BASIC INSPECTION
Before performing the inspection of FTS, make sure that the follwing items :
Contact resistance, corrosion, bent or broken terminals, loose wires, crack, damage etc.
Crack or damage
Fuel temperature sensor check
Remove the FTS
Connect the ohmmeter probes to the terminal 1 and the terminal 2 and measure the resistance
- Replace the FTS if there is no continuity
Specification : 2.3 ∼2.6 ㏀ at 20℃(68℉)
For checking the FTS current data with the scan tool or resistance value, The resistance will be decreased as the heat increase, the resistance remains unchanged, Replace the FTS
SIMU - SCAN FUNCTION IN THE SCAN TOOL (SIMV)
The SIMU-SCAN feature is capable of generating simulated voltage, frequency, and duty cyle that can be used for in-depth diagnosis while displaying current The SIMU-SCAN also allows raw and current data to be displayed simultaneouslyinformation. This test is to inspect whether or not ECM receives the output signal normally from the sensor by using a SIMU-SCAN function of the scan tool indirectly. At the same time, user is able to check the open circuit and the short circuit to ground through a scantool simulation function indirectly.
CONNECTION METHOD
① Connect to the DLC cable 16 pins to the scantool
② The probe in channel B should be connected in order to input signals for the simulation of voltage
③ Select SIMU-SCAN in Hyundai vehicle diagnosis which allows sensor outut generation and current data analysis to be performed simultaneosly
HOW TO OPERATE
Pressing this key activites sensor output Voltage simulation. The voltage generated through channel B can be set using the (+) and (-) keys in 20 ㎷ steps. If the set voltage and the applied voltage differ by less than 10%, voltage feed back control is maintained by scantool.
If the difference voltage exceeds 10%, the follwing message is displayed and no voltage output occurs. " SIMULATION SIGNAL IS DISTORETED CHECK PROBE, PRESS [ENTER] "
