After replacement of tire or road wheel.
NOTE:
ID registration is unnecessary if there are no change in the positions of each wheels (tire pressure sensors) before wheel removal and after wheel installation.
After performing tire rotation.
TPMS ID registration can be performed using one of the following procedures:
Transmitter Activation tool [KV48105501 (NI-45295-A)] using CONSULT (preferred method)
Signal Tech II tool [– (NI-50190)] using CONSULT (preferred method)
Signal Tech II tool [– (NI-50190)] without CONSULT
CONSULT only
TPMS REGISTRATION WITH TIRE PRESSURE SENSOR ACTIVATION TOOL [KV48105501 (NI-45295-A)]
CONSULT
CAUTION:
Always use CONSULT when tire pressure sensor ID registration. (It cannot be ID registration other than with CONSULT).
Ignition switch ON.
Select “ID REGIST” in "Work support" mode of "BCM(AIR PRESSURE MONITOR)".
Select “Start” on “ID REGIST” screen.
Hold the tire pressure sensor activation tool [KV48105501 (NI-45295-A)] (A) against the side of the left front tire, near the valve.
With the tool held at a 0 to 15 degree angle to the tire, press and hold the tire pressure sensor activation tool button until the indicator lamp turns OFF (approximately 5 seconds).
Repeat steps 4 and 5 for the remaining tires in this order: right front, right rear and left rear.
When ID registration is complete, check the following pattern at each wheel:
Sequence | ID registration position | Turn signal lamp | CONSULT |
---|---|---|---|
1 | Front LH | 2 blinks |
“Yet (red)” ↓ “Done (green)” |
2 | Front RH | ||
3 | Rear RH | ||
4 | Rear LH |
After the ID registration procedure for all wheels is complete, press “End” on the CONSULT to finish ID registration.
Test drive the Nissan Pathfinder vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
TPMS REGISTRATION WITH SIGNAL TECH II TOOL (NI-50190)
NOTE:
The Signal Tech II must be updated with the newest software version in order to perform the below procedures. The Signal Tech II software updates can only be downloaded from a CONSULT unit with ASIST. Other versions of ASIST will not show the updates.
CONSULT
Adjust the tire pressure for all tires to the recommended value. Refer to Tire Air Pressure.
Ignition switch ON.
Select “ID REGIST” in "Work support" mode of "BCM(AIR PRESSURE MONITOR)".
Select “Start” on “ID REGIST” screen.
Turn on the Signal Tech II tool (NI-50190).
Hold the Signal Tech II against the side of the left front tire, near the valve.
With the tool held at a 0 to 15 degree angle to the tire, select “Activate Sensor” from the main menu, then press and release the “OK” button to activate the sensor. Once the sensor is activated, the Nissan Pathfinder vehicle parking lamps will flash and the sensor ID will appear on the CONSULT screen.
