  3. Verify that the selector lever cannot be shifted from the P position without depressing the brake pedal.
  4. Depress the brake pedal and verify that the selector lever cannot be shifted from the P position. If there is any malfunction, inspect the interlock cable. (See «INTERLOCK CABLE INSPECTION»(ref-345341-S23088094642009102000000) ).

KEY INTERLOCK INSPECTION

  1. Verify that the ignition key cannot be pulled out except in the P position. If there is any malfunction, inspect the interlock cable. (See «INTERLOCK CABLE INSPECTION»(ref-345341-S23088094642009102000000) ).
