• Final Procedure (After Troubleshooting)
1. Disconnect the SCS short connector from the data link
connector.
• Note that the MIL stays ON while the SCS short con-
nector is connected to the data link connector.
2. Be sure to reset the ECM after troubleshooting.
The MIL can come ON or blink when the ECM detect-
ed poor or loose contact of a connector. If it is hard to
identify the problem part by following the troubleshoot-
ing flow chart, check the three connectors of the ECM
and the connector of the probable faulty part, and
clean or repair the connector(s) if necessary.
If the problem cannot be identified by the above pro-
cedure, check by following the troubleshooting for the
fuel supply system (P. 5-96).
• Connecting Test Harness
Use the test harness (special tool) and a commercially
available digital circuit tester for troubleshooting.
Disconnect the test harness sensor connector if the
instruction tells to do so for troubleshooting.
