2. Measure the resistance between the speakers and the stereo component amplifier assembly to check for an open circuit in the wire harness.
  Standard resistance: Below 1 Ω
3. Measure the resistance between the speakers and body ground to check for a short circuit in the wire harness.
  Standard resistance: 10 kΩ or higher
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

Resistance check.

Measure the resistance according to the value(s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester connection	Condition	Specified condition
1 - 2	Always	0.81 to 1.61 Ω
3 - 4	Always	0.81 to 1.61 Ω

NOTE: The speaker should not be removed for checking.

NG: REPLACE NO. 1 WOOFER BOX SPEAKER ASSEMBLY

OK: Go to next step

INSPECT FRONT NO.1 SPEAKER ASSEMBLY
1. Resistance check.
  1. Measure the resistance between the terminals of the speaker.
    NOTE: The speaker should not be removed for checking.
    
    Standard resistance: Coupe: 3 to 4 Ω
    
    Convertible: 4 to 6 Ω
NG: REPLACE FRONT NO.1 SPEAKER ASSEMBLY

OK: Go to next step
INSPECT FRONT NO.2 SPEAKER ASSEMBLY
1. Check that malfunction disappears when another speaker in good condition is installed.
  OK: Malfunction disappears.
  
  HINT:
  - Connect all the connectors to the speakers.
  - When there is a possibility that either right or left front speaker is defective, inspect by interchanging the right one and the left one.
OK: REPLACE FRONT NO.2 SPEAKER ASSEMBLY

NG: Go to next step
INSPECT REAR SPEAKER ASSEMBLY
1. Resistance check.
  1. Measure the resistance between the terminals of the speaker.
    NOTE: The speaker should not be removed for checking.
    
    Standard resistance: Coupe: 1.75 to 2.75 Ω
    
    Convertible: Approximately 2.4 Ω
NG: REPLACE REAR SPEAKER ASSEMBLY

OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
