so check the harness. and check
HARNESS INSPECTION
Check for an open or short circuit in the harness b etween the terminals which were defective according
to the connector measurements. Carry out this inspe ction while referring to Volume 2 Electrical manual.
Here, “Check harness between power supply and termi nal xx” also includes checking for blown fuses.
For inspection service points when there is a blown fuse, refer to “Inspection Service Points for a Blown
Fuse”.
MEASURES TO TAKE AFTER REPLACING THE ECU
If the trouble symptoms have not disappeared even a fter replacing the ECU, repeat the inspection procedure
from the beginning.
