4B2–81
DRIVE LINE CONTROL SYSTEM (TOD)
Step Action Yes No
1 1. Turn off the starter switch.
2. Disconnect the ECU connector (C–38).
Is the continuity established between the connector terminals
(C–38) 14 and (C–38) 19?
Go to Step 2
Replace TOD
indicator lamp
bulb.

Step 5
2 1. Turn off the starter switch and connect the ECU connector.
2. Turn on the starter switch.
When the TOD switch is selected to the TOD position, is 0V
observed between terminals 30 and 47, and 43 and 47? Does the
voltage between the terminals 7 and 47, 19 and 47, and 8 and 47
comply with the TOD mode in the following table? Go to Step 3
Repair the TOD
switch circuit.
Go to Step 5
3 When the TOD switch is selected to the 2H position, is 12V
observed between terminals 30 and 47, and 0V observed
between terminals 43 and 47? Does the voltage between the
terminals 7 and 47, 19 and 47, and 8 and 47 comply with the 2H
mode in the following table?
Go to Step 4
Repair the TOD
switch circuit.
Go to
Step 5
4 When the TOD switch is selected to the 4L position, is 0V
observed between the terminal 30 and 47 and 12V observed
between the terminal 43 and 47? Does the voltage between the
terminals 7 and 47, 19 and 47, and 8 and 47 comply with the 4L
mode in the following table?
The phenomenon
