Vehicles With Electronically Controlled Automatic Transaxles
• Some vehicles have computer
controlled automatic transaxles
(transmissions).
• Typically these transmissions are self-
diagnosing, similar to the engine
control systems covered in this
section.
• Note that certain engine control
system failures may also cause the
"S", "D", or "D
" transmission indicator
4
lamp to flash along with the "CHECK"
Engine lamp. Should this happen
during the trouble code reading
procedures described later, repair the
engine control system trouble codes
first.
• After engine control system repair,
clear the automatic transaxle
computer's memory by removing the
appropriate fuse for 15 seconds.
• Test drive the vehicle, then re-check
the engine control system for trouble
codes. In many cases, once the
engine control system failure is
repaired, the transaxle trouble code
will also disappear.
• If the transaxle trouble code is not
eliminated, then proceed with a self-
diagnostic check on the automatic
transaxle as outlined in the vehicle
service manual.
