WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- After replacing the master cylinder solenoid, perform zero point calibration ().
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.
Clear the DTCs ().
Drive the vehicle at a speed of approximately 32 km/h (20 mph) or more for 60 seconds or more.
Check if the same DTCs are output ().
Result | Proceed to |
DTC is not output | A |
DTC is output (for LHD) | B |
