Description
Shifting from 1st to o/d is performed in combination with the on and off operation of the shift solenoid valves sl1 and sl2, which are controlled by the ecm. 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 safely (see page ax-31).
Monitor description
This dtc indicates an open or short in the shift solenoid valve sl2 circuit. The ecm commands gear shifts 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, illuminates the mil and stores the dtc. Also, the ecm performs the fail-safe function and turns the other normal shift solenoid valves on/off. In case of an open or short circuit, the ecm stops sending current to the circuit (see page ax-31).

Standard resistance: 5.0 To 5.6 Ùat 20°c (68°f)
Ok: valve moves and makes operating noise.
Repair or replace transmission wire
On-vehicle inspection
Check fan and generator v belt
Visually check the drive belt for excessive wear,
frayed cords, etc.
If any defect has been found, replace the drive belt.
Hint:
Cracks on the rib side of a drive belt are considered
acceptable.

Active test
Hint:
Performing the intelligent tester active test allows
relay, vsv, actuator and other items to be operated
without removing any parts. Performing the active
test early in troubleshooting is one way to save time.
The data list can be displayed during the active
test.
