54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > SMARTPHONE-LINK DISPLAY AUDIO (SDA) > SYMPTOM PROCEDURES > WHEN POWER SWITCH IS TURNED "ON," NO POWER IS AVAILABLE<VEHICLES WITHOUT AUTO STOP & GO (AS&G) SYSTEM>
Inspection Procedure 1: Power of the multivision display does not turn ON when the ignition switch is in the "ACC" position or "ON" position. <Vehicles without Auto Stop & Go (AS&G) System>
 
 
cautionBefore replacing the multivision display, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
OPERATION
When the ignition switch is in the ON or ACC position, the multivision display power can be turned ON. With the multivision display power ON, when the ignition switch is turned to the "LOCK" (OFF) position, the power for multivision display is also turned OFF.
 
 
COMMENTS ON TROUBLE SYMPTOM
Provided that the audio diagnosis code is not set, if the power for multivision display cannot be turned ON, the multivision display, or power supply circuit for multivision display may have a problem.
 
 
PROBABLE CAUSES
  • Malfunctions of multivision display
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III other system data list.
Check the ETACS-ECU input signal of ACC relay.
  • Turn the ignition switch to the "ACC" position.
 
Item No.Item nameNormal condition
Item 288ACC switchON
OK: Normal condition is displayed.
Is the check result normal?
Go to Step 2.
Refer to ETACS - Input Signal Procedure 1 "The ignition switch (ACC) signal is not sent to the ETACS-ECU" .
 
STEP 2. Check of short to power supply, short to earth, and open circuit in ACC line between multivision display connector and ETACS-ECU connector.
Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.
 
STEP 3. Voltage measurement at multivision display connector (+B2 terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Check the voltage between the multivision display connector (+B2 terminal) and body earth.
OK: System voltage
Is the check result normal?
Go to Step 5.
Go to Step 4.
 
STEP 4. Check of short to earth, and open circuit +B2 line between fusible link and multivision display connector.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
Repair the wiring harness.
 
STEP 5. Resistance measurement at multivision display connector (GND, GND2 terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Check the continuity between the multivision display connector (GND terminal) and body earth.
OK: Continuity exists (2 Ω or less)
(3) Check the continuity between the multivision display connector (GND2 terminal) and body earth.
OK: Continuity exists (2 Ω or less)
Is the check result normal?
Go to Step 7.
Go to Step 6.
 
STEP 6. Check of open circuit in GND or GND2 line between multivision display connector and body earth.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
Repair the wiring harness.
 
STEP 7. Retest the system.
Check if the multivision display power is turned ON.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction).
Replace the multivision display (Refer to ).
