Code No.B1201: Fuel information problem
 
 
cautionBefore replacing the combination meter, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
 
 
TROUBLE JUDGEMENT
With the ignition switch at the ON position and diagnosis code No. U1190 is not set, if the combination meter detects the abnormal resistance of fuel level sensor circuit for 64 seconds continuously, diagnosis code No. B1201 is set.
 
 
PROBABLE CAUSES
  • Damaged harness wires and connectors
  • Malfunction of fuel pump and gauge unit (main)
  • Malfunction of fuel gauge unit (sub) <4WD>
  • Malfunction of combination meter
 
 
DIAGNOSIS PROCEDURE
STEP 1. Voltage measurement at the fuel pump and gauge unit (main) circuit
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between the fuel pump and gauge unit (main) connector terminals No.1 and No.2.
OK: Approximately 12V
Is the check result normal?
Check the fuel pump and gauge unit (main) (Refer to ).
Go to Step 2.
 
STEP 2. Fuel gauge unit (sub) check
Check the fuel gauge unit (sub) (Refer to ).
Is the check result normal?
Go to Step 3.
Replace the fuel gauge unit (sub).
 
STEP 3. Resistance measurement at the fuel pump and gauge unit (main) connector
(1) Disconnect the fuel pump and gauge unit (main) connector, the measure at the harness side.
(2) Measure the resistance between the fuel pump and gauge unit (main) connector (earth terminal) and the body earth.
OK: Continuity exists (2 Ω or less)
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. Check of open or short to earth circuit in F/G line between combination meter connector and fuel gauge unit (sub) connector, between fuel gauge unit (sub) connector and fuel pump and gauge unit connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. M.U.T.-IIISE actuator test
  • Item No.03: Fuel gauge: 0 →100%
OK: The fuel gauge operates.
Is the check result normal?
Go to Step 6.
Replace the combination meter.
 
STEP 6. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the combination meter.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to the ON position.
(3) Check if diagnosis code is set.
Is the diagnosis code set?
Replace the combination meter.
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
