1A-38 Engine General Information and Diagnosis:
Troubleshooting for 1.DEF: Offset at minimum threshold
Check the fuel pressure sensor connectors.
Check the ECM connections.
Repair if necessary.
Check the following connections for continuity and make sure there is no interference resistance:
• Between "C84-2" wire of fuel pressure sensor connector and "C86-32" terminal of ECM connector
• Between "C84-3" wire of fuel pressure sensor connector and "C86-48" terminal of ECM connector
• Between "C84-1" wire of fuel pressure sensor connector and "C86-46" terminal of ECM connector
Repair if necessary.
With ignition switch ON and the engine stationary for more than one minute:
• Check for fuel pressure sensor output voltage between "C84-2" and "C84-1" wire of fuel pressure sensor
connector.
– If the voltage is above 0.5V, the sensor is in order.
• In this case, substitute a known-good ECM and recheck.
– If the voltage is below 0.5V, replace the fuel pressure sensor with common rail referring to "Common Rail
(High Pressure Fuel Injection Rail) Removal and Installation: in Section 1G".
DTC P0201: Fuel Injector Circuit / Open Malfunction-Cylinder 1
CAUTION
!
• This fault can result in a rapid and significant fouling of the diesel particulate filter.
• This fault may appear if the wiring harness has been damaged.
Follow the procedure described in "Electrical Circuit Inspection Procedure: in Section 00 in related
manual".
• This test enables the condition and the conformity of the engine wiring harness to be checked.
NOTE
• Cylinder number is counted from flywheel side.
• Conditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine has been started.
• If CC.1, CC, or 1.DEF is present, the Red stop warning light (gravity 2 warning light) is lit.
• If CO is present the Injection warning light (gravity 1 warning light) is lit.
• If CO is still present, the Malfunction indicator light (MIL) will come on after three consecutive
driving cycles (starting +5 seconds + turn OFF ignition switch and wait 40 seconds.).
• If the fault is present, the injection on cylinder 1 is disabled.
• Use service wire for all operations on the ECM connectors.
