The TDB003 Proximity Smart Key System Tester is a diagnostic tool designed to test and troubleshoot issues related to vehicle immobilizer systems, specifically those involving smart/proximity keys. It offers a comprehensive suite of tests to ensure the proper functioning of various components within these systems.
Function Description:
The primary function of the TDB003 is to diagnose problems within a vehicle's smart/proximity key system. This includes testing the transponder key, remote control operation (both Radio Frequency (RF) and Infra Red (IR)), external and internal vehicle antenna transmitters, and the transponder antenna. The device is capable of displaying signal levels, frequency measurements, and signal waveforms, providing a detailed insight into the system's performance. It also incorporates scan modes for a more in-depth analysis of proximity/smart key system signals.

Usage Features:
The TDB003 is designed for ease of use with a clear menu-driven interface and intuitive controls.
- User Interface: The device features an LCD screen for displaying test results, signal waveforms, and menu options. Navigation is done using UP, DOWN, and OK buttons.
- Power Control: The device is turned on by pressing the ON button and turned off by pressing it for 2 seconds.
- Antenna Locations: The manual clearly identifies the locations of various receiving antennas on the device:
- Infra Red (IR) Remote Control Receiver (top of the device)
- Vehicle Transmitter Antenna (right side of the device)
- Transponder Key Antenna (middle slot/area)
- Radio Frequency (RF) Remote Control Antenna (base of the device)
- Standard Transponder Key Test:
- Select "TRANSPONDER TEST" from the main menu.
- Place the key in or on the key slot.
- The TDB003 detects the transponder and displays its operating frequency (e.g., 125KHz).
- Some remote keys may require specific horizontal, vertical, or in-slot placement for detection.
- Remote Control (RF) Testing:
- Select "REMOTE RF TEST" from the main menu.
- Place the remote key close to the base of the TDB003 (RF antenna location).
- Press each button on the remote to test.
- The TDB003 displays the remote control's frequency and signal level on a bar graph.
- Remote Control (IR) Testing:
- Select "REMOTE INFRA RED" from the main menu.
- Point the remote at the IR receiver (top of the device).
- Press each button on the remote control.
- The TDB003 indicates if an IR signal is received.
- Transponder Coil Antenna Testing:
- Select "COIL ANTENNA TEST" from the main menu.
- Hold the center of the TDB003 close to the vehicle's ignition.
- Insert the transponder key and switch the ignition ON.
- The TDB003 indicates communication between the car and key with a series of beeps.
- Important Note 1: For some vehicles (e.g., Ford, Mazda), the ignition antenna transmits only once when the key is turned. The key must be removed, and a 30-second wait is required before it will transmit again upon turning the key.
- Important Note 2: The transponder coil antenna is in the center of the tester. If no signal is received, turn the tester so its back faces the antenna.
- Proximity/Smart Key System Full Testing:
- Select "PROXIMITY FULL TEST" from the main menu.
- Hold the proximity remote at the base of the unit (RF antenna).
- Place the TDB003 vehicle transmitter antenna close to the proximity transmitter on the vehicle (e.g., door handle).
- Operate the proximity system (touch sensor, press button, open door).
- The TDB003 provides visual and audible signals indicating the signal level of both the vehicle transmitter and the proximity remote key.
- It also displays the frequency of the proximity remote signal.
- Sensitivity can be adjusted using the UP and DOWN buttons if the signal is difficult to read.
- Proximity/Smart Key System Scan Modes:
- PROX FULL SCAN MODE: Displays a rolling signal waveform showing both key and car signals.
- PROX KEY SCAN MODE: Displays a rolling signal waveform showing only the key signal.
- PROX CAR SCAN MODE: Displays a rolling signal waveform showing only the car signal.
- Sensitivity can be adjusted in all scan modes using the UP and DOWN buttons.
- Oscilloscope Mode:
- Allows viewing and comparing the signal level of smart/proximity keys.
- Offers two modes: SLOW and FAST, for different frequency smart keys.
- Measurement sensitivity can be adjusted using the UP and DOWN buttons.
- Settings Information:
- Accessed via "SETTINGS" in the main menu.
- Sounder Control: Allows selecting audible feedback for:
- Proximity/Smart Key ON
- Vehicle Proximity Sensor ON
- OFF
- Only one option can be selected at a time.
- Prox Sensitivity: Increases the pick-up of the proximity sensor.
- Note: For some models (e.g., Chrysler), sensor signals are smaller, and enabling "HIGH" setting helps receive a better signal.
- Audible Signal Indication: Provides audio feedback during various tests.
Maintenance Features:
- Battery Replacement: The manual provides clear instructions for inserting and replacing the 4 AAA batteries by sliding the cover to expose the battery compartment.
The TDB003 is a versatile and essential tool for automotive technicians and locksmiths dealing with modern vehicle immobilizer and keyless entry systems, offering a clear and efficient way to diagnose complex electronic issues.
