General Description

The transmission control module (TCM) judges the two-way clutch position by the output voltage from the two-way clutch actuator valve stroke sensor. If both the two-way clutch actuator valve stroke sensor A output voltage and the two-way clutch actuator valve stroke sensor B output voltage are in a specified range for a specified duration, the TCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type

Execution	Continuous
Sequence	None
Duration	0.5 second or more
DTC Type	One drive cycle, MIL on, shift position indicator blinks

Enable Conditions

Condition	Minimum	Maximum
Engine speed [Engine Speed]	500 rpm	-
12 volt battery voltage [Battery Voltage]	10 V	-
Other	Clutch pressure control solenoid valve A actual current value is 400 mA or more, or shift solenoid valve D is ON condition
	Not while switching to two-way clutch
	Engine speed, 12 volt battery voltage, and other conditions in Enable Conditions should be satisfied continuous for at least 1.5 seconds

[ ]: HDS Parameter

Malfunction Threshold

Both of conditions are met for at least 0.5 second:

The two-way clutch actuator valve stroke sensor A output voltage is 2.4 V or more, or 2.6 V or less.
The two-way clutch actuator valve stroke sensor B output voltage is 2.4 V or more, or 2.6 V or less.

Possible Cause

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Solenoid wire harness failure
Valve body assembly failure (two-way clutch actuator valve stroke sensor)
TCM internal circuit failure

Confirmation Procedure

Operating Condition

Start the engine.
Test-drive the vehicle in D position/mode at speeds over 6 mph (10 km/h), then slow down and stop the vehicle.
While pressing the brake pedal, shift the transmission to R position/mode.

Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for setting the DTC

When a malfunction is detected, the MIL comes on, the shift position indicator blinks, and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the TCM memory.

Conditions for clearing the DTC

The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command.
