WHAT ARE THE APPLICATIONS OF ADAS?

ADAS usually includes Traffic Message Channel (TMC), Intelligent Speed Adaptation (ISA), Vehicular Communication Systems and other driver assistant systems. The specific systems are as follows:

Vehicle Cab:
1) Lane Departure Warning System

2) Lane Keeping Assist

3) Traffic Sign/Signal Recognition

4) Night Vision System

5) Driver Status Monitor

6) Electric Vehicle Warning

7) Hill Descent Control

Front:
1) Parking Assist

2) Adaptive Front/Lighting System

3) Adaptive Cruise Control

4) Pedestrian Detection

5) Emergency Brake

Rear:
1) Reverse Image

2) Parking Assist

3) Rear Collision Warning

Side:
1) Surround View

2) Blind Spot Detection

WHAT IS ADAS?

The Advanced Driver Assistance System (ADAS) uses image processing cameras, radar, light detection and ranging and other sensors to monitor vehicle surroundings and detect potentially dangerous situations. Purpose: to increase safety through advanced situational awareness and reduce collision possibilities.

Sensors used in ADAS include cameras, radars, lasers and ultrasound. They can detect light, heat, pressure and other variables used to monitor the state of vehicle. Usually they locate in the front and rear bumpers, side mirrors, vehicle cab and wind shield glasses.

WHY IS THE TPMS LIGHT LIT ON THE DASH OF MY 2005 VEHICLE?

The tire pressure control module might be faulty. Use an Autel tool with OBDII-connection capability such as the TS508 or TS608 to detect trouble codes within the TPMS module. You may need to repair or replace a part within the system such as a transmitter or receiver.

MY VEHICLE HAD A COLLISION. NOW MY TPMS LIGHT STAYS ON. WHAT DO I DO?

The vehicle may have a damaged TPMS module or non-functioning sensors or both. Use an Autel TPMS tool to check the sensors and the control module.

If sensors fail to activate, the sensors need to be replaced. Program Autel’s MX-Sensors to replace sensors. Follow the vehicle manufacturer-specific Relearn procedures displayed on your Autel tool. If the sensors fail to relearn, connect the Autel TPMS to the OBDII port to scan for system faults. You may need to repair or replace a part within the system such as a transmitter or receiver.

WHY CAN’T I COMPLETE THE SENSOR RELEARN PROCESS?

Please carefully follow the step-by-step instructions displayed under Relearn Procedure on your Autel tool.

WHY WAS I UNSUCCESSFUL IN RELEARNING IDS. AFTER I PERFORMED AUTO RELEARN AND DROVE THE VEHICLE?

Drive the vehicle consistently at the speed of between 25 km/h and 100 km/h (15 mph and 62 mph) throughout the Relearn process.

Wait at least 15 minutes before starting a second relearn.

WHY DOES THE VEHICLE’S TPMS LIGHT DISPLAY THE MESSAGES “PLEASE CHECK TIRE PRESSURE” AND “LOW-PRESSURE CONDITION”?

1. Ensure the tires’ air pressure is consistent with the vehicle manufacturers recommended pressure. The vehicle tire placard, located on the door jamb of the driver door, will list the recommended air pressure. Check the tires for wear and leakage. It is best to inflate tires when they are cold.

2. Inflate the tires to 10-15 kPa (1.5 to 2 Psi) above the air pressure recommended on the tire placard. Wait 15 minutes and deflate the tire to the recommended pressure. Never inflate the tire more than 30 percent of its recommended value.

It must be noted that:

1) The nominal tire pressure should never exceed the full load pressure, especially vehicles with modified tires; and

2) The vehicle should never be driven with over-inflated tires.

WHY DOES THE TPMS LIGHT DISPLAY “LOW PRESSURE” DAYS AFTER I ACTIVATED THE SENSORS?

Problem description 1:

Sensors are properly mounted and have been successfully relearned to the vehicle. The TPMS light displays a few days later indicating “low pressure”. I activated the sensors and the tires read low pressure.

Solution:

Please double check the valve stems of all sensors to ensure there is no air leak.

Problem description 2:

Clamp-in sensors are properly mounted, but I have trouble dismounting the tires.

Solution:

 

The tire will leak if the washer is not securely mounted against the outer rim. Using the positioning pin, tighten the screw-nut. Do not over tighten.

WHY DOES MY TOOL DISPLAY A “DUPLICATED SENSOR ID” WARNING MESSAGE WHEN I CANNOT COMPLETE THE RELEARN PROCEDURE AND THE TPMS MALFUNCTION LIGHT REMAINS LIT?

The same sensor might have been activated twice and therefore the tool is displaying duplicate IDs.

When activating sensors, follow the procedure displayed on the screen and activate each sensor at the wheel in the order prompted by the display.

Each Sensor on each wheel must have a unique ID. If two sensors display the same ID, you will need to replace the sensor or re-program the MX-Sensor with a unique ID.

WHY DOES THE TPMS LIGHT COME ON AFTER RELEARNING THE SENSOR IDS, VIA THE OBD RELEARN PROCESS, AND AFTER DRIVING THE VEHICLE FOR THE TIME AND AT THE SPEED ADVISED IN THE RELEARN PROCEDURE?

Solution:

Activate the sensors and ensure they are functioning and can be read.
