Model information:
2012 Hyundai Sonata
Function description:
Tire pressure sensor learning guide after tire pressure sensor replacement
Using tools：
CRT 701 (This operation takes CRT 701 as an example. For the specific operations about other tire pressure devices of Launch, you can refer to this method.)
Sensor OE number：
(Continental) 529331J000
Device version information:
V10.32 and later version information in the upper left corner of the menu.
Fault description:
The instrument panel illuminates the tire pressure warning light, as shown in the following figure.
Procedure:
1. Select Launch[CRT711], select the [Tire Pressure System] function, and select the corresponding menu based on the information on the vehicle nameplate:
Hyundai→Sonata→[2010/01-2013/12(433MHZ)]
Activate the tire pressure sensor inside the tire and find that the left front tire cannot be activated (activation failure indicates sensor damage and
needs to be replaced).
2. Click on the [Programming] function above, then select [Auto] to program one LTR-Sensor.
(Note: Here, you can also choose [Manual] to input the original vehicle sensor ID or select [Copy ID by OBD]. The sensor programmed using this method does not require [Relearn] and can be directly installed for road testing. After cloning, the original vehicle sensor must be thrown away and cannot be placed on the vehicle to prevent data interference with the tire pressure light.)
3. Install the programmed sensor into the vehicle to replace the damaged tire pressure sensor, as shown in the following figure.
4. Click the [Activate] function again to activate the left front tire pressure sensors, as shown in the following figure.
5. Click on the [Learning] function above, then click on the [OBD relearning] button at the bottom right, as shown in the following figure. (Note: OBD learning is to write the sensor ID and position of the activation interface into the vehicle's tire pressure computer.)
6. Sensor learning successful.
7. Click on the [Activate] interface again, and then click on the [Read ECU ID] in the bottom right corner to confirm whether the ID has been successfully learned (note: if the ID position is correct, the font color will be black, and if the position is incorrect, the font will be red), as shown in the figure.
8. Select [Diagnose] and then click [Read DTC]. If the car still has a fault code, it is necessary to clear the fault code, as shown in the following figure.
9. Increase the pressure of all four tires to 240 kpa, and the customer conducted a 15 minute road test at a speed of 30km/h or above. There were no abnormal tire pressure alarms, and the problem was resolved.
