resistance between Control terminal of Hub Solenoid Valve harness connector and Control terminal of TCCM harness connector.

Specification : 1Ω below 

4. Is the measured resistance within specification?

   YES 

   • Check for shorted to battery in harness.

   NO 

   • Check for open in harness.
   • Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
