DTC Set In Radio With Amplifier
WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
- With the scan tool, verify the DTC is set by the radio.
- Disconnect the suspect audio amplifier harness connector.
- Disconnect the radio harness connector.
- Test for less than 1 volt on both of the suspect low level audio signal circuits.
- If greater than 1 volt repair short to voltage.
- Test for infinite resistance between both low level audio signal circuits and ground.
- If less than specified value, repair short to ground.
- Test for less than 1 ohm between the suspect low level audio signal circuits amplifier harness connector and the suspect speaker harness connector.
- If greater than specified value repair open or high resistance.
- If all circuits test normal, replace the amplifier.
