54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > COMBINATION METER > SYMPTOM PROCEDURES > POWER SUPPLY CIRCUIT
Inspection Procedure 1: Power supply circuit check
Inspection Procedure 2: The odometer and the trip meter are not displayed.
Inspection Procedure 3: No needle meters work.
Inspection Procedure 4: If the ignition switch is turned to the ON position, the indicator and warning lamps do not illuminate normally.
 
 
 
 
COMMENTS ON TROUBLE SYMPTOM
If the odometer and trip meter is not displayed, odometer and trip meter indicates "-------", or no needle meters work, power supply to the combination meter, or the combination meter itself may have a problem.
 
 
PROBABLE CAUSES
  • Damaged harness wires and connectors
  • Malfunction of combination meter
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
Check if diagnosis code is set in the combination meter.
Is the diagnosis code set?
Troubleshoot the combination meter. Refer to .
Go to Step 2.
 
STEP 2. Voltage measurement at the combination meter connector
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the voltage between the combination meter connector (B+B terminal) and the body earth.
OK: System voltage
Is the check result normal?
Go to Step 4.
Go to Step 3.
 
STEP 3. Check of short to power supply circuit in B+B line between the fusible link and combination meter connector.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
Repair the connector(s) or wiring harness.
 
STEP 4. Voltage measurement at the combination meter connector
(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 combination meter connector (IG1 terminal) and the body earth.
OK: System voltage
Is the check result normal?
Go to Step 7.
Go to Step 5.
 
STEP 5. M.U.T.-IIISE other system service data
Check the input signal from the ignition switch (IG1) in the ETACS-ECU.
  • Turn the ignition switch to the ON position.
 
Item No.Item nameNormal condition
79IG voltageSystem voltage
OK: Normal condition is displayed.
Is the check result normal?
Go to Step 6.
NO : Troubleshoot the ETACS-ECU. Refer to Inspection Procedure 2 "The ignition switch (IG1) signal is not received." .
 
STEP 6. Check of short to power supply circuit in IG1 line between the ignition switch (IG1) and combination meter connector.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Repair the connector(s) or wiring harness.
 
STEP 7. Resistance measurement at the combination meter connector
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the combination meter connector (GND terminal) and the body earth.
OK: Continuity exists (2 Ω or less)
Is the check result normal?
Go to Step 9.
Go to Step 8.
 
STEP 8. Check of short to earth circuit in GND line between combination meter connector and body earth.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Repair the connector(s) or wiring harness.
 
STEP 9. Retest the system
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Replace the combination meter.
