DESCRIPTION Each unit of the navigation system connected to the AVC-LAN (communication bus) transfers the switch signals using the AVC-LAN. If a short to +B or short to ground occurs in the AVC-LAN, the navigation system will not function normally because communication is not possible. WIRING DIAGRAM ![]() CAUTION / NOTICE / HINT HINT: The navigation receiver assembly is the master unit. PROCEDURE
![]() (a) for Column Shift Type: (1) Remove the navigation receiver assembly with the connector(s) still connected (See page
(b) for Floor Shift Type: (1) Remove the navigation receiver assembly with the connector(s) still connected (See page
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
(a) Disconnect the J135 navigation receiver assembly connector. (b) Disconnect the J141 stereo component amplifier assembly connector. (c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
(a) Disconnect and reconnect each slave unit one by one until the master unit returns to normal operation. HINT:
OK: Master unit returns to normal operation. Result

Toyota Tundra Service Manual > Automatic Transmission System: Shift Solenoid "D" Performance (Shift Solenoid Valve S4) (P0766,P0776)
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 ...
