Checking the Front Right Loudspeaker and Leads

Checking The Front Right Loudspeaker And Leads







- Turn the ignition switch to the OFF position.
- Remove the key from the ignition.







Unplug the connector:
- Amplifier (354)












Take a resistance reading between

- 18 - Amplifier
- 37 - Amplifier

The reading should be 3 Ohm - 6 Ohm

Checking the wiring harness.
Jiggle the leads and in-line connectors at several places and in different directions to reveal intermittent breaks and short circuits in the wiring harness. Observe the multimeter, test lamp or diagnostic tool while doing this.

Is the function correct?

NO - Rectifying the Lead - I

YES - Continue with Checking The Front Right Loudspeaker And Leads.

















Measure the resistance. The value should be infinite.

- 18 - Amplifier
- B-
