Mechanical System. Electric Shift
Structure and Operation
Parking Mechanism
-
The parking mechanism is composed of the manual shaft, manual plate, detent spring, parking rod, parking pawl, and parking gear. It locks/unlocks the parking mechanism by operation of the parking actuator.
-
When the parking actuator operates by the signal from the electric shift control module, the manual shaft and the manual plate connected mechanically with the parking actuator rotates and the parking rod slides.
The parking pawl is pushed by sliding the parking rod and it meshes with the parking gear to lock the parking mechanism.
Diagnosis System (electric Shift Control Module). Consult Function
Diagnosis Description
APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes as follows.
| Diagnostic test mode | Function |
|---|---|
| Self Diagnostic Result |
Display DTC which electric shift control module memorizes.
Self-diagnostic results and freeze frame data can be read and erased quickly.* |
| Data Monitor | Input/Output data in the electric shift control module can be read. |
| Work support | This mode enable a technician to adjust some devices faster and more accurately by following the indication on the CONSULT. |
| ECU Identification | Part number of electric shift control module can be read. |
*: The following diagnosis information is erased by erasing.
-

SELF DIAGNOSTIC RESULT
Refer to DTC Index.
When “Current DTC” is displayed on self-diagnosis result.
-
The system is presently malfunctioning.
When “Past DTC” is displayed on self-diagnosis result.
-
System malfunction in the past is detected, but the system is presently normal.
