PROCEDURE
| 1. | READ VALUE USING TECHSTREAM (SPORTS SHIFT UP SIGNAL, SPORTS SHIFT DOWN SIGNAL) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Powertrain / Hybrid Control / Data List / Sports Shift UP Signal, Sports Shift DOWN Signal.
Powertrain > Hybrid Control > Data List| Tester Display |
|---|
| Sports Shift UP Signal |
| Sports Shift DOWN Signal |
(d) Read the values displayed on the Techstream.
| Result | Proceed to |
|---|---|
| The Techstream display changes according to the shift paddle switch (transmission shift switch assembly) operation | A |
| The Techstream display does not change according to the shift paddle switch (transmission shift switch assembly) operation | B |
(e) Turn the power switch off.
