•  Battery malfunction
•  Generator malfunction
•  Instrument cluster connector or terminal malfunction
•  Active driving display connector or terminal malfunction
•  Active driving display power supply circuit malfunction
―  Short to ground in wiring harness between active driving display terminal I and instrument cluster terminal 2O
―  Open circuit in wiring harness between active driving display terminal I and instrument cluster terminal 2O
•  Active driving display malfunction

Diagnostic Procedure

Step

Inspection

Action

1
VERIFY PCM DTCs
•  Are any DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
No
Go to the next step.
2
VERIFY INSTRUMENT CLUSTER DTCs
•  Retrieve the instrument cluster DTCs using the M-MDS.
•  Are any DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
No
Go to the next step.
3
INSPECT BATTERY
•  Is the battery normal?
Yes
Go to the next step.
No
Recharge or replace the battery, then go to Step 8.
4
INSPECT GENERATOR
•  Is the generator normal?
Yes
Go to the next step.
No
Replace the generator, then go to Step 8.
5
INSPECT INSTRUMENT CLUSTER CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the instrument cluster connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 8.
6
INSPECT ACTIVE DRIVING DISPLAY CONNECTOR CONDITION
•  Disconnect the active driving display connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 8.
7
VERIFY INSTRUMENT CLUSTER POWER SUPPLY VOLTAGE
•  Always reconnect all disconnected connectors.
•  Display the PID VPWR_B using the M-MDS.
•  Is the voltage B+?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between active driving display terminal I and instrument cluster terminal 2O.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to the next step.
8
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC for the active driving display using the M-MDS.
•  Retrieve the active driving display DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the active driving display.
Go to the next step.
No
Go to the next step.
9
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
