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 

TM-49,

"Fail-Safe"

.

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”.

APPLICABLE ITEMS

SELF DIAGNOSTIC RESULTS

Display Item List

Refer to 

TM-50, "DTC Index"

.

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.
