Model information:
2021 Malibu XL
Function description:
Tire pressure sensor learning guide after tire pressure sensor replacement.
Using tools：
CRT 711 (This operation takes CRT 711 as an example. For the specific operations about other tire pressure devices of Launch, you can refer to this method.)
Sensor OE number：
(Schrader) 13516165
Device version information:
V10.32 and later version information in the upper left corner of the menu.
Fault description:
The left rear tire pressure shows abnormal 0 air pressure (the actual pressure is 230 kpa), and the tire pressure light is on, as shown in the following figure;
Procedure:
1. Select Launch [CRT711], then select the [Tire Pressure System] function, and select the corresponding menu based on the information on the vehicle nameplate:
Chevrolet → Malibu →[2019/01-2021/12(433MHZ)]Enter the activation function and ECU ID reading function page.
Activate the four tire pressure sensors of the original car and find that the left rear sensor 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. )
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 rear 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 successfully.
7.After successful learning, clicking [OK] will automatically switch to the [Read ECU ID] page to compare IDs; You can also manually 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 240kpa, 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.
