DIAGNOSIS

1. DIAGNOSIS

Turn the ignition switch ON, then shift the transaxle lever to 'R'. The Back Warning System is then checked.
If no trouble, it generates buzzer alarm sound for 0.3 seconds after 0.5 seconds from power approval. In case of
system failure, buzzer alarm is generated 3 times continuously with the interval of 0.3 seconds.

2. DIAGNOSIS MODE

Switch on diagnosis mode upon system failure.
In case of system failure, then it indicates the failed point as follows.

SENSOR CONNECTION CHECKING

Transmit ultrasonic wave to the sensors, boost input signal, and detect wave.
Waveform will be found, oscillating for a certain period of time.

1. Waveform for a normal sensor connection

2. Waveform for a failed sensor connection

Sensor connection will be checked for oscillating period of input signal 3V. If oscillating period is more than
0.8ms, it is normal.

A. Left sensor failure : beep-beep-beep
B. Right sensor failure : beep beep-beep beep-beep beep
C. Rear-right sensor failure : beep beep beep-beep beep beep-beep beep beep
D. Right side sensor failure : beep beep beep beep-beep beep beep beep-beep beep beep beep

WARNING

1. Range detected by back sensors is limited.

Watch back before reversing

2. There is a blind spot below the bumper. Low objects (for example boundary barrier) may be detected from minimum

1.5m away unable to detect at nearer.

3. Besides there are some materials unable to be detected even in detection range as follows.

(1) Needles, ropes, rods, or other thin objects.

(2) Cotton, snow and other material absorbing ultrasonic wave

(for example, fire extinguisher device covered with snow)

4. Reversing toward the sloped walls.

5. Reversing toward the sloped terrain.

6. False alarm may operate in the following condition: irregular road surface, gravel road, sloped road and grass.

Upon alarm generation by grass the alarm may be generated by rock behind grass. Always visually check the area
behind the vehicle before backing up.
The sensors cannot discriminate between materials.

7. Sensors may not operate correctly in the below conditions.

Ensure sensors are clean from mud or dirt

(1) When spraying the bumper, the sensor opening is covered with something in order not to be contaminated. If

sensor opening is contaminated with mud, snow, or dirt, detection range will be reduced and alarm may not be
generated under the crash condition. Dirt accumulated on the sensor opening shall be removed with water.
Do not wipe or scrape sensor with a rod or a hard object.

(2) If the sensor is frozen, alarm may not operate until sensor thaws.
