1. DISCONNECT WIRING CONNECTOR
2. MEASURE RESISTANCEMeasure the resistance between SOL and SOL .
Resistance:
6.0±11.0
3. CHECK SOLENOID OPERATION
(a) Connect the battery positive terminal to the solenoid terminal
SOL .
(b) C onnect the battery negative terminal to the solenoid
terminal SOL .
(c) Check that the solenoid is clicked. If faulty, replace the pressure control valve with the solenoid
valve.
NOTICE:
w Do not apply voltage for more than 30 seconds to avoid
burning out the solenoid.
w If repeating this step, wait until the solenoid cools down
enough that it can be touched by hand.
