Right Front Door and Right Rear Channels Shorted Across

RIGHT FRONT DOOR AND RIGHT REAR CHANNELS SHORT ACROSS

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

SET CONDITION
When the Right Front Door Speaker and Right Rear Speaker circuits are simultaneously shorted.

POSSIBLE CAUSES
- Right front door and right rear channels shorted across
- Right front door and right rear speaker circuits shorted
- Right front door speaker and right rear speaker
- Amplifier

1. RIGHT FRONT DOOR AND RIGHT REAR 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 Door and Right Rear 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 Door and Right Rear Speakers. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. RIGHT FRONT DOOR AND RIGHT REAR SPEAKER CIRCUITS SHORTED




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