Transmission Control Switch Circuit [08/2015 - 08/2017]: Procedure
WARNING: This page is about a different variant/trim than selected.
- INSPECT TRANSMISSION CONTROL SWITCH
- Disconnect the H31 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, "+" and "-" Below 1 Ω 2 (SFTU) - 5 (E) Shift lever continuously in "+"
(Up-shift)Below 1 Ω 1 (SFTD) - 5 (E) Shift lever continuously in "-"
(Down-shift)Below 1 Ω 3 (IG) - 7 (S) Shift lever not in S, "+" and "-" 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
Result:
NG
REPLACE TRANSMISSION FLOOR SHIFT ASSEMBLY (TRANSMISSION CONTROL SWITCH)
(Refer to REMOVAL [08/2015 - ] )
Result:
OK
See step 2
- Disconnect the H31 transmission control switch connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND)
- Disconnect the H31 transmission control switch connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition H31-3 (IG) - Body ground Ignition switch ON 11 to 14 V Ignition switch off Below 1 V - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition H31-5 (E) - Body ground Always Below 1 Ω
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 3
- Disconnect the H31 transmission control switch connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
- Disconnect the A27 ECM connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition A27-25 (S) - Body ground - Ignition switch ON
- Shift lever in S, "+" and "-"
11 to 14 V - Ignition switch ON
- Shift lever not in S, "+" and "-"
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 A27-38 (SFTU) - Body ground Shift lever continuously in "+"
(Up-shift)Below 1 Ω A27-27 (SFTD) - Body ground Shift lever continuously in "-"
(Down-shift)Below 1 Ω A27-38 (SFTU) - Body ground Shift lever in S 10 kΩ or higher A27-27 (SFTD) - Body ground Shift lever in S 10 kΩ or higher
Result:
OK
