Transmission Control Switch Circuit [10/2015 - ]: Procedure
WARNING: This page is about a different variant/trim than selected.
- CHECK HARNESS AND CONNECTOR (BATTERY - TRANSMISSION CONTROL SWITCH)
- Disconnect the transmission control switch connector.
*a Front view of wire harness connector
(to Transmission Control Switch) - Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition G36-4 (IG) - Body ground Ignition switch ON 11 to 14 V G36-4 (IG) - Body ground Ignition switch off Below 1 V
Result:
NG
CHECK POWER SOURCE CIRCUIT
Result:
OK
See step 2
- Disconnect the transmission control switch connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BODY GROUND)
- Disconnect the transmission control switch connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G36-2 (E) - Body ground Always Below 1 Ω *a Front view of wire harness connector
(to Transmission Control Switch)
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 3
- INSPECT TRANSMISSION CONTROL SWITCH (TRANSMISSION FLOOR SHIFT ASSEMBLY)
- Disconnect the transmission control switch connector.
- 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 3 (SFTU) - 2 (E) Shift lever held in "+" (Up-shift) Below 1 Ω 1 (SFTD) - 2 (E) Shift lever held in "-" (Down-shift) Below 1 Ω 4 (IG) - 5 (S) Shift lever not in S, "+" or "-" 10 kΩ or higher 3 (SFTU) - 2 (E) Shift lever in S 10 kΩ or higher 1 (SFTD) - 2 (E) Shift lever in S 10 kΩ or higher *a Component without harness connected
(Transmission Control Switch)
Result:
NG
REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY: REMOVAL [12/2012 - ]
Result:
OK
See step 4
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
- Disconnect the ECM connector.
*a Front view of wire harness connector
(to ECM) - Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition A62-27 (S) - Body ground - Ignition switch ON
- Shift lever in S, "+" or "-"
11 to 14 V A62-27 (S) - Body ground - Ignition switch ON
- Shift lever not in S, "+" or "-"
Below 1 V - Turn the ignition switch off.
- w/ Shift Paddle Switch:
Disconnect the G8 spiral cable sub-assembly connector.
Refer to REMOVAL [12/2012 - ]
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition A62-42 (SFTU) - Body ground Shift lever held in "+" (Up-shift) Below 1 Ω A62-43 (SFTD) - Body ground Shift lever held in "-" (Down-shift) Below 1 Ω A62-42 (SFTU) - Body ground Shift lever in S 10 kΩ or higher A62-43 (SFTD) - Body ground Shift lever in S 10 kΩ or higher
Result:
OK
