What it does
Uses high current to rotate the engine. Control-circuit and cable faults can imitate motor failure.
A component is one possibility inside a larger system. Confirm its inputs, outputs, connections, and any bounded planning context before replacement.

Follow the sequence, stop when evidence changes the path, and verify the exact vehicle information before acting.
Where it is located
Location and access vary by platform, engine, drivetrain, market, and installed equipment. Identify the exact component using the vehicle’s service information before disconnecting or removing anything.
Symptoms are clues—not proof
Start with the system symptom and operating conditions. A failed connection, control input, related component, incorrect prior repair, or mechanical condition can imitate component failure.
Use the exact safety procedure
Confirm isolation, support, pressure, temperature, and stored-energy hazards for the vehicle before testing.
Testing focus
