TT Terminal Circuit
CIRCUIT DESCRIPTION
Checks of ECM input and output signals related to the throttle position sensor, brakes, shift position and other
circuits can be performed by measuring the voltages at terminal TT of the DLC2
INSPECTION PROCEDURE
Repair or replace harness or connector.
Check and replace ECM.
Check harness and connector between ECM and DLC2 and body ground
(See page IN±30).

(1) There is no lock±up in the 2 and L positions.
(2) In the following cases, the lock±up will be released regardless of the lock±up pattern.
w When the throttle valve is completely closed.
w When the brake light switch is ON.
(3) Shift up to 3rd will not occur when the engine coolant temp. is below 35°C (95°F) and the vehicle
speed is below 40 km/h (25 mph).
(4) Shift±up to O/D will not occur when the engine coolant temp. is below 60°C (140°F) and the vehicle
speed is below 63 km/h (39 mph)
(5) When the vehicle speed drops to 10 km/h (6 mph) or more below the cruise control set vehicle speed,
shift down from O/D to 3rd occurs.
