7.CHECK POWER SUPPLY CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the TCM connector.
3) Turn the ignition switch to ON. (Engine OFF)
4) Measure the ignition power supply voltage between TCM connector and chassis ground.
Connector & terminal
(B54) No. 8 (+) — Chassis ground (−):
(B54) No. 24 (+) — Chassis ground (−):
(B54) No. 34 (+) — Chassis ground (−):
(B54) No. 40 (+) — Chassis ground (−):
(B54) No. 41 (+) — Chassis ground (−):
Is the voltage 10 — 13 V?
Diagnostic Procedure for Subaru Select Monitor Communication > COMMUNICATION FOR INITIALIZING IMPOSSIBLE">Go to Step 8.
Repair the open circuit of harness between TCM and battery.
8.CHECK HARNESS CONNECTOR BETWEEN TCM AND CHASSIS GROUND.
1) Turn the ignition switch to OFF.
2) Measure the resistance of harness between TCM connector and chassis ground.
Connector & terminal
(B54) No. 42 — Chassis ground:
Is the resistance less than 10 ??
Diagnostic Procedure for Subaru Select Monitor Communication > COMMUNICATION FOR INITIALIZING IMPOSSIBLE">Go to Step 9.
Repair the open circuit of the TCM ground circuit and poor contact of connector.
9.CHECK POOR CONTACT OF CONNECTOR.
Is there poor contact of control module power supply, ground circuit and data link connector?
Repair the connector.
Replace the TCM. Transmission Control Module (TCM)">
