DIAGNOSIS CODE CHART

M1540200600535

CAUTION

• During diagnosis, a diagnosis code associated with other system may be set when the ignition 

switch is turned on with connector(s) disconnected. On completion, confirm all systems for diag-
nosis code(s). If diagnosis code(s) are set, erase them all.

• If the combination meter needs to be replaced as a result of troubleshooting, the current driving 

distance and elapsed days must be entered into the meter after the replacement in order to be 
used for service reminder function. Therefore, read "Integrated mileage for reminder," "Integrated 
days for reminder," "Mileage until Extra reminder," "Months until Extra reminder," and "Current 
schedule" from the meter before the replacement using the special function of M.U.T.-III, and note 
them. For the operation method of M.U.T.-III, refer to . If "Integrated mileage for reminder" or "Inte-
grated days for reminder" cannot be read from the meter using M.U.T.-III, use the following 
method.

a. As for the driving distance for check warning, use the driving distance displayed on the multi 

information display.

b. As for the elapsed days for check warning, calculate the number of elapsed days from the 

delivery date to the customer (service reminder function start date) and current date.

DIAGNOSIS CODE PROCEDURES

Code No.B1200 Malfunction of odometer

TROUBLE JUDGMENT
If the odometer information, which is stored in the 
combination meter, is abnormal with the ignition 
switch at the ON position and the system voltage at 
10 

−16 V (data from ETACS-ECU), the diagnosis 

code No. B1200 is stored.

PROBABLE CAUSES
Malfunction of combination meter

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code
Check if diagnosis code is set to the combination 
meter.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) 

position to "ON" position.

(3) Check if diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Replace the combination meter, and then 

go to Step 2.

NO : 

The trouble can be an intermittent 
malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/Inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ). 

STEP 2. Check whether the diagnosis code is 
reset.
Check if diagnosis code is set to the combination 
meter.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) 

position to "ON" position.

(3) Check if diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Go to Step 1.

NO : 

The diagnosis is complete.

Code No.B1201: Fuel information error

CAUTION

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

TROUBLE JUDGEMENT
With the ignition switch at the ON position and the 
system voltage at 10 

−16 V (data from ETACS-ECU), 

if the combination meter detects the abnormal resist-
ance of fuel level sensor circuit for 64 seconds con-
tinuously, the diagnosis code No. B1201 is stored.

PROBABLE CAUSES

• Damaged harness wires and connectors

• Malfunction of fuel pump and gauge assembly

• Malfunction of combination meter

DIAGNOSIS PROCEDURE

STEP 1. Connector check: D-19 fuel pump and 
gauge unit connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the connector, and then go to Step 9.

STEP 2. Check of fuel pump and gauge unit 
circuit
(1) Disconnect the D-19 fuel pump and gauge unit 

connector.

(2) Use the special tool Check harness (MB991219) 

to connect a test lamp (12 V - 3.4 W) between the 
wiring harness connector terminals 1 and 2.

(3) Turn the ignition switch to the ON position.
(4) Check if the test lamp illuminates.

OK: Illuminates

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Go to Step 3.

STEP 3. Fuel pump and gauge unit and fuel 
gauge unit check

Go to Step 4.

NO : 

Replace the fuel pump and gauge unit and 
fuel gauge unit.

STEP 4. Resistance measurement at the D-19 fuel 
pump and gauge unit connector
(1) Disconnect the fuel pump and gauge unit 

connector, the measure at the harness side.

(2) Measure the resistance between the D-19 fuel 

pump and gauge unit connector terminal No. 1 
and the body earth.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 5.

STEP 5. Check the wiring harness between the D-
19 fuel pump and gauge unit connector terminal 
No. 1 and the body earth.
Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 9.

NO : 

Repair the wiring harness, and then go to 
Step 9.

STEP 6. Connector check: C-01 combination 
meter connector

Q: Is the check result normal?

STEP 7. Check the wiring harness between the C-
01 combination meter connector terminal No. 18 
and the D-19 fuel pump and gauge unit connector 
terminal No. 2
Check the output lines for open circuit.
NOTE: Before the wiring harness check, check the 
intermediate connectors C-16 and D-09, and repair 
them if necessary.
