P0826 UP AND DOWN SHIFT SW

Diagnosis Procedure

INFOID:0000000012201191

1.

CHECK DTC (COMBINATION METER)

With CONSULT

1. Turn ignition switch ON.

2. Select “Self Diagnostic Results” in “METER/M&A”.
Is any DTC detected?

YES

>> Check DTC detected item. Refer to

.

NO

>> GO TO 2.

2.

CHECK MANUAL MODE SWITCH SIGNALS

With CONSULT

1. Turn ignition switch ON.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Check the On/Off operations of each monitor item.

*

: With paddle shifter

Without CONSULT

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 and paddle shifter* are shifted to the “+ (up)” or “

−

 (down)”

side [1st 

⇔

 7th gear].

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO-1 (Manual mode switch is abnormal)>>GO TO 3.

NO-2 (Paddle shifter is abnormal)>>GO TO 8.

3.

CHECK MANUAL MODE SWITCH POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect CVT shift selector connector.

3. Turn ignition switch ON.

4. Check voltage between CVT shift selector harness connector terminal and ground.
