Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Detection Area
- Test condition - PVC pole (Diameter 75 mm, Length 1 m) & At the room temperature
- Distance tolerance (measured at the front of sensor)
81 cm ~ 120 cm : ± 15 cm
41 cm ~ 80 cm : ± 10 cm
Below 40 cm : ± 10 cm
- Below 30 cm may not be detected.
- Sensing zone specification
Sound pulse has a fixed duration.
Pause between pulses is related to the distance from the obstacle and is not variable.
Although the position of the obstacle is not moving during sometime, the buzzer should keep warning. And although an obstacle that is currently warned is getting far, the buzzer should keep warning according to obstacle distance.
The warning sound is generated by the algorithm of ECU which measures the distance of the obstacle from the sensor.
The distance is divided into three detection ranges. Obstacles below 30 cm from the sensor may not be detected.
Each Warning Zone Hysteresis Function for buzzer and display.
| Condition | 1st Warning (120 cm) | 2nd Warning (80 cm) | 3rd Warning (40 cm) |
| the distance between vehicle and obstacle is getting close | Immediately warning | ||
| the distance between vehicle and obstacle is getting far | 2 sec warning delay | 2 sec warning delay | 1 sec warning delay |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
