STEP 1. Checking with audio speaker test.
STEP 2. Check the speaker or tweeter.
(1) Remove the speaker or tweeter.
(2) Check that the speaker or tweeter outputs the noise when the voltage of 5 volts is applied to the speaker or tweeter connector terminal.
Do the speaker output the noise?
: Go to Step 5. : Go to Step 3. Replace the speaker or tweeter.
STEP 3. Check the wiring harness between the emergency call relay box connector terminal and the multivision display connector terminal.
STEP 4. Check the wiring harness between the front door speaker (RH) connector terminal and the emergency call relay box connector terminal.
STEP 5. Check the wiring harness between the speaker or tweeter connector terminal and the multivision display connector terminal.
Front door speaker (LH)
- Check of short circuit in FL+, FL- line between front door speaker (LH) connector and multivision display connector.
Front door speaker (RH) <Vehicles without MITSUBISHI CONNECT Safeguard Services and Remote Services>
- Check of short circuit in FR+, FR- line between front door speaker (RH) connector and multivision display connector.
Front tweeter (LH)
- Check of short circuit in FL+, FL- line between front door speaker (LH) connector and multivision display connector.
Front tweeter (RH)
- Check of short circuit in FR+, FR- line between front door speaker (RH) connector and multivision display connector.
Rear door speaker (LH)
- Check of short circuit in RL+, RL- line between front door speaker (LH) connector and multivision display connector.
Rear door speaker (RH)
- Check of short circuit in RR+, RR- line between front door speaker (RH) connector and multivision display connector.
Is the check result normal?
Go to Step 10. Repair the connector(s) or wiring harness. (Replace the harness assembly because the aluminum harness cannot be repaired.)
STEP 6. Check the speaker or tweeter.
Follow the speaker test to check which speaker or tweeter does not sound.(1) Remove the speaker or tweeter.
(2) Check that the speaker or tweeter outputs the noise when the voltage of 5 volts is applied to the speaker or tweeter connector terminal.
Do the speaker output the noise?
: Go to Step 9. : Go to Step 7. Replace the speaker or tweeter.
STEP 7. Check the wiring harness between the emergency call relay box connector terminal and the multivision display connector terminal.
STEP 8. Check the wiring harness between the front door speaker (RH) connector terminal and the emergency call relay box connector terminal.
STEP 9. Check the wiring harness between the speaker or tweeter connector terminal and the multivision display connector terminal.
Follow the speaker test to check which speaker or tweeter circuit is defective.Front door speaker (LH)
