Malfunction warning light illuminates

POSSIBLE CAUSE
•  PCM malfunction
•  Instrument cluster malfunction
•  Connector or pin malfunction
•  Short circuit in wiring harness between CAN-L, CAN-H and ground
•  Open circuit in CAN wiring harness (CAN-L, CAN-H)
•  CAN wiring harness (CAN-L, CAN-H) short each other
•  Malfunction in brake switch signal input to PCM (PCM stores DTC P0571:00 and/or P0703:00.)

Diagnostic procedure

STEP

INSPECTION

RESULT

ACTION

1
•  Start the engine.
•  Does the malfunction warning light turn off?
Yes
Troubleshooting completed. (The system is normal.)
No
Go to the next step.
2
•  Is the DTC P0571:00 and/or P0703:00 present?
Yes
Go to applicable DTC inspection.
No
Go to the next step.
3
•  Start the engine.
•  Verify that the warning and indicator lights condition.
•  Do two or more lights illuminate at the same time?
Yes
Go to the Step 5.
No
Go to the next step.
4
•  Turn off the malfunction warning light using M-MDS instrument cluster active command modes WL+IL.
•  Does the malfunction warning light turn off according to active command modes?
Yes
Inspect the connector condition of the following parts:
―  Instrument cluster
―  PCM
If connector connection is poor:
•  Connect the connector of each part securely.
If malfunction occurs on part side:
•  Replace each part.
If malfunction occurs on vehicle wiring harness side:
•  Repair or replace the pins or connector.
No
Replace the instrument cluster.
5
•  Retrieve DTC from the instrument cluster using the M-MDS.
•  Is the DTC detected?
Yes
Go to the applicable DTC troubleshooting procedure.
No
Go to the next step.
6
•  Measure the resistance between the DLC-2 terminals F and E.
•  Is the resistance below 60 ohms?
Yes
Go to the next step.
No
Go to Step 9.
7
•  Inspect the DLC-2 terminals F and E for short to power supply or ground.
•  Is there any malfunction?
Yes
Inspect the wiring harness and CAN system-related module.
Repair or replace the malfunctioning part.
No
Replace the instrument cluster.
8
•  Switch the ignition to off.
•  Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminal.
9
•  Measure the resistance between the instrument cluster connector terminals 2B and 2D.
•  Is the resistance 114—126 ohms?
Yes
Inspect the wiring harness and CAN system-related module.
Repair or replace the malfunctioning part.
No
Replace the instrument cluster.
