DESCRIPTION
When the shift lever is in S and moved toward "-" or "+", it is possible to select different shift ranges (S1 to S8).
Moving the shift lever toward "+" increases the shift range by one, and moving the shift lever toward "-" decreases the shift range by one.

PROCEDURE
1. | READ VALUE USING TECHSTREAM (Shift SW Status (S Range)) |
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / Shift SW Status (S Range).
(e) Read the Data List according to the display on the Techstream.
Powertrain > Engine > Data List Tester Display | Measurement Item | Range | Normal Condition | Diagnostic Note |
---|---|---|---|---|
Shift SW Status (S Range) | Sport (S) mode select switch status | ON or OFF |

---|---|---|
G26-2 (E) - Body ground | Always | Below 1 Ω |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION CONTROL SWITCH - BODY GROUND) |
|
5. | CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM) |
(a) Connect the G26 transmission control switch connector.
(b) Disconnect the A25 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
A25-38 (SFTU) - Body ground | Shift lever held in "+" (Up shift) | Below 1 Ω |
A25-38 (SFTU) - Body ground | Shift lever not held in "+" (Up shift) | 10 kΩ or higher |
A25-37 (SFTD) - Body ground | Shift lever held in "-" (Down shift) | Below 1 Ω |
A25-37 (SFTD) - Body ground | Shift lever not held in "-" (Down shift) | 10 kΩ or higher |
OK | PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM) |
6. | INSPECT TRANSMISSION CONTROL SWITCH (SHIFT LOCK CONTROL UNIT ASSEMBLY) |
(a) Disconnect the G26 transmission control switch connector. |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
4 (IG) - 5 (S) | Shift lever in S, "+" or "-" | Below 1 Ω |
Shift lever not in S, "+" or "-" | 10 kΩ or higher |
NG | REPLACE TRANSMISSION CONTROL SWITCH (SHIFT LOCK CONTROL UNIT ASSEMBLY) |
|
7. | CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH (POWER SOURCE)) |
(a) Disconnect the G26 transmission control switch connector.
