INSPECTION PROCEDURE
Go to CAN communication system for troubleshooting (See page Нажмите здесь).- УКАЗАНИЕ:
- When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system before repairing each corresponding sensor.
- Read freeze frame data using an intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
- If the CAN communication system malfunctions, there is no data output from the ECM. In this case, some of the freeze frame data are not correct and not identical to the ECM data, however, the ECM data are correct.
