TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the Amplifier C1 harness connector.
Disconnect the Radio harness connector.
Measure the resistance of each left rear speaker (+) and (-) circuit between the Radio
and the Amplifier.
Is the resistance below 5.0 ohms for each circuit?
All
Yes → Go To 4
No → Repair the speaker circuits for an open.
Perform BODY VERIFICATION TEST - VER 1.
4 Turn the ignition off.
Reconnect the Radio harness connector.
Disconnect the Amplifier C1 harness connector.
Turn the ignition on and the Radio on to a known good radio station or have a tape
or CD playing.
Turn the radio volume control up at least 25 positions.
With the voltmeter in the AC voltage scale, measure the voltage of each left rear
speaker circuit at the Amplifier C1 connector.
NOTE: Perform this test on each left rear speaker circuit.
Is the voltage at least 120mV AC (0.12 VAC) on each speaker circuit?
All
Yes → ReplacetheAmplifier in accordance withthe Service Information.
Perform BODY VERIFICATION TEST - VER 1.
