Hybrid System Indicator Malfunction

METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Hybrid System Indicator Malfunction
- Hybrid System Indicator Malfunction

DESCRIPTION

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

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Combination Meter / Active Test.

(e) Check the indicator light operation according to the values in the table below.

Combination Meter





OK:

Hybrid system indicator indication is normal.

NG -- REPLACE METER CIRCUIT PLATE Disassembly
OK -- Continue to next step.

3. READ VALUE USING TECHSTREAM (HYBRID SYSTEM INDICATOR)

(a) Connect Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Combination Meter / Data Test.

(e) Check the values by referring to the table below.

Combination Meter





OK:

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

NG -- GO TO HYBRID CONTROL SYSTEM How To Proceed With Troubleshooting
OK -- Continue to next step.

4. REPLACE METER CIRCUIT PLATE

(a) Replace the meter circuit plate with a new or a known good one Disassembly.

OK:

The operation of the hybrid system indicator returns to normal.
