Check intermediate
connector D-111, and repair if necessary. If intermediate connector
is normal, check and repair harness between B-05 (terminal No. 1) manifold
absolute pressure sensor connector and D-213 (terminal No. 80) engine-ECU
connector.

Replace the engine-ECU. When the
engine-ECU is replaced, write the chassis number (Refer to GROUP 00 -
Precautions Before Service - How to Perform Chassis Number Writing ). After replacing the
engine-ECU, register the injector identification code and learn fuel
injection (Refer to GROUP 00 - Precautions Before Service -
What The Common Rail Engine Learns ).
