ToyoSys Scan Lite is a diagnostic scan tool for Toyota, Lexus and Scion vehicles. Read and clear diagnostic trouble codes (DTCs), turn off the Check Engine Light (MIL) after repair, and access OEM enhanced modules: Engine, ECT (Electronically Controlled Transmission), TCM, ABS/VSC/TRC and SRS Airbag. Generic OBD2 services work on any OBD2-compliant vehicle. Requires an ELM327-compatible OBD2 adapter (Bluetooth or Wi-Fi).
★ GENERIC OBD2 (SAE J1979)
• Service $03 / $07 / $0A: read Stored (confirmed), Pending and Permanent DTCs with code definitions
• Service $04: clear DTCs, freeze frame data and reset the MIL
• Service $02: Freeze Frame data recorded when the DTC was set
• Service $01: Live Data / Data Log – all PIDs supported by the ECU, in metric (SI) or English units
• I/M Readiness (smog check): MIL status, DTC count, continuous and non-continuous monitor status
• Service $06: On-Board Monitoring test results (OBDMID/TID) with min/max limits and pass/fail
• Service $05: O2 sensor monitoring test results
• Service $09: vehicle information – VIN, Calibration ID (CALID), CVN, In-use Performance Tracking (IPT)
★ TOYOTA / LEXUS / SCION ENHANCED DIAGNOSTICS
• Engine and Engine & ECT: read current, history and pending DTCs; clear DTCs
• TCM / ECT (automatic transmission): read and clear DTCs
• ABS / VSC / TRC (anti-lock brake, vehicle stability control, traction control): read and clear DTCs
• SRS Airbag (Supplemental Restraint System): read and clear DTCs
• Built-in DTC database with over 6,200 trouble code definitions (P, C, B, U)
★ SUPPORTED PROTOCOLS • ISO 15765-4 CAN (11-bit / 29-bit, 500 kbps) • ISO 14229 UDS on CAN and ISO 14230 KWP2000 (enhanced modules) • ISO 14230-4 KWP2000 (K-Line, 5-baud / fast init), ISO 9141-2 • SAE J1850 VPW and SAE J1850 PWM
★ OBD2 ADAPTERS
• Tested: OBDLink MX/MX+, Vgate iCar, genuine ELM327 v1.5 Bluetooth, ELM327 Wi-Fi • Compatible: OBDLink family, Kiwi family, Vgate family, BAFX and other ELM327 v1.4 or later
• Note: many low-cost "ELM327 v2.1" clones implement only part of the ELM327 command set. They can read generic OBD2 data but cannot reach enhanced modules (ABS, SRS, TCM). For enhanced diagnostics, use an adapter that supports ELM327 v1.4+ commands (custom CAN headers and receive filters).
★ LITE VERSION • Contains ads • Some manufacturer-specific DTC definitions are available in the Pro version
REQUIREMENTS
• ELM327-compatible OBD2 adapter (Bluetooth or Wi-Fi) • OBD2-compliant vehicle (US 1996+, EU petrol 2001+, EU diesel 2004+)
