Transmission Control Switch Circuit [08/2015 - 08/2019]: Procedure
WARNING: This page is about a different variant/trim than selected.
- INSPECT TRANSMISSION CONTROL SWITCH
- Disconnect the F76 transmission control switch connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 3 (IG) - 7 (S) Shift lever in S, "+" or "-" Below 1 Ω 2 (SFTU) - 5 (E) Shift lever held in "+"
(Up-shift)Below 1 Ω 1 (SFTD) - 5 (E) Shift lever held in "-"
(Down-shift)Below 1 Ω 3 (IG) - 7 (S) Shift lever not in S, "+" or "-" 10 kΩ or higher 2 (SFTU) - 5 (E) Shift lever in S 10 kΩ or higher 1 (SFTD) - 5 (E) Shift lever in S 10 kΩ or higher TEXT IN ILLUSTRATION*a Component without harness connected
(Transmission Control Switch)
Result:
NG
REPLACE TRANSMISSION CONTROL SWITCH (TRANSMISSION FLOOR SHIFT ASSEMBLY)
(Refer to REMOVAL [08/2015 - ] )
Result:
OK
See step 2
- Disconnect the F76 transmission control switch connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND)
- Disconnect the F76 transmission control switch connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition F76-3 (IG) - Body ground Ignition switch ON 11 to 14 V F76-3 (IG) - Body ground Ignition switch off Below 1 V - Turn the ignition switch off.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F76-5 (E) - Body ground Always Below 1 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Transmission Control Switch)
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 3
- Disconnect the F76 transmission control switch connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
- Disconnect the F50 ECM connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition F50-24 (S) - Body ground - Ignition switch ON
- Shift lever in S, "+" or "-"
11 to 14 V F50-24 (S) - Body ground - Ignition switch ON
- Shift lever not in S, "+" or "-"
Below 1 V - Turn the ignition switch off.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F50-16 (SFTU) - Body ground Shift lever held in "+"
(Up-shift)Below 1 Ω F50-22 (SFTD) - Body ground Shift lever held in "-"
(Down-shift)Below 1 Ω F50-16 (SFTU) - Body ground Shift lever in S 10 kΩ or higher F50-22 (SFTD) - Body ground Shift lever in S 10 kΩ or higher TEXT IN ILLUSTRATION*a Rear view of wire harness connector
(to ECM)
Result:
OK
