Product Information

About this item

• Turn Off CEL: Stop guessing why your Check Engine Light (CEL) or Malfunction Indicator Lamp (MIL) is on. The LAUNCH CR329 OBD2 Scanner helps you quickly identify the cause, read and clear diagnostic trouble codes (DTCs), retrieve VIN information, check I/M readiness status, and monitor your vehicle’s performance in real time—reducing guesswork and avoiding unnecessary repair costs.
• OBDII Protocols and Car Compatibility: The LAUNCH CR329 OBD2 scanner is compatible with most 1996 and newer U.S. vehicles, 2001+ European models, and Asian vehicles that support OBDII protocols, including CAN, ISO9141, KWP2000, J1850 VPW, and J1850 PWM. It works with many cars, light trucks, and SUVs. Powered directly through the OBDII port, this car scanner requires no batteries, charging, or complicated setup.
• Real-Time Vehicle Data: See Your Car's Health Clearly-View live data streams with curve graphs to spot intermittent issues in real time. View and log live data in graph format to monitor R PM, coolant temperature, feul trims, oxygean sensor activity, battery voltage, vehicle speed, and more. Record, graph, replay, and analyze data, or print for detailed troubleshooting.
• Enhanced OBDII Diagnostics: More than a basic engine code reader, the CR329 supports 12V battery health test, O2 Sensor Testing, and EVAP System Monitoring to help evaluate fuel system performance and detect potential emissions-related problems. Monitor vehicle health, optimize the air-fuel ratio to boost fuel economy and cut emissions, saving you money on gas and reducing your vehicle’s environmental footprint.
• Instant DTC Lookup: No Mechanic Jargon. Features a 2.8" HD color screen with built-in DTC code definitions so you understand exactly what's wrong—no Googling required. Just immediate fault code explanations so you can understand issues faster.
• FOR END USER & DIYERS: This error code reader CR329 is “plug and play” and comes with an easy interface. Even if you’re not familiar with vehicle repair, you can quickly take control of this OBD2 scanner and get the information you want.
• The CR329 only supports the diagnosis of emission-related issues. If the engine fault is unrelated to the emission system, it cannot read the engine fault codes. Fault codes can be cleared after resolving the underlying issue. The code reader itself does not have a reset function. The CR329 only supports use with the OBDII interface. If your vehicle has an OBDI interface, diagnosis cannot be performed even if an OBDII adapter is used.
