METER / GAUGE SYSTEM Hybrid System Indicator Malfunction

DESCRIPTION

A hybrid system indicator is adopted for this vehicle. In this circuit, the meter CPU receives eco-zone indicator level signal from the power management control ECU via the CAN communication line. The meter CPU controls the operation of the hybrid system indicator according to the eco-zone indicator level signal received from the power management control ECU via the CAN communication line.

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

   
   

   1. Check if a CAN communication DTC is output.

      
      

      1. for LHD (See page ).

         Click here

      2. for RHD Click here.

         Result

         Result	Proceed to
         CAN communication DTC is not output (except Sport Package)	A
         CAN communication DTC is not output (for Sport Package)	B
         CAN communication DTC is output (for LHD)	C
         CAN communication DTC is output (for RHD)	D

2. PERFORM ACTIVE TEST USING GTS (HV SYSTEM INDICATOR)

   
   

   1. Use the Active Test to check the operation of the hybrid system indicator Click here.

      Combination Meter

      Tester Display	Test Part	Control Range	Diagnostic Note
      HV System Indicator	Hybrid system Indicator	MIN, -50, 0, 100, 200, 300, 400 or MAX (%)	-

      OK
      Hybrid system indicator indication is normal.

   
   

   NG

   REPLACE COMBINATION METER ASSEMBLY Click here

   OK

3. READ VALUE USING GTS (HYBRID SYSTEM INDICATOR)

   
   

   1. Use the Data List to check the hybrid system indicator Click here.

      Combination Meter

      Tester Display	Test Part	Control Range	Diagnostic Note
      Hybrid System Indicator	Hybrid system indicator value / Min.: -512 %, Max.: 511 %	-512 to 511 %	-

      OK
      Hybrid system indicator value displayed on the Techstream is almost the same as hybrid system indicator indication.

      Result	Proceed to
      OK	A
      NG (for 2GR-FXE)	B
      NG (for 2AR-FSE)	C

4. CHECK COMBINATION METER ASSEMBLY

   
   

   1. Replace the combination meter assembly with a new or normally functioning one Click here.

   2. Check the hybrid system indicator operation.

      OK
      The operation of the hybrid system indicator returns to normal.

   
   

   OK

   END (COMBINATION METER ASSEMBLY WAS DEFECTIVE)
