Does A/T clutch pressure control solenoid valve B work properly?

YES -Replace the main valve body (shift valve B) or the transmission, then go to step 13.

NO -Replace A/T clutch pressure control solenoid valve B (see A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE A AND B REPLACEMENT ), then go to step 13.
Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
