Circuit/System Testing
2013 Chevrolet Silverado 2500 HD LT, 2D Cab Chassis, 6.6L Eng VIN 8, RWDSECTION Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the appropriate DVD display.
- Ignition OFF, test for less than 5.0 ohms between the ground circuit terminals listed below and ground.
- Ground terminal 6
- Ground terminal 5 (DNU)
- If greater than specified range, test the ground circuit for an open/high resistance.
- Ignition ON, DVD playing, test for B+ between the entertainment remote enable B+ circuit terminal 8 and ground.
- If less than specified value, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
- Ignition ON, test for B+ between the battery positive voltage circuit terminal 7 and ground.
- If less than specified value, test the voltage supply circuit for a short to ground or an open/high resistance.
- Ignition ON, DVD playing, test for 1-8 volts between the video bright control circuit terminal 9, and ground.
- If greater then specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the radio.
- If less then specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
- Ignition ON, DVD playing, test for 0.1-4.0 volts between the video mode signal circuit terminal 10, and ground.
- If greater then specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
- If less then specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
- Ignition ON, DVD playing, test for 1-3 volts between the video signal (+) circuit terminal 1, and ground.
- If greater then specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the radio.
- If less then specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
- If all circuits test normal, replace the DVD display.

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.
