TECHMATE Signal Tech IIUser GuideTPMS OperationSSignal Tech II TPMS Registration MethodThe Signal Tech II activates all four Sensors, captures the Sensor IDs then writes the Sensor IDs directly to the ControlUnit, unlike CIII that places the vehicle in “Learn” mode and “Listens” for the Sensor IDs as they are activated by J-45295Valve Activation tool. The vehicle’s antenna then receives the Sensor IDs and they are written to the Control Unit.Nissan and Infiniti Vehicle Testings sALWAYS:3 Check the for the Indicator LightqA Flashing light means a system faultA Solid Light means low pressure3 Adjust the tire pressure per tire placardq3q Test the Left Front (LF) sensor first3 Work CLOCKWISE around the carq3 Connect to OBDIIq3q Print a report for your recordsStartEndUse the following steps to Diagnose TPMS Nissan / Infiniti Vehicles1.

The screen of the tool will now prompt you “Press toolagainst LF tire and press OK to activate”.a.Hold the Signal Tech II on the Tire, along side ofthe Wheel, where the Valve Stem is located.(Do not hold on the wheel, as this can effect theperformance of the tool)b.With the tool held at a 0 to 15 degree angle to thetire, press and release the OK button to activatethe sensor as shown below. You will need to holdthe tool steady until the test is completed. TheScreen will show “Search for Schr. TPM” andwill show Searching Data. A Status Bar will cycleacross the bottom of the screen.d. The Tool will Prompt for 3 attempts for asuccessful read before displaying a NO TPMFOUND message, and indicating as so withan X as shown below. The tool will also giveone audible beep. Continue to the OBDcommunications to confirm DTCs. If a sensoris not communicating, a corresponding DTCshould be stored.e.c.If the Incorrect TPM sensor type is found by thetool, the Signal Tech II will indicate the situationwith a ? at that wheel position as shown. Thetool will also give 3 audible beeps to indicatewrong sensor type. Ensure that the correctsensor is installed. Continue to the OBDcommunications to confirm DTCs. If thesensor type is incorrect, a correspondingDTC should be stored.As you activate the sensors, the tool will displaypressure at each wheel location and auto cycleyou to the next on a successful read. The toolwill give an audible sequence of beeps.NOTE: If an ‘X’ or ‘?’ appears, the DTCs can still beread but the ID registration will not complete.5

Once all 4 positions are activated, the tool willscroll to the CON OBD box.a. If you haven’t done so already, connect theOBD cable to the base of the tool at theDB15 connection.b. Connect the OBD cable to the port on the vehicleand turn the ignition to the ON position6
TECHMATE Signal Tech IIUser GuideTPMS OperationS Cont.8. Once the tool is connected, the tool will display COMMS, press OK to continuea. If you are connected, and the display does not change, disconnect and try again.This feature is detecting power on the DLC and will not change until there is agood connection and the ignition is in the On position.9. The tool will connect to the BCM (control unit), read the VIN, read sensor IDs and checkfor TPMS DTCs. If DTCs related to TPMS are found, the tool will display them. WhenDTCs are displayed, further diagnosis may be required. If “Low Press” is displayed,this indicated that low tire pressure was detected in the past or is currently detected.This is normal operation of the TPMS system. Tire pressures must be verified andcorrected accordingly.DTC Screen:ID ComparedTo BCMPosition ComparedTO BCMStored FilesDTC if anyWheel positionaccording tothe toolPress to Write IDsor Clear DTCsWrite IDs or Clear DTCsDTCs are shown in the actual wheel position as found by the tool.The tool compensates for tire rotations.a.

TECHMATE Signal Tech IIUser GuidePrinting the Audit Report1. To print the Audit Reporta. Connect the USB cable to the PCb. With the tool still on, connect theUSB cable to the Signal Tech IIc. Open “My Computer” and locate the Signal Tech IIat “Removable Disk (x:)”d. The current vehicle report will be under“Removable Disk x:” with the name CURR REPe. Click on the reports folder to view savereports by VIN number.f. Locate the html file.g. Double click to open the html file.h. Complete the form and print.Note:At any point an audit report can be generatedduring the TPMS Check process.Note:If the VIN could not be read by the tool, the reportwill be stored as the CURR REP temporarily or inthe No VIN folder permanentlyPrinting1. To print the report click the “print” button onyour browser.9
TECHMATE Signal Tech IIUser GuideUnderstanding the Audit Report1. The audit report is meant to record all of the necessary information required to determine if maintenanceis required or further diagnosis and repair is needed. It also records the print date and VIN when possible.If a warranty repair is necessary, the report should be kept on file.Comments: It is clear from the above Audit Report that the Left Rear tire was Rotated to theRight Front and the Right Front Tire was Rotated to the Left Rear position.2. If part replacement is required, the suspect sensor can be matched to the audit report. The sensor ID is displayedin two formats on the audit file, Hex and Dec. The sensor ID is printed on the sensor itself. The ID format dependson the sensor manufacturer. Examples are shown below.WheelTool ID HexTool ID DecDTCs*Left Front00345D373431735C1704 - LF Low PressureRight Front00345CFC3431676NoneRight Rear003486BB3442363C1706 - RR Low PressureLeft Rear00B8FF8202176109C1705 - RF Low PressureC1709 - RF No Data10
