D56-27 (D) - Body ground	Ignition switch ON Shift lever not in D	Below 1 V

HINT:

*: The voltage will drop slightly due to turning on the back-up light.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)

Disconnect the A27 ECM connector.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• 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.
