P2759 |
Open or short is detected in shift solenoid valve SLU circuit for 1 second or more while driving (1 trip detection logic). |
|
MONITOR DESCRIPTION
When an open or short in a shift solenoid valve SLU circuit is detected, the ECM determines there is a malfunction. The ECM will illuminate the MIL and store this DTC.

CAUTION / NOTICE / HINT
NOTICE:
- Perform the universal trip to clear permanent DTCs (See page
).
- Perform registration and/or initialization when parts related to the
automatic transmission are replaced (See page
).
HINT:
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
- Perform the Lock-up Function in Road Test (See page
).
- Check for DTCs again (See page ).
PROCEDURE
