Right Front I/P and Right Front Door Channels Shorted Across

RIGHT FRONT I/P AND RIGHT FRONT DOOR CHANNELS SHORT ACROSS

WHEN MONITORED
When the DRBIII(R) performs the Speaker Output test.

SET CONDITION
When the Right Front I/P Speaker and Right Front Door Speaker circuits are simultaneously shorted.

POSSIBLE CAUSES
- Right front I/P and right front door channels shorted across
- Right front I/P speaker and right front door speaker
- Right front I/P and right front door speaker circuits shorted
- Amplifier

1. RIGHT FRONT I/P AND RIGHT FRONT DOOR CHANNELS SHORTED ACROSS





NOTE:
- The fault condition must be present to continue diagnosis. Use the DRBIII(R) to perform the Amplifier pretest to verify the fault condition is present before continuing diagnosis.
- Amplifier speaker circuits are both shorted simultaneously.

Turn the ignition off.
Access and disconnect the Right Front I/P and Right Front Door Speaker harness connectors.
Turn the ignition on.
With the DRBIII(R), perform the Amplifier pretest.

Q: Is the fault condition still present?

YES: Go To 2
NO: Replace the Right Front I/P and Right Front Door Speakers Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. RIGHT FRONT I/P AND RIGHT FRONT DOOR SPEAKER CIRCUITS SHORTED




Turn the ignition off.
Access and disconnect the Right Front I/P Speaker harness connector.
Access and disconnect the Right Front Door Speaker harness connector.
Access and disconnect the Amplifier C2 harness connector.
Measure the resistance of the Right Front I/P Speaker (+) and (-) circuits.
Measure the resistance of the Right Front Door Speaker (+) and (-) circuits.

Q: Is the resistance below 5.0 ohms on each measurement?

YES: Repair both Speaker (+) and (-) circuits for a short together. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the Amplifier. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
