TROUBLE DIAGNOSIS

Display Control Unit Branch Line CircuitBKS002ET
INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the display control unit for damage, bend and loose connection
(unit side and connector side).
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of display control unit.
2. Check the resistance between the display control unit harness connector terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair the display control unit branch line.
3. CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply, ignition signal and the ground circuit of the display control unit. Refer to AV- 6 4 ,
"Schematic — INF/D —" .
OK or NG
OK >>
Present error: Replace the display control unit. Refer to AV- 11 2 , "Removal and Installation of
Display Control Unit" .

Past error: Error was detected in the display control unit branch line.
NG >> Repair the power supply and the ground circuit.
