Transmission Control Switch Circuit

U760E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: Transmission Control Switch Circuit
- Transmission Control Switch Circuit

DESCRIPTION

When the shift lever is in S and it is moved toward "-" or "+", it is possible to select different shift ranges (1st through 6th ranges).

Moving the shift lever toward "+" increases the shift range by one, and moving the shift lever toward "-" decreases the shift range by one.

INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. READ VALUE USING TECHSTREAM (SPORT SHIFT SWITCH STATUS)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine and ECT / Data List.

(e) In accordance with the display on the Techstream, read the Data List.





Result:
