Pinout Values and Diagnostic Parameters
ECM Harness Connector Terminal Layout
ECM Terminal and Reference Value
Preparation
ECM located in the engine room passenger side behind reservoir tank.
ECM Inspection Table
Specification data are reference values and are measured between each terminal and ground. Pulse signal is measured by SDT.
CAUTION: Never use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
