Collision Avoidance and Parking Assist Systems: Testing and Inspection
BACK WARNING CONTROL MODULEALARM RANGE
Upon detecting an object at each range out of 3 ranges as stated below within the operation range, it will generate alarm.
First alarm: Object comes near to the sensor located at the rear of vehicle, within 81 - 120 cm
Second alarm: Object comes near to the sensor located at the rear of vehicle, within 41 - 80 cm
Third alarm: Object comes near to the sensor located at the rear of vehicle, within 40 cm
NOTE:
1. Time tolerance of the above waveform: Time ±10%
2. At nearer distance than 25 cm, detection may not occur
3. Alarm will be generated with vehicle reversing speed 5 km/h or less.
For moving target, maximum operation speed shall be target approach speed of 5 km/h.
4. When the vehicle or the target is moving, sequential alarm generation or effective alarm may be failed.
5. Misalarm may occur in the following conditions.
- Irregular road surface, gravel road, reversing toward grass.
- Horn, motorcycle engine noise, large vehicle air brake, or other object generating ultrasonic wave is near.
- When a wireless transmitter is used near to the sensor.
- Dirt on the sensor
6. Sequential alarm may not occur due to the reversing speed or the target shape.
DIAGNOSIS AND INDICATION
1. Operate with ignition switch on and shift the lever to position "R".
2. Then it checks the system condition.
If no trouble, it generates buzzer alarm sound for 0.065 seconds. In case of system failure, buzzer alarm is generated 3 times continuously with the interval of 0.05 seconds or it does not generate.
3. Effective operation range is 5 km/h or less for the vehicle speed.
1. Diagnosis
Ignition switch on and shift the lever to position "R" MICOM checks the sensor condition, and generates buzzer sound for 0.3 seconds if it is O.K.
2. Diagnosis mode
In case of system failure, turns on the repair switch that is installed at the back warning unit then it indicates the failed point as follows.
a. Side left sensor failure beep-beep
b. Rear left sensor failure beep beep-beep beep-beep beep
c. Rear right sensor failure beep beep beep beep beep beep-beep beep beep
d. Side right sensor failure beep beep beep beep-beep beep beep beep
NOTE: Upon failure of two or more sensors, it generates alarm in the order of SL-RL-RR-SR sensor.
