DTC Advanced Diagnostics: P07DC: General Description
Two-way clutch position required to shift in each shift position/mode
| Shift position/mode | One-way clutch function | Lock function |
|---|---|---|
| P | YES | YES |
| R | NO | YES |
| N | YES | YES |
| D (1st gear*) | YES | YES |
| D (2nd to 10th gear) | YES | NO |
*: Possible to shift regardless of the two-way clutch position
The two-way clutch switches between forward and reverse by switching to one-way clutch function that idles one side and lock function that disables idle both sides. The two-way clutch switches between forward and reverse by driving two-way clutch actuator valve with shift solenoid valves A, B, and D, and clutch pressure control solenoid valve B. The two-way clutch switching position is monitored by the two-way clutch actuator valve stroke sensor which measures the stroke position of the two-way clutch actuator valve. The two-way clutch position that is required to shift in each shift position/mode is shown in the table. If the actual gear ratio calculated from the values of the mainshaft speed sensor and the countershaft speed sensor when steady driving at 1st gear is a specified value for a specified time, the TCM detects a malfunction and stores DTC.
