STEP | CHECK | YES | NO |
1.CHECK POWER SUPPLY CIRCUIT.
Connect DST-i or general scan tool to data link connector.
Does DST-i or the general scan tool turn ON?
Diagnostic Procedure for Subaru Select Monitor Communication > COMMUNICATION FOR INITIALIZING IMPOSSIBLE">Go to Step 4.
Diagnostic Procedure for Subaru Select Monitor Communication > COMMUNICATION FOR INITIALIZING IMPOSSIBLE">Go to Step 2.
2.CHECK POWER SUPPLY CIRCUIT.
Measure the voltage between data link connector and chassis ground.
Connector & terminal
(B40) No. 16 (+) — Chassis ground (−):
Is the voltage 10 V or more?
Diagnostic Procedure for Subaru Select Monitor Communication > COMMUNICATION FOR INITIALIZING IMPOSSIBLE">Go to Step 3.
Repair the power supply circuit.
NOTE:
In this case, repair the following item:
• Open or ground short circuit of harness between battery and data link connector
• Blown out of fuse (M/B No. 13)
3.CHECK HARNESS BETWEEN DATA LINK CONNECTOR AND CHASSIS GROUND.
1) Turn the ignition switch to OFF.
2) Measure the resistance of harness between data link connector and chassis ground.
Connector & terminal
(B40) No. 4 — Chassis ground:
(B40) No. 5 — Chassis ground:
Is the resistance less than 5 ??
Repair the poor contact of data link connector.
Repair the harness and connector.
NOTE:
In this case, repair the following item:
• Open circuit in harness between ECM connector and data link connector
• Open circuit of harness between ECM connector and engine ground
• Poor contact of ECM connector
• Poor contact of coupling connector
4.CHECK HARNESS BETWEEN ECM AND DATA LINK CONNECTOR.
Measure the resistance between data link connector and chassis ground.
Connector & terminal
(B40) No. 7 — Chassis ground:
Is the resistance 1 M? or more?
Repair the poor contact of the ECM or data link connector.
Repair the short circuit to ground in harness between ECM connector and data link connector.
