INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
a. Turn the ignition switch off.
b. Connect the hand-held tester together with the CAN VIM (controller area network vehicle interface
module) to the DLC3.

MONITOR DESCRIPTION
This DTC indicates an open or short in the shift solenoid valve SL1 circuit. The ECM commands gearshift by
turning the shift solenoid valves "ON/OFF". When there is an open or short circuit in any shift solenoid valve
circuit, the ECM detects the problem and illuminates the MIL and stores the DTC. And the ECM performs the
fail-safe function and turns the other shift solenoid valves in good condition "ON/OFF". (In case of an open or
short circuit, the ECM stops sending current to the circuit.)
While driving and shifting between 4th and 5th gears, if the ECM detects an open or short in the shift solenoid
valve SL1 circuit, the ECM determines there is a malfunction (see FAIL
-SAFE CHART ).
