(a) Select the Active Test, use the Techstream to generate a control command, and then check the door lock motor function.
Passenger Door (Front door ECU RH)
OK:
Front door lock RH operates normally.
NG -- INSPECT FUSE (P DOOR 1, P DOOR 2)
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM (DOOR LOCK POSITION SWITCH)
(a) Use the Data List to check if the door lock position switch is functioning properly.
Passenger Door (Front door ECU RH)
OK:
On the Techstream screen, item changes between ON and OFF according to above chart.
NG -- INSPECT FRONT DOOR LOCK ASSEMBLY RH (DOOR LOCK POSITION SWITCH)
OK -- Continue to next step.
3. CHECK FRONT DOOR ECU RH (OPERATION)
(a) Replace the front door ECU RH with a normally functioning one Components.
(b) Check that all doors can be locked and unlocked by using the master switch.
OK:
All doors can be locked and unlocked with master switch.
NG -- REPLACE MAIN BODY ECU
OK -- END (FRONT DOOR ECU RH IS DEFECTIVE)
4. INSPECT FUSE (P DOOR 1, P DOOR 2)
(a) Remove the P DOOR 1 and P DOOR 2 fuses from the passenger side junction block.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE FUSE
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (FRONT DOOR ECU RH - BATTERY)
(a) Disconnect the N1 ECU connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE FRONT DOOR ECU RH Components
8. INSPECT FRONT DOOR LOCK ASSEMBLY RH (DOOR LOCK POSITION SWITCH)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE FRONT DOOR LOCK ASSEMBLY RH Components
OK -- Continue to next step.
9. CHECK HARNESS AND CONNECTOR (FRONT DOOR ECU RH - FRONT DOOR LOCK RH)
(a) Disconnect the N2 ECU connector.
(b) Disconnect the N8 door lock connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
