Electrical Components Location (A241L): 1 - overdrive switch, 2 - overdrive solenoid valve, 3 - engine start prohibition switch.
1. Check the engine start inhibit switch.
Check the continuity between the connector terminals indicated in the table in each selector position.
| Selector position | Conclusions |
| P | 2-8 6-1 |
| R | 6-5 |
| N | 2-3 6-7 |
| D | 6-8 |
| 2 | 6-9 |
| L | 6-4 |
2. Check the overdrive solenoid valve.
- a) Disconnect the valve connector.
- b) Measure the resistance between terminals "1" and "3". Nominal resistance is 11-15 Ohm.
- c) When applying battery voltage to terminals "1" and "3" of the electromagnetic valve connector, a click of the valve being triggered should be heard. If there is no click, replace the valve.
- d) Connect the solenoid valve connector.
3. Check the overdrive switch.
- a) Remove the center console.
- b) Using an ohmmeter, check the conductivity between terminals "1" and "3" of the switch connector. When the mode is on, there should be no conductivity; when the mode is off, there should be conductivity; otherwise, replace the switch.
- c) Install the center console.
