Overdrive (O/D) Switch
The Overdrive (O/D) switch transmits a signal to the PCM to select or suppress 4th gear in selector lever position D.
The signal of the O/D switch is used for the following functions:
- as an input signal to convey the driver's intent to the PCM.
- to display the driver's intent with the O/D indicator in the Instrument Cluster (IC).
No substitute signal is available for the O/D switch. If it should fail, it is always possible to shift into 4th gear in selector lever position D.
