P0A32

HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P0A32-666, P0A33-665: Drive Motor "B" Temperature Sensor Circuit Low
P0A33-665 - Drive Motor "B" Temperature Sensor Circuit High

DESCRIPTION

Refer to the description for DTC P0A31-668 P0A31-668.

HINT
The term "drive motor B" indicates MGR.

HINT
After confirming that DTC P0A32-666 or P0A33-665 is output, use the Techstream to check "Rear Motor Temp" in the power management control ECU Data List.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK CONNECTOR CONNECTION CONDITION (POWER MANAGEMENT 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 power switch on (IG).

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

(d) Read the Data List.

Result:

(e) Turn the power switch off.

B -- READ VALUE USING TECHSTREAM (CHECK FOR SHORT)

C -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
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 power switch on (IG).

(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 power switch off.

(h) Connect the rear motor temperature sensor connector.

NG -- CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

OK -- REPLACE REAR TRACTION MOTOR WITH TRANSAXLE ASSEMBLY Components

4. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

(a) Connect terminals 22 (RMT) and 23 (RMTG) of the connector A80 of the power management control ECU.

(b) Connect the Techstream to the DLC3.

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

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

(e) Read the Data List.

OK:

(f) Turn the power switch off.

NG -- REPLACE POWER MANAGEMENT CONTROL ECU Components

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 power switch off.

(g) Connect the rear motor temperature sensor connector.

NG -- CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

OK -- REPLACE REAR TRACTION MOTOR WITH TRANSAXLE ASSEMBLY Components

6. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - REAR MOTOR TEMPERATURE SENSOR)

(a) Disconnect the rear motor temperature sensor connector.

(b) Disconnect connector A80 from the power management control ECU.

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

Standard Resistance (Check for Open):

Standard Resistance (Check for Short):
