54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > RADIO AND CD PLAYER > SYMPTOM PROCEDURES > AUDIO ILLUMINATION DOES NOT WORK NORMALLY.
Inspection Procedure 4: Audio illumination does not work normally.
 
 
cautionBefore replacing the radio and CD player, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
COMMENTS ON TROUBLE SYMPTOM
If the tail lamps illuminate, illumination signal is sent from the A/C controller assembly to the radio and CD player. This switches the illumination of the radio and CD player from day mode to night mode. If the mode is switched, the illumination signal line, the A/C controller assembly or the radio and CD player may be defective.
 
 
 
PROBABLE CAUSES
  • Malfunction of radio and CD player
  • Malfunction of A/C controller assembly
  • Damaged harness wires and connectors
 
 
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check that the tail lamps illuminate.
Is the check result normal?
Go to Step 2.
Diagnose the tail lamps (Refer to ).
 
STEP 2. Voltage measurement at radio and CD player connector (ILL+ terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Turn the taillamp switch to ON position.
(3) Check the voltage between the radio and CD player connector (ILL+ terminal) and body earth.
OK: System voltage
Is the check result normal?
Replace the radio and CD player.
Go to Step 3.
 
STEP 3. Check of short to power supply, short to earth, and open circuit in ILL+ line between radio and CD player connector and A/C controller assembly connector.
Is the check result normal?
Replace the A/C controller assembly.
Repair the connector(s) or wiring harness.
