Description

IMPROPER SHIFTING TO 3RD GEAR POSITION
- This is a "failure" item indicated by the Malfunction Indicator Lamp (MIL).
- This is indicated when the vehicle is being driven at any gear position other than 3rd while the A/T control unit is instructing the A/T to shift the gear in the 3rd position.
- The detected item, "A/T 3RD SIGNAL", is not determined as a fault unless the A/T control unit self-diagnosis system is in the "No Failure" condition. When "A/T 3RD SIGNAL" is displayed, it indicates that the gears are not properly shifted. The problem is not caused by electrical failure of the A/T (circuits open or shorted) but by mechanical failure (control valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band, etc.).
