Sensor
The sensor re-read-in read-in procedure must be executed after
each tire change, body control module replacement, or sensor
replacement. Once the reread mode is enabled, the identification
code for each sensor will be read into the body control module
memory. When a sensor identification code is read, the body
control module causes the horn to chirp to indicate that the
sensor has sent an identification code and that it has been
received and read by the body control module. The body control
module must read the sensor identifiers in the correct order to
determine the correct sensor location.
▲The first code read is assigned to the left front position, the
second to the right front position, the third to the right rear
position and the fourth to the left rear position. The turn
signal lights will illuminate separately to indicate the correct
order of the read positions.
①Use the EL-50448 or equivalent to diagnose sensor function
Each sensor has an internal low frequency coil. When tire
pressure monitoring is used in enable mode, a low frequency
transmission signal will be generated to activate the sensor. In
read-in mode, the sensor responds to the low-frequency activation
by transmitting the signal. In Tire Pressure Monitor Read-In
Mode, when the Body Control Module receives a Read-In Mode
transmission signal, it assigns the sensor identification code to
the vehicle location corresponding to its read-in sequence.
②Sensor Function - Using the Pressure Increase/Decrease Method
In standstill mode, each sensor takes a pressure measurement
sample every 30 seconds. If tire pressure increases or decreases
by more than 8.3 kPa (1.2 psi) from the last measurement, a
re-measurement will be taken immediately to confirm the pressure
change value.
Synopsis:
This is a tire pressure reset instrument, or learning motion.
After each tire shift, tire, body control module, and tire
pressure sensor replacement, the sensor re-matching procedure
must be performed to ensure the correctness of the tire pressure
value acquisition display.
Operation steps:
1. Make sure the vehicle is in the TPMS learning state/mode.
2. Follow the automotive maintenance procedures, holding the
instrument in order (left front, right front, right rear, left
rear), aligned with the valve core lever (the mouth of the )
near the tire sidewall to press the reset button.
3. At this time the green LED light (TX light) will light up,
that is, to send a signal, when you hear the car beeps after that
is a successful match.
4. Match other tires in turn.
EL-50448 instructions:
EL50448 works on all General Motors products manufactured for the
North American market. It won't work if you've purchased
aftermarket sensors that are the wrong frequency. EL50448 fit for
G.M most kind of vehicles, equipped with a 315 or 433 MHz Tire
Pressure Monitoring (TPM) system. This re-learn procedure can be
performed by using special tool EL-50448.
How to use EL 50448 TPMS Activation Tool
Step 1- Enter leaning mode
Set the gearshift lever to "P"
Put the ignition switch to “ON”
Enter the interface of tire pressure display by DIC
DIC shows "Press Set / Ctrl to re-learn"
Press “Set / Ctrl”
The turn signal is lighted for 3 seconds and the horn beep sound
twice to enter the learning mode
Step 2- Read tire pressure sensor information
Start from the front-left wheel,
Make the J-46079 or Diagnostic Tool EL-50448 antenna up against
the valve core position & close to the rim of the tire sidewall
El-50448 tire pressure tool starts by the start switch
Successful to read the tire pressure sensor information when the
horn bleeps once
Step 3- Same method to read other tire pressure information
Follow the instuction above to read tire pussure of the
front-right, rear-right, rear-left wheels.
Turn signals is lighted for 3 seconds and the horn bleeps twice
when the learning is complete.
For certain vehicles equipped with a Tire Pressure Monitoring
(TPM) system, a "Sensor Re-Learn Procedure" must be performed
after tire rotations, Remote Control Door Lock Receiver Module
replacement or Tire Pressure Sensor replacement. This re-learn
procedure can be performed by using special tool 50448
EL-50448 Customer Questions & Answers:
Q1: Which GM automobiles will EL-50448 TPMS work on?
A1: Only GM vehicles around 2003 to present.
Q2: Will it work on a expedition xlt 2006 , thanks
A2: No, this is for General Motors vehicles only.
Q3: Does it work on B-MWs?
A3: It worked on my B-MW motorcycle, which uses S-chrader brand
TPMS sensors in the tires, so I would guess the B-MW auto would
be the same. There are some weird tricks you will need to look
up, for example, on my Suzu-ki automobile, you have to follow a
procedure including which tire to start out at and which one you
end at,so I am sure it must be similar for B-MW.
Q4:Why does it not work even after the green light is on?
A4:Make sure that you hold the instrument in order (left front,
right front, right rear, left rear) and press the reset button
against the tyre's sidewall near the valve core lever (the port
where the air is added).
Troubleshooting:
1. make sure it is equipped with a 315/433MHz tyre sensor and is
using a fresh 9v battery.
2. Make sure the antenna is ed in the correct position.
3. please make sure the front tyre is flat and your tyre sensor
is fully charged or in good condition.
4. it is not suitable for heavy trucks with more than 4 tyres.
