AUTO TRANS DIAGNOSIS - A-140E
 
RETRIEVING TROUBLE CODES
NOTE: On 1995 models, trouble codes are a 2 digit code.
Before retrieving trouble codes, ensure proper battery
voltage exists for proper self-diagnosis system operation.
Perform diagnostic circuit check before retrieving trouble
codes to ensure proper operation of OD OFF light.
NOTE: On 1996 models, trouble codes are a 4 digit code (OBD-II).
Trouble codes can only be retrieved using scan tool
connected to 16-pin Data Link Connector (DLC3).
For DLC3 location. When trouble code is
present, Malfunction Indicator Light (MIL), located on
instrument panel will light. To retrieve trouble codes using
scan tool, follow scan tool manufacturer's operating
instructions.
Diagnostic Circuit Check (1995)
1) Turn ignition on. Release OD switch on shift lever to OFF
position. Ensure OD OFF light on instrument panel turns on. If OD OFF
light does not illuminate, check OD switch and wiring circuit.
2) Depress OD switch to ON position. Ensure OD OFF light goes
off. If OD OFF light remains on, check OD switch and wiring circuit.
If OD OFF light is blinking, check for stored trouble codes. See ECT
 
ECT ECU Codes (1995)
1) Turn ignition on. DO NOT start engine. Depress OD switch
on shift lever to ON position.
NOTE: Codes can only be retrieved with OD switch on. If OD switch
is off, OD OFF light will be on continuously and will not
blink the code.
2) Install jumper wire between terminals TE1 and E1 of DLC1
or DLC2 connector.
3) Note number of flashes from OD OFF light on instrument
panel. If normal system operation exists, OD OFF light will flash 2
times per second.
4) If system is operating correctly and no code exists, turn
ignition off and remove jumper wire. Perform MANUAL SHIFT TEST to
determine if problem is a electrical or mechanical transaxle problem.
5) If code exists, OD OFF light will blink once every .5.second. Number of blinks equals first digit of code. After a pause of
1.5 seconds, second digit will be displayed.
6) If more than one code exists, next code will be displayed
after pause of 2.5 seconds.  Smallest number code will
display first and system will progress to largest code. Codes will be
repeated.
7) Once code is obtained, determine probable cause and
symptom.
For diagnosis and repair of trouble codes, see DIAGNOSTIC
TESTS. Turn ignition off and remove jumper wire.
NOTE: Once repairs have been performed, codes must be cleared from
ECT ECU memory.
