NO >> Repair or replace damaged parts.
Component Inspection (Shift Lock Solenoid)
1.CHECK SHIFT LOCK SOLENOID
Apply voltage to terminals of shift lock solenoid and park position switch (shift selector) connector and check that shift lock solenoid is activated.
CAUTION:
- Connect a fuse between the terminals when applying voltage.
- Never cause shorting between terminals.
Is the inspection
result normal?
YES >> Inspection End.
NO >> Replace CVT shift selector. Refer to TM-253, "Removal and Installation".
Component Inspection (Park Position Switch)
1.CHECK PARK POSITION SWITCH (SHIFT SELECTOR)

CAUTION:
- Connect a fuse between the terminals when applying voltage.
- Never cause shorting between terminals.
Is the inspection
result normal?
YES >> Inspection End.
NO >> Replace CVT shift selector. Refer to TM-253, "Removal and Installation".
Component Inspection (Stop Lamp Switch)
1.CHECK STOP LAMP SWITCH
Check the continuity between the stop lamp switch connector terminals.
Is the inspection
result normal?
YES >> Inspection End.
NO >> Replace stop lamp switch. Refer to BR-22, "Exploded View".
