DTC 16 - Electronic-Controlled A/T Signal
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 check.
DTC 16 - ELECTRONIC-CONTROLLED A/T SIGNAL TROUBLE SHOOTING
| DTC No. | Detecting Condition(s) | Trouble Area |
|---|---|---|
| 16 | Fault in communications between engine CPU and A/T CPU in the ECM | ECM |
If the ECM records the diagnostic trouble code "16", it prohibits the torque control of the A/T which performs smooth gear shifting.
