AB60E AUTOMATIC TRANSMISSION / TRANSAXLE AUTOMATIC TRANSMISSION SYSTEM P0761 Shift Solenoid
"C" Performance (Shift Solenoid Valve S3)

DESCRIPTION

The ECM uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd,
3rd, 4th, 5th or 6th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical problems of the shift
solenoid valves, valve body or automatic transmission (clutch, brake or gear, etc.).
DTC Code DTC Detection Condition Trouble Area

S3 stuck ON malfunction*1:
When the ECM directs the gearshift to switch to
5th or 6th gear, the engine overruns (clutch
slips). · Shift solenoid valve S3 remains closed
The ECM determines there is a malfunction · Shift solenoid valve SLT remains closed
P0761 when either of the following conditions is met. · Valve body is blocked
(1 trip detection logic) · Automatic transmission (clutch, brake
or gear, etc.)
(a) When the ECM directs the transmission to switch to
4th gear, the actual gear is shifted to 3rd.
(b) When the ECM directs the transmission to switch to
5th gear, the engine overruns (clutch slips).

S3 stuck OFF malfunction*2:

Shifting to 1st, 2nd, and 3rd gears is
impossible.
The ECM determines there is a malfunction · Shift solenoid valve S3 remains open
when the following conditions are both met. (1 · Valve body is blocked
P0761 trip detection logic) · Automatic transmission (clutch, brake
or gear, etc.)
(a) When the ECM directs the transmission to switch to
2nd gear, the actual gear is shifted to 4th.
(b) When the ECM directs the transmission to switch to
6th gear, the actual gear is shifted to 6th.

MONITOR DESCRIPTION

This DTC indicates "stuck ON malfunction" or "stuck OFF malfunction" of the shift solenoid valve S3.
The ECM commands gear shifts by turning the shift solenoid valves "ON/OFF". When the gear position commanded by the ECM
and the actual gear position are not same, the ECM illuminates the MIL and stores the DTC.

CAUTION / NOTICE / HINT

ACTIVE TEST

HINT:
Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without
removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be
discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic
time. Data List information can be displayed while performing Active Tests.

a. Warm up the engine.

b. Turn the ignition switch off.

c. Connect the intelligent tester to the DLC3.

d. Turn the ignition switch to ON.

e. Turn the intelligent tester on.

f. Enter the following menus: Powertrain / Engine and ECT / Active Test.

g. According to the display on the intelligent tester, perform the Active Test.
HINT:
While driving, the shift position can be forcibly changed with the intelligent tester.
Comparing the shift position commanded by the Active Test with the actual shift position enables you to confirm the
problem (See page Drivetrain>AB60E AUTOMATIC TRANSMISSION / TRANSAXLE>AUTOMATIC TRANSMISSION
SYSTEM>FAIL-SAFE CHART).

HINT:
· This test can be conducted when the vehicle speed is 50 km/h (30 mph) or less.
· The 4th to 5th and 5th to 6th up-shift must be performed with the accelerator pedal released.
· The 6th to 5th and 5th to 4th down-shift must be performed with the accelerator pedal released.
· Do not operate the accelerator pedal for at least 2 seconds after shifting and do not shift successively.
· The shift position commanded by the ECM is shown in the Data List display on the intelligent tester.
· The shift solenoid valve SL2 turns ON/OFF normally when the shift lever is in D.

PROCEDURE

1.CHECK DTC OUTPUT (IN ADDITION TO DTC P0761)

a. Connect the intelligent tester to the DLC3.

b. Turn the ignition switch to ON.

c. Turn the intelligent tester on.

d. Enter the following menus: Powertrain / Engine and ECT / DTC.

e. Read the DTCs using the intelligent tester.

Result

2.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (SHIFT SOLENOID VALVE SLT)

NOTICE:
· Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F).
· Be careful to prevent SST hose from interfering with the exhaust pipe.
· Perform the test with the A/C OFF.
