2.1 READ MODE
· ACTIVE speed sensor:
In this mode, the speed sensor is disconnected from the ECU and connected to
the Jaltest SST device to be able to check it in isolation. By turning the component
whose sensor the user wants to check, they can determine if the sensor generates
a correct signal.
1
Disconnect the speed sensor from the vehicle and connect it to the Jaltest SST
device through multipins according to the IMAGE 1 of the connection diagram
section.
2
Turn on the device and go into Active Sensor Read mode interacting with the
selection button of the mode (1) according to the presses described in the function
table on page 6. The Active Sensor LED must be on, as well as the LED of the errors
that may appear.
3
Turn the component whose sensor you want to check.
4
Signal check: When the component is turning at constant speed, the status LEDs
of the signal must flash sequentially, clockwise, and consistently.
5
Error check:
ٚ The status LEDs of the signal flash inconsistently: The sensor does not detect a
consistent turn signal.
ٚ The short circuit error LED lights up: Short circuit to power supply has occurred
during the execution of the test.
ٚ The power supply error LED lights up: Incorrect mode has been selected
(simulation).
Note: It is possible to repeat the test with just a short press of the selection button of the mode (1). The
device performs an error reset and starts the test again.
