DIAGNOSTIC TEST
1. CHECK FOR AN INTERMITTENT CONDITION
Turn the ignition on, then off, and then on again.
With the scan tool, read Amplifier DTCs.
Q: Does the scan tool display active: B1462-CHANNEL 1 AUDIO SPEAKER OUTPUT CIRCUIT HIGH?
YES: Go To 2
NO: The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Perform BODY VERIFICATION TEST VER-1. Body Verification Test
2. CHECK FOR VOLTAGE ON THE (X209) AMPLIFIED LEFT I/P SPEAKER (+) CIRCUIT
Turn the ignition off.
Disconnect the Amplifier C2 harness connector.
Disconnect the Amplified Left I/P Speaker harness connector.
Turn the ignition on.
Measure for voltage on the (X209) Amplified Left I/P Speaker (+) circuit.
Q: Is the voltage above 10.0 volts?
YES: Repair the (X209) Amplified Left I/P Speaker (+) circuit for a short to voltage. Perform BODY VERIFICATION TEST VER-1. Body Verification Test
NO: Go To 3
3. CHECK FOR VOLTAGE ON THE (X299) AMPLIFIED LEFT I/P SPEAKER (-) CIRCUIT
Measure for voltage on the (X299) Amplified Left I/P Speaker (-) circuit.
Q: Is the voltage above 10.0 volts?
YES: Repair the (X299) Amplified Left I/P Speaker (-) circuit for a short to voltage. Perform BODY VERIFICATION TEST VER-1. Body Verification Test
NO: Replace the Amplifier. Perform BODY VERIFICATION TEST VER-1. Body Verification Test
