Toyota Tundra. Manual — part 2817

HINT:



Gear positions in the event of a solenoid valve mechanical problem:

GEAR SHIFT POSITIONS TABLE



Gear position during fail-safe operation:

If any malfunction is detected, the ECM changes into the fail-safe mode to shift into the gear positions as
shown in the table below.

GEAR SHIFT POSITIONS TABLE

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.

MONITOR STRATEGY

MONITOR STRATEGY TABLE

b. When the ECM directs the transmission to switch to

6th gear, the actual gear is shifted to 6th.

INSPECTION PROCEDURE

1. ACTIVE TEST

HINT:

Using the Techstream 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 Techstream to the DLC3.

d. Turn the ignition switch to ON.

e. Turn the Techstream on.

Turbine speed/Output speed (NT/NO)

0.93 or more, and 1.07 or less (This means actual gear is 4th)

Turbine speed/Output speed (NT/NO)

0.51 or more, and 0.65 or less (This means actual gear is 6th)

Turbine speed/Output speed (NT/NO)

1.24 or more, and 1.49 or less (This means actual gear is 3rd)

Turbine speed - Output speed x 4th gear ratio (NT - NO x 4th
gear ratio)

1000 RPM or more

Turbine speed - Output speed x 5th gear ratio (NT - NO x 5th
gear ratio)

1000 RPM or more
