Precaution for DCA System Service
CAUTION:
- Turn the DCA system OFF in conditions similar to driving, such as free rollers or a chassis dynamometer.
- Erase DTC when replacing parts of DCA system, then check the operation of DCA system after radar alignment if necessary.
PRECAUTION FOR ICC SENSOR
- Never use the ICC sensor removed from vehicle. Never disassemble or remodel.
- Never install a part that the radar irradiation range
is interfered with.
- If a part interferes with the radar irradiation range, then the following conditions are caused:
- The condition of ICC sensor becomes equal to an unclean condition, and this makes it difficult to measure the distance between cars.
- When it is impossible to measure the distance between cars, the following functions stop and DTC is detected.
- Forward Emergency Braking (FEB)
- Intelligent Cruise Control (ICC)
- Distance Control Assist (DCA)
- Predictive Forward Collision Warning (PFCW)
