Model information:

2018 ES300h


Function description:

Replace the tire pressure sensor to learn the operation guide.


Use tools:

CRT511S (This operation takes CRT511S as an example; the specific operation of other tire pressure equipment can refer to this method.)


Device version information:

V1.23 or later version


Sensor OE number:

(Pacific) 426070E020


Fault description:

A platform purchased a tire pressure sensor to replace the left rear wheel after the road test, the four-wheel tire pressure has been showing abnormal -- how to run without showing the pressure value, as shown in the following figure.

Procedure:

1. Select the Launch [CRT511S], select the function of [Tire Pressure System], and select the corresponding menu according to the information on the vehicle nameplate:

Lexus → ES series →[2018/08-2019/12 315MHZ)] Enter the feature list

Select the [Check Sensor] function to activate the five tire pressure sensors of the original car, and it is found that the five sensors cannot be activated (Determine that there is a problem with the purchased sensor program and replace a left rear sensor).

2. Go back to the previous level and select the [Program Sensor] function, then select [Automatic Creation] to program a Launch tire pressure sensor.

(Note: Here you can also select [Manual Creation] to input the sensor ID of the original car or [OBD copy] sensor ID. The sensor programmed in this method does not require [Relearn] and can be directly installed for road test.)

3. Load the programmed sensor into the car to replace the bad tire pressure sensor, as shown in the following figure.

4. Go back to the previous level and click the [Check Sensor] function again to activate the replaced left rear tire pressure sensor (save it when the device prompts whether to save the activated data, otherwise all sensors need to be activated again) as shown in the following figure.

5. Go back to the previous level and click the [Check Sensor] function again to activate the replaced left rear tire pressure sensor (save it when the device prompts whether to save the activated data, otherwise all sensors need to be activated again) as shown in the following figure.

6. After the sensor is successfully learned, click the "Enter" button to read the ECU ID to determine whether the learning is successful. (Note: If the ID is correctly displayed, the font color is black; if the ID is incorrectly displayed, the font is red).

7. Select the [TPMS OBDII] function on the function selection page, and then select the [Read DTCs] function, as shown in the figure (if there is a fault code, you need to perform the [Clear DTCs] function).

8. The tire pressure sensor was successfully replaced, the indicator tire pressure indicator was turned off, the pressure of all four tires was increased to 250kpa, and the tire pressure was tested at 30km/h or above for 15min. No abnormal alarm occurred again, and the problem was solved.
