ELECTRIC SHIFT SYSTEM : System Description
INFOID:0000000010119555
• The electric shift system detects each shift position electrically. In addition, in P position, the electric shift
system activates the parking actuator, according to electrical signals received from the P position switch and
brings the vehicle into the parking state.
• In the event of a malfunction in the electric shift system, the shift position indicator (in the combination meter)
turns OFF and only the selector indicator (in the electric shift selector area) indicates the shift position.
• In the event of a malfunction in the electric shift system, the system enters fail-safe mode. Refer to

ELECTRIC SHIFT SYSTEM : Protection Control
INFOID:0000000010119557
If shifting from the P position to another position and shifting from another position to the P position are
repeated within a short period of time, it may become impossible to shift for system protection. In this case, the
system automatically returns to the normal state allowing shifting after approximately 10 seconds.

DIAGNOSIS SYSTEM (ELECTRIC SHIFT)
DIAGNOSIS DESCRIPTION
DIAGNOSIS DESCRIPTION : System Description
INFOID:0000000010119561
This is an on-board trouble diagnosis system which automatically detects malfunction. Detected malfunction is
memorized in ECU as DTC. Diagnosis information can be confirmed using CONSULT.
DIAGNOSIS DESCRIPTION : DTC
INFOID:0000000010119562
• DTC (P0571, P0705, P0780, etc.) is specified by SAE J2012/ISO 15031-6.
• Electric shift control module memorizes DTC when malfunction is detected. It can memorize plural DTCs.
DIAGNOSIS DESCRIPTION : Counter System
INFOID:0000000010119563
Counter system counts up at every operation of power switch from OFF to ON under condition that the same
malfunction is not detected. On the other hand, if the same DTC as memorized one is detected again, the
count is reset and the counter system counts up again from “0”.
CONSULT Function
INFOID:0000000010119564
APPLICABLE ITEMS
SELF DIAGNOSTIC RESULTS
Display Item List
How to Read DTC
DTC is displayed on “Self Diagnostic results” of CONSULT.
When DTC is currently detected, “CRNT” is displayed. If “PAST” is displayed, it shows a malfunction occurred
in the past.The trip number of drive without malfunction of concerned DTC can be confirmed with “IGN
counter” inside “FFD”.
How to Erase DTC
NOTE:
If the power switch is kept ON after repair operation, operate the power switch to OFF. Operate the power
switch to ON again after waiting at least 10 seconds.
1. Touch “SHIFT” of CONSULT.
2. Touch “Self Diagnostic Result”.
3. Touch “Erase”. (DTC memorized in electric shift control module is erased.)
IGN Counter
IGN counter is displayed in “FFD”. It displays the number of operations of power switch from OFF to ON after
DTC recovery to normal.
• If malfunction (DTC) is currently detected, “0” is displayed.
• The displayed number counts up at each operation of power switch from OFF to ON after recovery to nor-
mal, such as 1
→ 2 → 3...38 → 39.
• If the number of operation exceeds 39, the displayed number will be fixed at “39” until the self diagnosis
result is erased.
