NOTE: NOTE: The fault condition must be present to continue
diagnosis. Use the DRBIII

T

to perform the Amplifier pretest to ver-

ify the fault condition is present before continuing diagnosis.

NOTE: NOTE: Amplifier speaker circuits are both shorted simul-
taneously.
Turn the ignition off.

ness connectors.

Turn the ignition on.

With the DRBIII

T

, perform the Amplifier pretest.

Is the fault condition still present?

Yes

>> Go To 2

No

>> Replace the Right Front I/P and Left Rear Speakers in
