[3] Go to measurement of resistance between
injector terminals.
1. Set the starter key to "OFF" and connect the ECU side
connector of the signal check harness.
2. Start the engine and delete the past failures with the failure
diagnosis tool (HinoDX) using PC.
3. If the same failure code is output again, replace the common
rail ECU. If the normal code is output, it is considered that a
temporary error has occurred.
