Model information:
2010 Cadillac SRX
Function description:
Replace the tire pressure sensor to learn the operation guide
Used 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
Sensor OE number:
(Schrader)12768826/20922900/22854866
Fault description:
The abnormal display of left rear tire pressure on the instrument is 0, and the actual air pressure is 240KPa, which is inconsistent with the actual tire pressure and sometimes bad, and the tire pressure lamp is lit, 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:
Cadillac →SRX→[2009/11-2011/12 (315MHZ)] Enter the feature list Select the [Check Sensor] function to activate the four tire pressure sensors of the original car, and it is found that the four sensors cannot be activated (activation failure indicates that the sensor is damaged and needs to be replaced).
2. Go back to the previous level and select the [Program Sensor] function, and then select [Automatic Creation] to program a Launch tire pressure sensor.
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 upper level to select the [Relearn] function, and operate according to the operation prompts. The learning is successful, as shown in the following figure (Note: OBD learning is to write the sensor ID and position of the activation interface into the tire pressure computer of the vehicle)
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 230 kpa, and the tire pressure was tested at 30km/h or above for 15min. No abnormal alarm occurred again, and the problem was solved.
