Diagnostic ProcedureEBS01KDO
1.PERFORM FUEL PUMP LEARNING VALUE CLEARING
NOTE:
If the DTC is detected because of air mixed with fuel (i.e.: caused by lack of fuel), it may become normal by
performing following procedure.
With CONSULT-II
1. Turn ignition switch ON.
2. Perform Fuel Pump Learning Value Clearing. Refer toEC-24, "
Fuel Pump Learning Value Clearing".
3. Start engine and let it idle for at least 60 seconds.
4. Select “SELF-DIAG RESULT” mode with CONSULT-II.
5. Touch “ERASE”.
6. PerformEC-86, "
DTC Confirmation Procedure",again.
7. Is DTC detected again?
Without CONSULT-II
1. Turn ignition switch ON.
2. Perform Fuel Pump Learning Value Clearing. Refer toEC-24, "
Fuel Pump Learning Value Clearing".
3. Start engine and let it idle for at least 60 seconds.
4. Erase the Diagnostic Test Mode II (Self-diagnostic results) memory. Refer toEC-27
.
5. PerformEC-86, "
DTC Confirmation Procedure",again.
6. Is DTC detected again?
