1. Disconnect a wire from the negative plug of joint stock bank.
2. Raise the car.
3. Remove the side mudguard (1).
4. Disconnect the solenoid valve assembly connector (2).
5. Measure the resistance between the solenoid valve assembly connector pins.
Contact | Valve | Resistance, Ohm |
1 | DCCSV | 2,7-3,4 |
2 | PCSV-A | 22,3 ± 1,5 |
3 | PCSV-B | 22,3 ± 1,5 |
4 | SCSV-A | 2,7-3,4 |
5 | SCSV-B | 22,3 ± 1,5 |
6 | SCSV-C | 22,3 ± 1,5 |
6. If the measured value differs from the nominal value, remove the automatic transmission oil pan.
7. Disconnect the valve connector and measure the resistance. If the result is not as specified, replace the valve.
