Attention. Do not damage or deform the connector while checking.
1. Disconnect a socket of the e/valve of blocking and the e/valve A of a gear change.
2. Measure the resistance between the corresponding connector pin and «weight».
- Standard resistance: 12-25 Σ
If resistance differs from specified above, replace the blocking e/valve and the e/valve A of a gear change.
3. Apply battery voltage to the corresponding connector pin and make sure by sound that the e / valve has worked.
If there is no operation sound, replace the e/valve.
