V3800-CR-TE4,V3800-CR-TIE4, DM

3. Check the Connector and Wiring Harnesses for Poor Contact

1. Set the key switch to the OFF position, and check the wiring
harness connectors and ECU pins for incorrect connection,
deformation, poor contact or other defects.
Factory Must be free from faulty connection, deformation, poor
specification contact or other defects.
NOTE
• Intermediate connector and wiring harness in head cover
should be checked, they are possible cause.
OK Check the wiring harness and connector of P-GND terminal (ECU
terminals B-3 and B-4). → Repair.
NG Check the injector wiring harnesses and connectors. → Repair.

4. Measure the Resistance Between Injector Terminals

1. Unplug the injector cable connector of the cylinder indicated by
the DTC, and measure the resistance between injector
terminals (1) and (2).
