P313 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: Pattern Select Switch Circuit
- Pattern Select Switch Circuit
DESCRIPTION
If pattern select switch signals are input to the hybrid vehicle control ECU, the ECU sends signals to the combination meter assembly via CAN communication to turn on the ECON mode light.

INSPECTION PROCEDURE
PROCEDURE
1. READ VALUE USING TECHSTREAM (CAN BUS CHECK)
HINT
ECUs that are correctly connected to the CAN communication system can be displayed on the Techstream.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Enter the following menus: System Select / CAN Bus Check.
Result:
C -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting
B -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting
A -- Continue to next step.
2. CHECK DTC OUTPUT (ALL DTC CODE)
(a) Check for DTCs of all systems by following the prompts on the Techstream screen.
Result:
B -- GO TO DTC CHART
A -- Continue to next step.
3. PERFORM ACTIVE TEST USING TECHSTREAM (METER)
(a) Enter the following menus: Body Electrical / Combination Meter / Active Test / Indicat. ECO.
(b) Check the condition of the pattern select indicator light (ECON mode light) by operating the Techstream.
OK:
Result:
B -- GO TO METER SYSTEM How To Proceed With Troubleshooting
A -- Continue to next step.
4. CHECK PATTERN SELECT SWITCH ASSEMBLY (ECON MODE SWITCH)
(a) Turn the ignition switch off.
(b) Disconnect the pattern select switch assembly (ECON mode switch) connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPLACE PATTERN SELECT SWITCH ASSEMBLY (ECON MODE SWITCH)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - BODY GROUND)
(a) Connect the pattern select switch assembly connector.
(b) Disconnect connector D73 from the hybrid vehicle control ECU.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
