DESCRIPTION
Changing from 1st to 6th is performed by the ECM turning shift solenoid valves
SL1, SL2, SL3 and SL4 on and off. If an open or short circuit occurs in any of the
shift solenoid valves, the ECM controls the remaining normal shift solenoid valves
to allow the vehicle to be operated (See page )
HINT:
The following table shows normal operation of the shift solenoid valves SL4 when the shift lever is in D.

An open or short circuit (output signal duty is 0% or 100%) is detected by the ECM in the shift solenoid valve SL4 circuit while driving and shifting gears (SL4 output signal duty is more than 3% and less than 100% under normal conditions) (1 trip detection logic). |

MONITOR DESCRIPTION
This DTC indicates an open or short in the shift solenoid valve SL4 circuit. The ECM commands gear shifts by turning the shift solenoid valves on or off. When there is an open or short circuit in any of the shift solenoid valve circuits, the ECM detects the problem and illuminates the MIL and stores the DTC. The ECM also performs the fail-safe function and turns the other normal shift solenoid valves on or off. (In case of an open or short circuit, the ECM stops sending current to the circuit.)
While driving and shifting gears, if the ECM detects an open or short in the
shift solenoid valve SL4 circuit, the ECM determines there is a malfunction (See
page ).
