DESCRIPTION

Refer to the system description for DTC P2714 (See page ).

DTC No.

DTC Detection Condition

Trouble Area

P2716

Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1 trip detection logic).
  • Open or short in shift solenoid valve SLT circuit
  • Shift solenoid valve SLT
  • ECM
MONITOR DESCRIPTION

When an open or short in the shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. The ECM will illuminate the MIL and store the DTC.

WIRING DIAGRAM CAUTION / NOTICE / HINT CAUTION / NOTICE / HINT

NOTICE:

  • Perform the universal trip to clear permanent DTCs (See page Perform registration and/or initialization when parts related to the ).
  • 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.

  1. Start the engine.
  2. Check for DTCs again (See page ).
