Inspection Procedure

WARNING: This page is about a different car, the 2005 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: When replacing the master cylinder solenoid, perform zero point CALIBRATION  .

HINT:

Start the inspection from step 1 when using the hand-held tester and start from step 3 when not using the hand-held tester.

  1. READ VALUE OF HAND-HELD TESTER (MOMENTARY INTERRUPTION OF REAR SPEED SENSOR) (SEE  CHECK FOR INTERMITTENT PROBLEMS   )
