S Excessive transaxle fluid leaking into the connector,
wicking up into the external wiring harness, and
degrading the wire insulation.
S Water/moisture intrusion in the connector.
S Low pin retention in the external connector from
excessive connection and disconnection of the wir-
ing connector assembly.
S Pin corrosion from contamination.
S Broken/cracked connector assembly.
S Points to remember when working with transaxle
wiring connector assembly.
S To remove the connector, squeeze the two tabs
towards each other and pull straight up (refer to
illustration).Carefully limit twisting or wiggling the connector during re-
moval. Bent pins can occur.
DO NOT pry the connector off with a screwdriver or other
tool.
To reinstall the external wiring connector, first orient the
pins by lining up arrows on each half of the connector.
Push the connector straight down into the transaxle with-
out twisting or angling the mating parts.
The connector should click into place with a positive feel
and/or noise.
Transaxle Control Module (TCM)
The transaxle control module (TCM) is an electronic de-
vice which monitors inputs to control various transaxle
functions including shift quality and transaxle sensors,
switches, and components to process for use within its’
control program. Based on this input information, the TCM
controls various transaxle output functions and devices.
Data Link Connector (DLC)
The data link connector (DLC) is a multiple cavity connec-
tor. The DLC provides the means to access serial data
from the TCM to aid in powertrain diagnosis. The DLC al-
lows the technician to use a scan tool to monitor various
systems and display diagnostic trouble codes (DTCs).
The DLC connector is located within the driver’s compart-
ment, directly below the steering column.
