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
1.COLLECT INFORMATION FROM CUSTOMER
Get detailed information from the customer about t he symptom (the condition and the environment when the
incident/malfunction occurred).
>> GO TO 2.
2.TIRE PRESSURE INSPECTION
Check the tire pressure for all wheels. Refer to WT-54, "
Tire Air Pressure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace tire(s) or wheel(s).
3.CHECK LOW TIRE PRE SSURE WARNING LAMP
Check that the low tire pressure warning lamp illumi nates for approximately 1 second after the ignition switch
is turned ON, then turns OFF.
Does the low tire pressure warning lamp turn OFF?
YES >> Inspection End.
NO >> GO TO 4.
4.PERFORM SELF DIAGNOSTIC RESULT
Perform “Self Diagnostic Result”. Refer to BCS-28, "
AIR PRESSURE MONITOR : CONSULT Function (BCM -
AIR PRESSURE MONITOR)" (with Intelligent Key system) or BCS-99, "AIR PRESSURE MONITOR : CON-
SULT Function (BCM - AIR PRESSURE MONITOR)" (without Intelligent Key system).
Are any DTCs displayed?
YES >> Refer to BCS-50, "DTCIndex" (with Intelligent Key system) or BCS-115, "DTCIndex" (without
Intelligent Key system). If two or more DTCs are displayed, refer to BCS-49,
"DTCInspectionPriorityChart" (with Intelligent Key system) or BCS-115,
"DTCInspectionPriorityChart" (without Intelligent Key system).
NO >> GO TO 5.
5.PERFORM DIAGNOSIS APPLICABLE TO THE SYMPTOM
Perform diagnosis applicable to the symptom. Refer to WT-36, "
Symptom Table".
>> GO TO 6.
6.FINAL CHECK
Perform “Self Diagnostic Result” again, and check that the malfunction is repaired. After checking, erase the
self diagnosis memory. Refer to BCS-28, "
AIR PRESSURE MONITOR : CONSULT Function (BCM - AIR
PRESSURE MONITOR)" (with Intelligent Key system) or BCS-99, "AIR PRESSURE MONITOR : CONSULT

6. Hold the Signal Tech II against the side of the left front tire, near the valve stem.
7. 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 s ensor. Once the sensor is acti-
vated, the vehicle parking lamps will flash and the sensor ID will
appear on the CONSULT screen.
8. Repeat steps 6 and 7 for the remaining tires in this order: right front, right rear and left rear.
9. When ID registration is complete, check the following pattern at each wheel.
10. Once all sensors have been activated, select “End” on the CONSULT to finish ID registration.
11. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
Without CONSULT
1. Adjust the tire pressure for all tires to the recommended value. Refer to WT-54, "Tire Air Pressure".
2. Turn on the Signal Tech II tool [- (J-50190) ] and select “TPMS Check” from the main menu.
3. Select vehicle model and year.
4. When prompted, hold the Signal Te ch II 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 release the “OK” button to activate the sensor. Once the sensor
is activated, the tool will sound a tone and the tire pressure will
be displayed.
6. Repeat steps 4 and 5 for the remaining tires in this order: right front, right rear and left rear.
7. When prompted, connect the tool to the data link connector. The tool will connect to the BCM, read the VIN, read sensor IDs and
check for TPMS DTCs. Along wit h DTCs detected, one of the
following will be displayed next to each wheel:
- N/A - Not applicable because no ID found by the tool
- OK - Wheel and sensor ar e in original position
- NEW - New ID found compared to BCM
- RT - Wheel has been rotated
- Low Press - Low tire pressure
8. If no DTC is present or the repair has been complet ed, press the “OK” button to register the IDs and clear
DTCs.
9. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
10. Print a Signal Tech II Audit Report for your records. Refer to the Signal Tech II User Guide for instructions.
