Note

C134551

Linear Solenoid Valve Offset Learning Not Programmed

The linear solenoid valve offset learning value is not stored.

  • Perform linear solenoid valve offset learning and check for DTCs. If no DTCs are output again, the valve is normal.
  • No. 1 skid control ECU (brake booster with master cylinder assembly)

Does not come on

Output ECU: No. 1 skid control ECU (brake booster with master cylinder assembly)

HINT:

During Dealer Mode, related DTCs are cleared.

C134554

Linear Solenoid Valve Offset Learning Missing Calibration

The linear solenoid valve offset learning value cannot be obtained.

  • Perform linear solenoid valve offset learning and check for DTCs. If no DTCs are output again, the valve is normal.
  • No. 1 skid control ECU (brake booster with master cylinder assembly)

Does not come on

Output ECU: No. 1 skid control ECU (brake booster with master cylinder assembly)

CAUTION / NOTICE / HINT

NOTICE:

After replacing the No. 1 skid control ECU (brake booster with master cylinder assembly), perform "Calibration" after performing "Reset Memory".

Tester Display

Calibration

  1. The auxiliary battery voltage is 11 to 15.5 V when the ignition switch is turned ON (READY).
  2. The brake booster with master cylinder assembly is not hot.
  3. The hybrid control system is not malfunctioning.
  4. The shift state indicator shows that the shift lever is in P.
  5. The READY light in the combination meter assembly is illuminated.
  6. The brake pedal is not depressed.
  7. The parking brake is released.
  8. DTCs C145100 or C145151 is not output. (If it is output, bleed the air from the high-pressure tube.)
