INSPECT FRONT NO. 1 SPEAKER

(a) Resistance check.

(1) Measure the resistance between the terminals of the speaker. Standard resistance: 1.8 to 2.6 Q

REPLACE FRONT NO. 1 SPEAKER

INSPECT FRONT NO. 2 SPEAKER

(a) Check that the malfunction disappears when another speaker in good condition is installed.

Malfunction disappears.

HINT:

• Connect all the connectors to the front No. 2 speakers.

• When there is a possibility that either the right or left front speaker is defective, inspect by interchanging the right one with the left one.

• Perform the above inspection on both LH and RH sides.

REPLACE FRONT NO. 2 SPEAKER

INSPECT REAR SPEAKER
