Pattern Select Switch Power Mode Circuit

HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: Pattern Select Switch Power Mode Circuit
- Pattern Select Switch Power Mode Circuit

DESCRIPTION

When selecting POWER mode, the POWER mode switch (integration control and panel sub-assembly) operation signal is sent to the ECM. Following this, the drive torque is optimally controlled to obtain a sporty feel in response to the driver's acceleration operation.

B -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting
A -- Continue to next step.

2. CHECK DTC OUTPUT (HEALTH CHECK) Pattern Select Switch EV/HV Mode Circuit

B -- GO TO DTC CHART
A -- Continue to next step.

3. PERFORM ACTIVE TEST USING TECHSTREAM (INDICAT. LAMP ECT PWR)

(a) Connect the Techstream to the DLC3.

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

(c) Enter the following menus: Body Electrical / Combination Meter / Active Test / Indicat. Lamp ECT PWR.

(d) Perform the "Indicat. Lamp ECT PWR" Active Test.

OK:

The POWER mode indicator lamp comes on or blinks.

(e) Turn the power switch off.

NG -- REPLACE NO. 2 METER CIRCUIT PLATE Components
OK -- Continue to next step.

4. READ VALUE USING TECHSTREAM (PATTERN SWITCH (PWR/M))

(a) Connect the Techstream to the DLC3.

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

(c) Enter the following menus: Powertrain / Hybrid Control / Data List / Pattern Switch (PWR/M).

(d) Read the value displayed on the Techstream.
