The O/D OFF indicator notifies the driver that the shift control of
transmaxle is in O/D OFF.
BULB CHECK
Approximately 2 seconds after ignition switch ON.
OPERATION AT COMBNATION METER CNA COMMUNICATION CUT-OFF OR UNUSUAL SIGNAL
For actions on CAN communications blackout in the combnation meter, refer to MWI-23, "Fail-safe".
SYSTEM DIAGRAM
SIGNAL PATH
• When a overdrive control switch signal is input to the combination meter, the combination meter transmits
the overdrive control switch signal to the TCM via CAN communication.
• When all of the following conditions are satisfied, t he TCM transmits a O/D OFF indicator signal to the com-
bination meter via CAN communication. The combination meter turns ON the O/D OFF indicator lamp on the
combination meter, according to the signal.
- TCM receives overdrive control switch signal via CAN communication from combination meter.
- Selector lever: D position
LIGHTING CONDITION
When all of the following conditions are satisfied.
• Ignition switch: ON
• Selector lever: D position
• Overdrive control switch is pressed when the O/D OFF indicator lamp is OFF.
SHUTOFF CONDITION
When any of the conditions listed below is satisfied.
• Ignition switch: Other than ON
• Overdrive control switch is pressed when the O/D OFF indicator lamp is ON.
• Selector lever is shifted to other than D position when the O/D OFF indicator lamp is ON.
