INSPECTION PROCEDURE

PROCEDURE

1. CHECK CONNECTOR CONNECTION CONDITION (HYBRID VEHICLE CONTROL ECU CONNECTOR) P0340-886

NG -- CONNECT SECURELY
OK -- Continue to next step.

2. READ VALUE USING TECHSTREAM (REAR MOTOR TEMP)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Enter the following menus: Powertrain / Hybrid Control / Data List / Rear Motor Temp.

(d) Read the Data List.

Result:

(e) Turn the ignition switch off.

C -- CHECK FOR INTERMITTENT PROBLEMS Check For Intermittent Problems

B -- READ VALUE USING TECHSTREAM (CHECK FOR SHORT)
A -- Continue to next step.

3. READ VALUE USING TECHSTREAM (CHECK FOR OPEN)

(a) Disconnect the rear motor temperature sensor connector.

(b) Connect terminals 1 (RMT) and 3 (RMTG) of the vehicle side connector of the rear motor temperature sensor.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Enter the following menus: Powertrain / Hybrid Control / Data List / Rear Motor Temp.

(f) Read the Data List.

OK:

HINT
The rear motor temperature sensor is not available separately. If it requires replacement, replace the rear traction motor with transaxle assembly.

(g) Turn the ignition switch off.

(h) Connect the rear motor temperature sensor connector.

NG -- CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

OK -- REPLACE REAR TRACTION MOTOR WITH TRANSAXLE ASSEMBLY Removal

4. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

(a) Connect terminals 22 (RMT) and 23 (RMTG) of connector A65 of the hybrid vehicle control ECU.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Enter the following menus: Powertrain / Hybrid Control / Data List / Rear Motor Temp.

(e) Read the Data List.

OK:

(f) Turn the ignition switch off.

NG -- REPLACE HYBRID VEHICLE CONTROL ECU Removal

OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR

5. READ VALUE USING TECHSTREAM (CHECK FOR SHORT)

(a) Disconnect the rear motor temperature sensor connector.

HINT
The rear motor temperature sensor is not available separately. If it requires replacement, replace the rear traction motor with transaxle assembly.

(f) Turn the ignition switch off.

(g) Connect the rear motor temperature sensor connector.

NG -- CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

OK -- REPLACE REAR TRACTION MOTOR WITH TRANSAXLE ASSEMBLY Removal

6. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

(a) Disconnect the rear motor temperature sensor connector.

(b) Disconnect connector A65 from the hybrid vehicle control ECU.

(c) Measure the resistance according to the value(s) in the table below.
