X-Analyser can be used for OBD Scan Tool functions based on the OBD Standards (ISO 15031, ISO 15765 and SAE J1979). OBD modules can be set up to perform Mode 1, Mode 3 and Mode 4 Scan Tool functions.
These diagnostics features make X-Analyser the ideal 2-in-1 CAN tool with features for viewing real-time CAN and also for performing standard OBD functions for emissions related ECUs.
OBD Mode 1 – Live Data
X-Analyser can send messages to query any vehicle via the OBD CAN port on which Parameter Identifiers (PIDs) are supported by the vehicle. Once this is done, the PIDs supported can be easily selected via the X-Analyser Signals panel to later display the “Live Data” of these supported PIDs. These functions are accomplished through the X-Analyser’s Object Transmitter functions.
OBD Mode 3– Reading Diagnostic Trouble Codes
X-Analyser can be used for the Scan Tool Mode 3 function Read Current Diagnostic Trouble Codes (DTCs) by sending a diagnostic request to emissions ECUs. This is done utilising an Object transmitter message. If any DTCs are active then the DTC values will be reported by X-Analyser.
OBD Mode 4–Clearing Diagnostic Trouble Codes
X-Analyser can send a standard diagnostic CAN message that commands the emissions related ECUs to clear their DTCs. This is verified by the resending of the Mode 3 message showing the response of no DTCs.
