Such disconnection willerase the memorized information in ECM memory.* Malfunction code stored in ECM memory can be checked bythe special tool.* Before checking malfunction code, read SELF-DIAGNOSISFUNCTION “USER MODE and DEALER MODE” (4-16 to-18) carefully to have good understanding as to what functionsare available and how to use it.* Be sure to read “PRECAUTIONS IN SERVICING” (4-3)before inspection and observe what is written there.• Remove the left frame cover.
