P0826 MANUAL MODE SWITCH

P0826 MANUAL MODE SWITCH

Description

INFOID:0000000000988694

Manual mode switch is installed in shift control device. The manual mode switch sends shift up and shift down
switch signals to TCM.
TCM sends the switch signals to combination meter via CAN communication line. Then manual mode switch
position is indicated on the shift position indicator.

YES

>> Go to 

TM-252, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-39, "Intermittent Incident"

.

Diagnosis Procedure

Without CONSULT-III

Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the
position mutually coincide when the selector lever is shifted to the “+ (up)” or “- (down)” side (1st 

⇔

 6th gear).

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 2.
