Without Scan Tool

DIAGNOSIS FUNCTION





N (Neutral) range light

The N range light flashes at a frequency of approximately 1 Hz (once per second) if there is an abnormality in any of the items in the table below which are related to the A/T system. Check for diagnostic trouble codes if the N range light is flashing at a frequency of approximately 1 Hz.

N range light flashing items
Input shaft speed sensor
Output shaft speed sensor
Each solenoid valve
Gear incorrect ratio
A/T control relay system

CAUTION: If the N range light is flashing at a frequency of approximately 2 Hz (two flashes per second), it means that the automatic transmission fluid temperature is too high. Stop the vehicle in a safe place and wait until the N range light switches off.

CAUTION: Turn off the ignition switch before connecting or disconnecting the scan tool.
