Inspection Procedure 9: The combination meter light does not illuminate normally or the multi-information display is not displayed normally.
 
 
cautionBefore replacing the combination meter, be sure to check that the power supply circuit, ground circuit, and communication circuit are normal.
 
 
 
 
 
TECHNICAL DESCRIPTION (COMMENT)
When the signal from each ECU is received via the CAN communication, the combination meter illuminates the corresponding display light or warning light, or has the multi-information display to display corresponding information.
If the lights do not illuminate or the multi-information display does not display normally, the wiring harness and connector(s) in the CAN bus lines, or the each ECU or the combination meter may have a problem.
 
 
 
TROUBLESHOOTING HINTS
  • The combination meter may be defective.
  • The each ECU may be defective.
 
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-III), diagnose the CAN bus line.
(1)
cautionTo prevent damage to scan tool (M.U.T.-III), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-III).
Connect scan tool (M.U.T.-III). Refer to "How to connect the Scan Tool (M.U.T.-III) ."
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the CAN bus line found to be normal?
Go to Step 2.
Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. Using scan tool (M.U.T.-III), read the combination meter diagnostic trouble code.
Check again if the DTC is set in the combination meter.
Is the DTC set?
Troubleshoot the combination meter (Refer to ).
Go to Step 3.
 
STEP 3. Using scan tool (M.U.T.-III), read for any diagnostic trouble code.
Check again if the DTC is set in the engine control module, TCM, ASC-ECU, EPS-ECU, KOS&OSS-ECU, SRS-ECU, ETACS-ECU and A/C-ECU.
Is the DTC set in the any of the above?
Set to the engine control module. : Troubleshoot the MFI system. GROUP 13A - DTC Chart .
Set to the TCM. : Troubleshoot the CVT. Refer to GROUP 23A - DTC Chart .
Set to the ASC-ECU. : Troubleshoot the ASC. Refer to GROUP 35C - Troubleshooting .
Set to the EPS-ECU. : Troubleshoot the EPS. Refer to GROUP 37 - Troubleshooting .
Set to the KOS&OSS-ECU. : Troubleshoot the KOS. Refer to GROUP 42B - Troubleshooting .
Set to the SRS-ECU. : Troubleshoot the SRS. Refer to GROUP 52B - Troubleshooting .
Set to the ETACS-ECU. : Troubleshoot the ETACS-ECU. Refer to .
Set to the A/C-ECU. : Troubleshoot the A/C. Refer to GROUP 55B - Troubleshooting .
The DTC is not set. : Go to Step 4.
 
STEP 4. Check by scan tool (M.U.T.-III) "Special Function."
Using scan tool (M.U.T.-III), select "Test" from the special function of the combination meter. Execute the following item to check the liquid crystal display.
  • Item 2: LCD (AUTO)
  • Item 5: Illumination (AUTO)
  • Item 6: Indicator (AUTO)
Is the check result normal?
Go to Step 5.
Replace the combination meter, and then go to Step 5.
 
STEP 5. Retest the system.
Check that display lights or warning lights are illuminated normally, or multi-information display is displayed normally.
Is the check result normal?
The procedure is complete (If no malfunctions are found in all steps, an intermittent malfunction is suspected. Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
