INSPECTION PROCEDURE

NOTICE:
When replacing the master cylinder solenoid, perform calibration Programming and Relearning.

PROCEDURE

1. RECONFIRM DTC

HINT
These codes are stored when a problem is detected in the master cylinder solenoid.

The solenoid circuit is in the master cylinder solenoid.

Therefore, solenoid circuit inspections and solenoid unit inspections cannot be performed. Be sure to check if any DTC is output before replacing the master cylinder solenoid.

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Drive the vehicle at a speed of approximately 32 km/h (20 mph) or more for 60 seconds or more.

(c) Check if the same DTCs are output Reading and Clearing Diagnostic Trouble Codes.

Result





B -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting

A -- REPLACE MASTER CYLINDER SOLENOID Disassembly
