Inspection Procedure

WARNING: This page is about a different car, the 2006 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.

CHECK HARNESS AND CONNECTOR
1. Disconnect the connectors shown in the illustration on the left from the stereo component amplifier assembly or the radio receiver assembly and speakers.

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

OK: GO TO NEXT STEP

NG: REPLACE WOOFER BOX SPEAKER ASSEMBLY NO.1

OK: GO TO NEXT STEP

INSPECT FRONT NO.1 SPEAKER ASSEMBLY
1. Resistance check.
  1. Measure the resistance between the terminals of the speaker.
    Resistance:
    
    Separate Type Amplifier (Coupe): 3 to 4 Ω
    
    Separate Type Amplifier (Convertible): 3.5 to 4.5 Ω
    
    Built-in Type Amplifier: Approximately 4 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 detective, inspect by interchanging the right one and the left one.
NG: REPLACE FRONT NO.2 SPEAKER ASSEMBLY

OK: GO TO NEXT STEP
INSPECT REAR SPEAKER ASSEMBLY
1. Resistance check.
  1. Measure the resistance between the terminals of the speaker.
    Resistance:
    
    Separate Type Amplifier (Coupe): 1.75 to 2.75 Ω
    
    Separate Type Amplifier (Convertible): Approximately 2.4 Ω
    
    Built-in Type Amplifier: 5.1 to 6.9 Ω
NG: REPLACE REAR SPEAKER ASSEMBLY

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