trouble based on
“Diagnosis from
Trouble Codes”.
Go to Step 4
4 1. Turn on the starter switch.
2. The car stops, engine speed is less than 1500 rpm, the AT
selector is N position, and select the TOD switch to the 4L
position.
Do the front lamp and rear lamp in the indicator blink?
Go to Step 5
Examine the
trouble based on
“Trouble
Diagnosis
Depending on the
Status of TOD
Indicator”.
5 1. Step on the brake pedal.

The phenomenon
is not
reproduced.
Refer to “Trouble
intermittently
observed”.
Go to Step 6
6 When the vehicle is moved forth and back, is the transfer changed
to the 4L mode?
The phenomenon
is not
reproduced.
Refer to “Trouble
intermittently
observed”.
Go to Step 7
7 Does the continuity corresponding to the encoder position
between the terminals comply with the 4L position in the following
table (continuity)?
Examine the
trouble based on
“Trouble
diagnosis
Depending on
The Status of
TOD Indicator”.
Go to Step 8
