STEP 2. Using scan tool MB991958, read the combination
meter diagnostic trouble code.
Check if DTC is set to the combination meter.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.

position.

(5) Check if diagnostic trouble code is set.
Q: Is the DTC set?

YES : Replace the combination meter, and then go to Step

3.

NO : The procedure is complete.

STEP 3. Recheck for diagnostic trouble code.
Check if DTC is set to the combination meter.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON"

position.

(3) Check if diagnostic trouble code is set.
Q: Is the DTC set?

DTC B2464: The sticking of multi information meter switch

CAUTION

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

.

TROUBLE JUDGMENT

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

.

TROUBLESHOOTING HINTS

• The multi information meter switch may be defec-

tive

• The combination meter may be defective

• The wiring harness or connectors may have

loose, corroded, or damaged terminals, or termi-
nals 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.)

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 multi information meter switch.
Check the multi information meter switch (Refer to

P.54A-92

).

Q: Is the check result normal?

YES : Go to Step 3.
NO : Replace the multi information meter 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 ohm 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.
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.

DTC B2465: Ignition switch signal error

.

TROUBLE JUDGEMENT

If 5 seconds or more elapses with the ignition switch
state and the data from the CAN communication con-
tradicted, the combination meter stores the DTC
B2465.

.

TROUBLESHOOTING HINTS
