Toyota 2kd-ftv Ecu Pinout Diagram -

A: Partially. With the ignition ON, measure resistance between CANH and CANL on the harness side . You should read 60 ohms (if two 120-ohm terminating resistors are present). If you read 120 ohms, one resistor is broken. If you read open, the bus is dead.

A: Unlikely. Check Pin A3 (BATT) for constant 12V. If this has 0V, the ECU lost its "Keep Alive Memory." Fix the 10A "ECU-B" fuse in the cabin box. toyota 2kd-ftv ecu pinout diagram

Wiring colors and pin locations vary by chassis number (e.g., GUN125 vs. KUN25). Always verify with a continuity test before splicing. Modifying your ECU may violate emissions laws in your region. A: Partially
