NOTE: The fault condition must be present to continue diagnosis. Use the
DRBIII
t to perform the Amplifier pretest to verify the fault condition is
present before continuing diagnosis.
NOTE: Amplifier speaker circuits are both shorted simultaneously.
Turn the ignition off.
Access and disconnect the Right Front Door and Left Rear Speaker harness
connectors.
Turn the ignition on.
With the DRBIII
t, perform the Amplifier pretest.
Is the fault condition still present?
All
Yes
→ Go To 2
No
→ Replace the Right Front Door and Left Rear Speakers in accor-
dance with the Service Information.
Perform BODY VERIFICATION TEST - VER 1.

Measure the resistance of the Right Front Door Speaker (+) and (-) circuits.
Measure the resistance of the Left Rear Speaker (+) and (-) circuits.
Is the resistance below 5.0 ohms on each measurement?
All
Yes
→ Repair both Speaker (+) and (-) circuits for a short together.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Replace the Amplifier in accordance with the Service Information.
