Circuit/System Testing

2006 Chevrolet Suburban K2500, 6.0 USECTION Circuit/System Testing
WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Test or replace the remote batteries before performing the circuit/system test.
  1. Ignition OFF, disconnect the harness connector at the infrared transmitter.
  2. Ignition OFF, test for less than 5.0 ohms between the ground circuit terminal 12 and ground.
    • If greater than specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, DVD playing, test for B+ between the infrared module control circuit terminal 4 and ground.
    • If less than specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear seat audio module.
  4. Ignition ON, DVD playing, test for 0.75-2 volts between the remote infrared signal (+) circuit and ground.
    • If less than specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
    • If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
  5. Ignition ON, DVD playing, test for less than 1 volt between the remote infrared signal (-) circuit and ground.
    • If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
  6. Reconnect the harness connector at the infrared transmitter, and disconnect the X3 harness connector at the radio.
  7. Ignition ON, DVD playing, test for 4-5.5 mV AC between the remote infra red signal (+) circuit and ground.
    • If less than specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the infrared transmitter.
    • If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the infrared transmitter.
  8. Ignition ON, DVD playing, test for 4-6 mV AC between the remote infra red signal (-) circuit and ground.
    • If less than specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the infrared transmitter.
    • If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the infrared transmitter.
  9. Ignition ON, DVD playing, press any button on the remote control aimed at the infrared transmitter and test for 300-330 MHz between the remote infra red signal (+) circuit and ground.
    • If not within the specified range, replace the remote control.
  10. If all circuits test normal, replace the radio.

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.
