Shift Interlock: Testing and Inspection

A750F AUTOMATIC TRANSMISSION: SHIFT LOCK SYSTEM: ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. CHECK SHIFT LOCK OPERATION
(a) Move the shift lever to P.
(b) Turn the ignition switch OFF.
(c) Check that the shift lever cannot be moved to any position other than P.
(d) Turn the ignition switch ON, depress the brake pedal and check that the shift lever can be moved to other positions.
2. CHECK SHIFT LOCK RELEASE BUTTON OPERATION
(a) When operating the shift lever with the shift lock release button pressed, check that the lever can be moved to any position other than P.
If the operation cannot be performed as specified, check the shift lever assembly.
3. CHECK KEY INTERLOCK OPERATION
(a) Turn the ignition switch ON.
(b) Depress the brake pedal and move the shift lever to any position other than P.
(c) Check that the ignition switch cannot be turned OFF.
(d) Move the shift lever to P, turn the ignition switch OFF and check that the key can be removed.
If the results are not as specified, inspect the shift lock control ECU.





4. CHECK SHIFT LOCK CONTROL ECU (for Column Shift Type)
(a) Measure the voltage according to the value(s) in the table below.
HINT: Measure the voltage of the connector.

Standard voltage:





If the result is not as specified, replace the shift lock control ECU.
(b) Measure the resistance according to the value(s) in the table below.
NOTE: Do not disconnect the shift lock control ECU connector.

Standard resistance:





If the result is not as specified, replace the shift lock control ECU.





5. CHECK SHIFT LOCK CONTROL ECU (for Floor Shift Type)
(a) Measure the voltage according to the value(s) in the table below.
HINT: Measure the voltage of the connector.

Standard voltage:





If the result is not as specified, replace the shift lock control ECU.
(b) Measure the resistance according to the value(s) in the table below.
NOTE: Do not disconnect the shift lock control ECU connector.

Standard resistance:





If the result is not as specified, replace the shift lock control ECU.





6. CHECK SHIFT LOCK SOLENOID (for Column Shift Type)
(a) Disconnect the transmission control switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:





If the result is not as specified, replace the shift lock solenoid.





7. CHECK SHIFT LOCK SOLENOID (for Floor Shift Type)
(a) Disconnect the shift lock solenoid connector from the shift lock control ECU.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:





If the result is not as specified, replace the floor shift assembly.





8. CHECK KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:





If the result is not as specified, replace the solenoid.
(c) Connect the battery's positive (+) lead to terminal 1 (SOL+) and the battery's negative (-) lead to terminal 2 (SOL-).
Check that the operating noise of the solenoid can be heard.
If the result is not as specified, replace the solenoid.
