DIAGNOSIS FUNCTION

N RANGE LAMP

The N range lamp flashes at a frequency of approximately
1 Hz if there is an abnormality in any of the items in the
table below which are related to the A/T system. Check the
diagnosis code output if the N range lamp is flashing at a
frequency of approximately 1 Hz.

N range lamp flashing items

Input shaft speed sensor

Output shaft speed sensor

Each solenoid valve

Caution
If the N range lamp is flashing at a frequency of
approximately 2 Hz (faster than at 1 Hz), it means that
the A/T fluid temperature is too high. Stop the vehicle
in a safe place and wait until the N range lamp switches
off.

METHOD OF READING THE DIAGNOSIS CODE

Use the MUT-

II

or the N range lamp to take a reading of

the diagnosis codes. (Refer to GROUP 00 – How to Use
Troubleshooting/Inspection Service Points.)
