INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (SPORTS MODE)

(a) Connect the Techstream to the DLC3.

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

(c) Select the following menu items: Powertrain / Hybrid Control / Data List / Sports Mode.

(d) Read the data list.

OK:





NG -- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
OK -- Continue to next step.

2. READ VALUE USING TECHSTREAM (SPORTS SHIFT UP SIGNAL, SPORTS SHIFT DOWN SIGNAL)

(a) Select the following menu items: Powertrain / Hybrid Control / Data List / Sports Shift UP Signal, Sports Shift Down Signal.

(b) Read the data list.

OK:





NG -- INSPECT TRANSMISSION FLOOR SHIFT ASSEMBLY (TRANSMISSION CONTROL SWITCH)
OK -- Continue to next step.

3. CHECK FOR INTERMITTENT PROBLEMS

(a) Check for intermittent problems Check For Intermittent Problems.

(1) Move the shift lever to the S position and jiggle the wire harness and connector.

(2) Move the shift lever to the + and - positions and jiggle the wire harness and connector.

NG -- REPAIR OR REPLACE MALFUNCTIONING PARTS, COMPONENT AND AREA

OK -- REPLACE HYBRID VEHICLE CONTROL ECU Components

4. INSPECT TRANSMISSION FLOOR SHIFT ASSEMBLY (TRANSMISSION CONTROL SWITCH)

(a) Disconnect the transmission control switch connector.





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

Standard resistance:





NG -- REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY Components
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - HYBRID VEHICLE CONTROL ECU)

(a) Connect the transmission control switch connector.

(b) Disconnect connector A75 from the hybrid vehicle control ECU.





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

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE HYBRID VEHICLE CONTROL ECU Components

6. CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)

(a) Disconnect the transmission control switch connector.





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

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

Standard voltage:





NG -- CHECK POWER SOURCE CIRCUIT
OK -- Continue to next step.

7. INSPECT TRANSMISSION FLOOR SHIFT ASSEMBLY (TRANSMISSION CONTROL SWITCH)

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





Standard resistance:





NG -- REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY Components
OK -- Continue to next step.

8. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - HYBRID VEHICLE CONTROL ECU)

(a) Connect the transmission control switch connector.

(b) Disconnect connector A75 from the hybrid vehicle control ECU.





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

(d) Measure the voltage according to the value(s) in the table below.

Standard voltage:





NOTICE:
Turning the power switch on (IG) with the hybrid vehicle control ECU connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

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

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE HYBRID VEHICLE CONTROL ECU Components
