Torque: 5 N*m (51 kgf*cm, 44 in.*lbf)
NOTICE: Do not install the dropped or shocked distance control ECU assembly.
2. INITIALIZE DISTANCE CONTROL ECU
NOTICE: After replacing the distance control ECU, it is necessary to initialize the distance control ECU so that the ECU can recognize the specification of the vehicle.
- Be sure to perform the following procedures after replacing the distance control ECU.
- Turn the ignition switch to the on position.
- Turn the cruise main switch on.
- With the brake pedal depressed, push the cruise control main switch to RES/ACC 3 times within 3 seconds. Check that the buzzer sounds at this time.
