Circuit/System Testing
WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. 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.
- Ignition OFF, disconnect the harness connector at the infrared transmitter.
- Ignition OFF, test for less than 5.0 Ω between the ground circuit terminal 12 and ground.
- If greater than specified range, test the ground circuit for an open/high resistance.
- Ignition ON, test for B+ between the accessory voltage circuit terminal 4 and ground.
- If less than specified value, test the accessory voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear seat audio module.
- DVD playing, test for 0.75-2 volts between the remote infra red signal (+) circuit terminal 8 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.
- Test for less than 1 volt between the remote infra red signal (-) circuit terminal 16 and ground.
- If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
- Ignition OFF, reconnect the harness connector at the infrared transmitter, disconnect the X3 harness connector at the radio.
- Ignition ON, DVD playing, test for 4-5.5 mV AC between the remote infra red signal (+) circuit terminal 5 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.
- Ignition ON, DVD playing, test for 4-6 mV AC between the remote infra red signal (-) circuit terminal 13 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.
- Ignition ON, DVD playing, press any button on the remote control aimed at the infrared transmitter. Test for 300-330 MHz between the remote infra red signal (+) circuit terminal 5 and ground.
- If not within the specified range, replace the remote control.
- If all circuits test normal, replace the radio.
