*GENERAL RADIO DIAGNOSIS

CONDITIONPOSSIBLE CAUSESCORRECTION
General Problems
RADIO WILL NOT TURN ON/OFF WITH IGNITION/NO POWER1. Blown fuses on the back of the radio or in the interior fuse box.1. Diagnose reason for blown fuse (short to ground in the circuit before the radio).
2. No power to fuse.2. Open, short to ground to fuse panel.
3. Sufficient voltage to radio, but sill inoperative3. Install a known good radio, if the condition is gone replace the radio.
NO AUDIO OUTPUT1. Faulty speakers1. Diagnose Speaker circuits, power and grounds
2. Faulty amplifier2. Diagnose Amplifier power supply and grounds
POPPING AND/OR CRACKING NOISE HEARD FROM SPEAKERS1. Antenna.1. Check antenna continuity, antenna ground connections, the antenna signal circuit integrity.
2. Speakers2. Tune receiver to a known good station, if noise is gone the speakers are not the cause. If noise is still present, check speaker power and ground circuits.
DISPLAY IS DIM OR BLACK1. No or low power to the radio.1. Blown fuses on the back of the radio or in the interior fuse box. Diagnose reason for blown fuse (short to ground in the circuit before the radio).
NO STEERING WHEEL CONTROLS1. Switches1. Diagnose the switches and the circuits between the switches and the radio. Check the circuits for opens, excessive resistance, or a short to ground.
SERIAL CODE DOES NOT WORK1. Incorrect code1. Call the Star Center for correct Serial code.
2. A faulty radio can not cause this issue.
INTERMITTENTLY CUTS OUT1. Need to determine what cuts out: the sound, the CD drive, the AM/FM reception, Amp, or the speakers.
WEAK SOUND1. Antenna1. Check antenna continuity, antenna ground connections, the antenna signal circuit integrity.
2. Speakers2. Tune receiver to a known good station, if some stations are louder than others the speakers are not faulty. If noise is weak on all channels, check the speaker power and ground circuits.
3. Amplifier3. Check the Amplifier power and ground circuits for opens, excessive resistance, or a short to ground in the power supply. If the circuits are not faulty, install an known good amplifier.
PHYSICAL DAMAGE1. Defective unit1. Replace the unit: Radio, Amplifier, Antenna, Speaker
UNIT (AMPLIFIER) LIGHTS ARE ON BUT NO SOUND IS HEARD1. Amplifier/speakers1. Amplifier was faulty and replaced and no noise is coming out of the speakers. The speakers may need to be replaced because DC voltage may have ran through the amplifier and damaged the speakers.
UNIT (AMPLIFIER) DOESN'T RESPOND WHEN POWER IS PRESSED1. Amplifier/speakers1. Amplifier was faulty and replaced and no noise is coming out of the speakers. The speakers may need to be replaced because DC voltage may have ran through the amplifier and damaged the speakers.
NO SOUND1. Blown fuses on the back of the radio or in the interior fuse box.1. Diagnose reason for blown fuse (short to ground in the circuit before the radio).
2. No power to fuse.2. Diagnose reason for blown fuse (short to ground in the circuit before the radio).
3. Sufficient voltage to radio, but sill inoperative3. Install a known good radio, if the condition is gone replace the radio.
4. Amplifier/speakers4. Amplifier was faulty and replaced and no noise is coming out of the speakers. The speakers may need to be replaced because DC voltage may have ran through the amplifier and damaged the speakers.

Turn the ignition off.

Disconnect all jumper wires and reconnect all previously disconnected components and connectors.

Note. If the SKREEM or the PCM was replaced, refer to the service information for proper programming procedures.

If the Body Control Module was replaced, turn the ignition on for 15 seconds (to allow the new BCM to learn VIN) or engine may not start.

Program all RKE transmitters and other options as necessary.

With the scan tool, erase all Diagnostic Trouble Codes (DTCs) from ALL modules. Start the engine and allow it to run for 2 minutes. Operate all functions of the system that caused the original complaint.

Ensure that all accessories are turned off and the battery is fully charged.

Turn the ignition off and wait 5 seconds. Turn the ignition on and using the scan tool, read DTCs from ALL modules.

Are any DTCs present or is the original complaint still present?

Are any DTCs present?

YES
