Inspection Procedure 10: The multi-information display screen cannot be changed with the operation of the meter information switch.
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 the meter information switch is received, the combination meter switches the multi-information display screen. If the multi-information display screen does not switch normally, the meter information switch, wiring harness, connector(s), or combination meter may have a problem.
 
 
TROUBLESHOOTING HINTS
  • The meter information switch may be defective <High contrast meter>
  • The combination meter may be defective
  • The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector <High contrast meter>
 
 
DIAGNOSIS
Required Special Tools:
  • MB991223: Harness Set
  • MB992006: Extra Fine Probe
STEP 1. Using scan tool (M.U.T.-III), read the combination meter diagnostic trouble code.
Check if DTC No. B2463 <Standard meter> or No. B2464 <High contrast meter> is set.
(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) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(4) Check if DTC is set.
Is DTC No. B2463 <Standard meter> or No. B2464 <High contrast meter> set?
Follow the relevant DTC procedure (Refer to ).
: Go to Step 5.
: Go to Step 2.
 
STEP 2. Meter information switch check.
Check the meter information switch. Refer to .
Is the check result normal?
Go to Step 3.
Replace the meter information switch.
 
STEP 3. Resistance measurement at the meter information switch connector
(1) Disconnect the meter information switch connector, the measure at the harness side.
(2) Measure the resistance between the meter information switch connector (ground terminal) and ground.
OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. Check of short to power supply and open circuit in MODE line between combination meter connector and meter information switch connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. Check by scan tool (M.U.T.-III) "Special Function"
  • Item 2: LCD (AUTO) (Refer to ).
Is the check result normal?
Go to Step 6.
Replace the combination meter.
 
STEP 6. Retest the system.
Check that the multi-information display screen works normally.
Is the check result normal?
The procedure is complete.
