Code No. P0826: Malfunction of Shift Switch Assembly
DIAGNOSTIC FUNCTION
CVT-ECU detects the UP/DOWN operation of the shift switch assembly. CVT-ECU determines that the malfunction is present if the abnormal value is input.
JUDGEMENT CRITERIA
Input to the shift switch assembly remains abnormal for 1 second.
PROBABLE CAUSES
- Malfunction of selector lever assembly (Faulty shift switch assembly)
- Damaged wiring harness and connectors
- Malfunction of CVT-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE data list
- Item 64: Manual mode switch
- Item 65: Select switch (Up)
- Item 66: Select switch (Down)
OK: The data list changes in response to the selector lever operation.
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction 
).
Go to Step 2.
STEP 2. Shift switch assembly single unit check
STEP 3. Check for open circuit or short to earth in MSW, UPSW, DWSW line between the selector lever assembly connector and the CVT-ECU connector
Is the check result normal?
Go to Step 4. Repair the connector(s) or wiring harness.
STEP 4. Symptom recheck after erasing diagnosis code
