W/L ON HISTORY
• “W/L ON HISTORY” indicates the “TIME” w hen the warning/ indicator lamp is turned on.
• The “TIME” above is:
- 0: The condition that the warning/indicator lamp has been turned on 1 or more times after starting the engine
and waiting for 30 seconds.
- 1 - 39: The number of times the engine was restarted after the 0 condition.
- NO W/L ON HISTORY: No warning/ indicator lamp history is stored.
NOTE:
• W/L ON HISTORY is not stored for approximately 30 seconds after the engine starts.
• Brake warning lamp does not store any history when the parking brake is applied or the brake fluid level gets
low.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
NOTE:
The Signal Tech II Tool (J-50190) can be used to perform the following functions. Refer to the Signal Tech II
User Guide for additional information.
• Activate and display TPMS transmitter IDs
• Display tire pressure repor ted by the TPMS transmitter
• Read TPMS DTCs
• Register TPMS transmitter IDs
SELF DIAGNOSTIC RESULT
NOTE:
Before performing Self Diagnostic Result, be sure to regi ster the transmitter ID or the actual malfunction may
be different from that displayed on CONSULT.

ID REGISTRATION PROCEDURE
DescriptionINFOID:0000000009464492
This procedure must be performed:
• after replacement of a transmitter or BCM (with individual tire pressure display).
• after replacement of a transmitter, BCM or rotation of the wheels (without individual tire pressure display).
Work ProcedureINFOID:0000000009464493
TPMS ID registration can be performed using one of the following procedures:
• Transmitter Activation tool (J-45295-A) with CONSULT (preferred method)
• Signal Tech II tool (J-50190) with CONSULT (preferred method)
• Signal Tech II tool (J-50190) without CONSULT
• CONSULT only
TPMS REGISTRATION WITH TRANSMI TTER ACTIVATION TOOL (J-45295-A)
With CONSULT
1. Turn the ignition switch ON.
2. Using CONSULT, select “WORK SUPPORT” in BC M (AIR PRESSURE MONITOR). Then, select “ID
REGIST.”
3. Select “Start” on “ID REGIST” screen.
4. Hold the transmitter activation tool (J-45295-A) (1) against the side of the left front tire, near the valve stem.
5. With the tool held at a 0 to 15 degree angle to the tire, press and
hold the transmitter activation tool button until the indicator lamp
turns OFF (approximately 5 seconds).
6. Repeat steps 4 and 5 for the remaining tires in this order: right
front, right rear and left rear.
7. When ID registration is complete, check the following pattern at each wheel.
8. After the ID registration procedure for all wheels is complete, press “End” on the CONSULT to finish ID registration.
9. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
TPMS REGISTRATION WITH SIGNAL TECH II TOOL (J-50190)
NOTE:
The Signal Tech II must be updated with software version 1.1.48 or newer in order to perform the below proce-
dures. The Signal Tech II software updates can onl y be downloaded from a CONSULT unit with ASIST. Other
versions of ASIST will not show the updates.
With CONSULT
1. Adjust the tire pressure for all tires to the recommended value. Refer to WT-60, "Tire".
2. Turn the ignition switch ON.
3. Using CONSULT, select “WORK SUPPORT” in BC M (AIR PRESSURE MONITOR). Then, select “ID
REGIST.”
4. Select “Start” on “ID REGIST” screen.
