ENGINE DIAGNOSIS CODE

17–38

Injector circuit malfunction (DTC code P0201 to P0204)

JP31199170601023

Set the starter key to "OFF" and connect the signal check

harness.

Disconnect the ECU side connector of the signal check

harness and measure the resistance between terminals.

Standard value : 2

Ω

or less

Set the starter key to "OFF" and connect the ECU side

connector of the signal check harness.

Start the engine and delete the past failures with the failure

diagnosis tool (HinoDX) using PC.

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.
