ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK SHIFT LOCK OPERATION

(a) Move the shift lever to P.

(b) Turn the ignition switch off.

(c) Check that the shift lever cannot be moved from P.

(d) Turn the ignition switch to ON, depress the brake pedal and check that the shift lever can be moved to other positions.

If the operation cannot be performed as specified, inspect the shift lever assembly and shift lock control unit.

2. CHECK SHIFT LOCK RELEASE BUTTON OPERATION

(b) Depress the brake pedal and move the shift lever to any position other than P.

(c) Check that the ignition switch cannot be turned off.

(d) Move the shift lever to P, turn the ignition switch off and check that the key can be removed.

If the results are not as specified, inspect the shift lock control ECU.

    Toyota Tundra Service Manual > Automatic Transmission System: Shift Solenoid "A" Performance (Shift Solenoid Valve S1) (P0751)
    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 val ...
