Shift Solenoid Valve Circuit Check - Suzuki Swift User Manual

7B-40 AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC)
1. Output shaft speed sensor
1. PCM coupler disconnected
Separately from the above inspection, output shaft speed sensor
itself can be checked on its resistance by disconnecting coupler.
NOTE:
D Function of output shaft speed sensor can be checked by
measuring generated pulse as voltage.
D For its measurement, use an analog type voltmeter while
spinning wheels on lift and with selector lever in "D" range.

SHIFT SOLENOID VALVE CIRCUIT CHECK

1) With ignition switch turned OFF, disconnect PCM couplers.
2) Bring ohmmeter probes in touch with coupler terminals from har-
ness side and measure each resistance.
Resistance between C02-9 and C02-1
for G10 engine model (C03-4 and
C01-1 for G13 engine model)
(Shift solenoid-A, direct clutch)
Resistance between C02-8 and C02-1
for G10 engine model (C03-11 and
C01-1 for G13 engine model)
(Shift solenoid-B, 2nd brake)
If resistance is out of specification, check shift solenoid itself for
resistance (referring to Step 3 of DTC P0753/P0756 Flow Table)
and wire harness for open or short.
If resistance is within specification, proceed to step 3).
