DTC 16

CODE - 16 A/T CONTROL SIGNAL MALFUNCTION

Circuit Description

The signal from the A/T CPU retards the ignition timing of the engine during A/T gear shifting, thus momentarily reducing torque output of the engine for smooth clutch operation inside the transmission and reduced shift shock.




Detecting Condition

If the ECM records the diagnostic trouble code "16" in memory, it prohibits the torque control of the A/T which performs smooth gear shifting.
