19. Press the interlock cable lock piece in until it is locked. CAUTION: Applying a load to the interlock cable while pressing the lock piece in can affect the lock unit operation.
20. Remove the a 1.5mm {0.059 in} round bar or similar from the lock unit holes A, B, and C.
21. Connect the brake switch connector with the brake pedal released. CAUTION: The clearance between the brake switch and the brake pedal is automatically adjusted to the correct amount when the brake switch connector is connected after the brake switch has been properly installed. If the brake switch is not properly installed or the connector is connected before installation, the clearance may be incorrect, causing a brake light malfunction. Therefore, always verify that the brake switch is properly installed before connecting the connector. Once the brake switch clearance has automatically been adjusted, it cannot be adjusted again. Therefore, replace the switch with a new one when replacing the power brake unit or the pedal, or performing any procedure that changes the pedal stroke.
22. Inspect shift lock operation. (See «SHIFT-LOCK INSPECTION»(ref-288765-S40978730082008062500000) ).
