DTC 16
ELECTRONIC CONTROLLED TRANSMISSION
Control Signal Malfunction
CIRCUIT DESCRIPTION
The signal from the Electronic Controlled Transmission CPU retards the ignition timing of the engine during Elec-
tronic Controlled Transmission gear shifting, thus momentarily reducing torque output of the engine for smooth
clutch operation inside the transmission and reduced shift shock.
Code No. Diagnostic Trouble Code Detecting Condition Trouble Area
16
Fault in communications between the engine CPU and
Electronic Controlled Transmission CPU in the ECM.
ECM
If the ECM records the diagnostic code “16” in memory, it prohibits the torque control of the Electronic Controlled
Transmission which performs smooth gear shifting.
