DTC B2464: The Sticking Of Meter Information Switch

CAUTION: Whenever the ECU is replaced, ensure that the communication circuit is normal.

Meter Information Switch Circuit:

TROUBLE JUDGMENT
If the combination meter detects the meter information switch pressed state for 60 seconds or more continuously, DTC B2464 is stored.

TROUBLESHOOTING HINTS
- The meter information switch may be defective
- 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

DIAGNOSIS

Required Special Tools:
- MB991223: Harness Set
- MB992006: Extra Fine Probe
- MB991958: Scan Tool (M.U.T.-III Sub Assembly)
- MB991824: Vehicles Communication Interface (V.C.I.)
- MB991827: M.U.T.-III USB Cable
- MB991910: M.U.T.-III Main Harness A (Vehicles with CAN communication system)

STEP 1. Check meter information switch connector C-02 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is meter information switch connector C-02 in good condition?

YES : Go to Step 2.

NO : Repair the connector.

STEP 2. Check the meter information switch.

Check the meter information switch. Meter Information Switch Check

Q: Is the check result normal?

YES : Go to Step 3.

NO : Replace the meter information switch.

STEP 3. Measure at meter information switch connector C-02 in order to the ground circuit to the meter information switch.

1. Disconnect meter information switch connector C-02, and measure at the wiring harness side.







2. Measure the resistance value between terminal 4 and ground.
- The measured value should be 2 ohms or less.

Q: Does the measured resistance value correspond with this range?

YES : Go to Step 5.

NO : Go to Step 4.

STEP 4. Check the wiring harness between meter information switch connector C-02 (terminal 4) and ground.

- Check the ground wire for open circuit.

Q: Is the wiring harness between fuel meter information switch connector C-02 (terminal 4) and ground in good condition?

YES : Go to Step 7.

NO : Repair the wiring harness.

STEP 5. Check combination meter connector C-04 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is combination meter connector C-04 in good condition?

YES : Go to Step 6.

NO : Repair the connector.

STEP 6. Check the wiring harness between meter information switch connector C-02 (terminal 1) and combination meter connector C-04 (terminal 3).

- Check the communication line for open circuit and short circuit.

Q: Are the wiring harness between meter information switch connector C-02 (terminal 1) and combination meter connector C-04 (terminal 3) in good condition?

YES : Go to Step 7.

NO : Repair the wiring harness.

STEP 7. Recheck for diagnostic trouble code.

Check again if the DTC is set to the combination meter.

1. Connect scan tool MB991958. Refer to "How to connect the Scan Tool (M.U.T.-III)." How to Connect the Scan Tool (M.U.T.-III)
2. Turn the ignition switch to the "ON" position.
3. Erase the DTC.
4. Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
5. Check if DTC is set.

Q: Is the DTC set?

YES : Go to Step 1.

NO : The procedure is complete.
