NOTE: Across each row in the chart. the systems that could be sources of a symptom are ranked in the order they should
be inspected staning with O. Find the symptom in the left column, read across to the most likely source. then refer
to the page listed at the top of that column. lf inspection shows the system is OK, try the next mosr likely system O, etc,
* lf codes other then those listed above are indicated, count the number of blinks again. It the MIL is in fact blinking
^ these codes, replace the ECM.
qy, lf the MIL is on while the engine is running. connect the SCS shon connector to the service check connector. It no
code is displayed {MlL stays on steady), the back-up system is in operation.
Substitute a known-good ECM and recheck. lf the indication goes away, replace the original ECM.

Troubleshooting
Self-diagnostic Procedures
When the Malfunction Indicator Lamp {MlL) has been reported on, do the following:
'1. Connect the SCS short connecto. to Service Check Connector as shown. (The 2P Service Check Connector is
located under the dash on the passenger side of the car.) Turn the ignition switch on.
DATA LII{KCONNECTOR (3PI
NOTE:Do not attachjumper wire.
2. Note the Diagnostic Trouble Code (DTC): The MIL indicates I code by the length 8nd numbsr ot blinks. The MIL
can indicate multiple component problems by blinking separate codes, one after another. Codes 1 through Igre
indicated by individual shon blinks. Codes 1O through 43 are indicated by a series of long and shon blinks. Th€
number of long blinks equals the first digit, the number ot short blinks equals the second digit. Sometimes the
firsr blink is difficult to see; always count the blinks at least twice to verify the code.
