Time Lag Test: Troubleshooting
Time Lag Test Troubleshooting Table (1 Of 2)
| Condition | Possible cause | Correction / Reference Item |
|---|---|---|
| N --> "D" time lag exceeds specification | Malfunction of pressure control solenoid valve (Low line pressure) | Inspect. If NG, replace valve body assembly. |
| Malfunction of primary regulator valve (Low line pressure) | Replace valve body assembly. | |
