Model information:
2015 Lexus RX200t
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) 4260748010/426070E020
Fault description:
Replace the tire position; re-match the tire pressure to calibrate the tire ID position, as shown in the figure below.
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 → RX Series →[2015/10-2020/12(315MHZ)] Enter the feature list
Select the [Check Sensor] function to activate the four tire pressure sensors of the original car and determine the location of the current tire ID (If activation fails, the sensor is damaged and needs to be replaced).
2.Return to the upper level, enter [TPMS OBDII], select [Read ID], and find that the location of the vehicle ECU ID is inconsistent with the actual tire location ID (if the location is wrong, the ID number is red, and if it is correct, it is black), the result is as follows:
3. Click "OK" to return to the previous level, then enter the [Relearn] function to relearn the current tire ID position, and operate according to the operation prompts (the instrument pressure value will be refreshed and displayed again), as shown below.
4.Sensor ID learning successfully. (Note: OBD learning is to write the sensor ID and position of the activated interface into the tire pressure computer of the vehicle.)
5.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.)
6. 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).
7. 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.
