TECHNICAL DESCRIPTION (COMMENT)
The cause is probably a faulty radio and tape or CD player power supply circuit system.TROUBLESHOOTING HINTS
- Damaged wiring harness or connector.
- Malfunction of the radio and tape or CD player.
DIAGNOSIS PROCEDURE
STEP 1. Check to see that the power turns ON when the power switch is turned ON.
- Turn the ignition switch to "ACC" position.
- Turn ON the radio and tape or CD player power switch.
Q: Is it possible to put the radio and tape or CD player power in the "ON" position?
YES:
Go to Step 2.
NO: Go to Step 5.
STEP 3. Check the wiring harness between radio and tape or CD player connector C-102 (terminal 11) and battery.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-116 and joint connector (3) C-02, and repair if necessary.
Q: Are the wiring harnesses between radio and tape or CD player connector C-102 (terminal 11) and battery in good condition?
YES:
Go to Step 4.NO: Repair or replace the damage component(s). If the power switch is turned on, the radio and tape or CD player should operate normally.
STEP 4. Check the assembling state of the radio and tape or CD player.
NOTE: The radio and tape or CD player is earthed to the instrument panel centre reinforcement directly.
Q: Is the radio and tape or CD player installed correctly?
YES:
Repair or replace the radio and tape or CD player. If the power switch is turned on, the radio and tape or CD player should operate normally.NO: Install properly. If the power switch is turned on, the radio and tape or CD player should operate normally.
STEP 5. Measure the voltage at radio and tape or CD player connector C-102 in order to check the battery circuit of power supply system to the radio and tape or CD player (ignition switch ACC).
- Disconnect radio and tape or CD player connector C-102, and measure at the wiring harness side.
- Turn the ignition switch to "ACC" position.
- Measure the voltage between terminal 10 and earth.
OK: Battery positive voltage
Q: Is the check result normal?
YES:
Go to Step 8.NO: Go to Step 6.
STEP 7. Check the wiring harness between radio and tape or CD player connector C-102 (terminal 10) and ignition switch (ACC).
NOTE: L.H. drive vehicles;
prior to the wiring harness inspection, check intermediate connector C-116, and repair if necessary.
NOTE: R.H. drive vehicles;
prior to the wiring harness inspection, check junction block connector C-202 and intermadiate connector C-116, and repair if necessary.
Q: Is the wiring harness between radio and tape or CD player connector C-102 (terminal 10) and ignition switch (ACC) in good condition?
YES:
There is no action to be taken.NO: Repair or replace the damage component(s). If the power switch is turned on, the radio and tape or CD player should operate normally.
STEP 8. Check the assembling state of the radio and tape or CD player.
NOTE: The radio and tape or CD player is earthed to the instrument panel centre reinforcement directly.
Q: Is the radio and tape or CD player installed correctly?
YES:
Repair or replace the radio and tape or CD player. If the power switch is turned on, the radio and tape or CD player should operate normally.NO: Install properly. If the power switch is turned on, the radio and tape or CD player should operate normally.
