Diagnostic Procedure with Diagnostic Trouble Code (DTC)
AUTOMATIC TRANSMISSION (DIAGNOSTICS)
Step
3 CHECK DTC OF ABS.
4 CHECK OUTPUT OF LATERAL G SENSOR
USING SUBARU SELECT MONITOR.
1) Select {Current Data Display & Save} in
Subaru Select Monitor.
2) Read the lateral G sensor output on Subaru
Select Monitor.
5 CHECK POOR CONTACT OF CONNECTOR.
Turn the ignition switch to OFF.
6 CHECK ABSCM&H/U.
1) Connect all connectors.
2) Perform the Clear Memory Mode.
3) Perform the Inspection Mode.
4) Read the DTC.
7 CHECK OTHER DTC DETECTION.
8 CHECK OPEN CIRCUIT IN LATERAL G SEN-
SOR OUTPUT HARNESS AND GROUND
HARNESS.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from TCM.
3) Measure the resistance between TCM con-
nector terminals.
Connector & terminal
(B54) No. 13 — (B55) No. 6:
9 CHECK GROUND SHORT OF HARNESS.
Measure the resistance between TCM connec-
tor and chassis ground.
Connector & terminal
(B54) No. 13 — Chassis ground:
10 CHECK LATERAL G SENSOR.
1) Remove the console box.
2) Remove the lateral G sensor from vehicle.
3) Connect the connector to lateral G sensor.
4) Connect the TCM connector.
5) Turn the ignition switch to ON.
6) Measure the voltage between lateral G
sensor connector terminals.
Connector & terminal
(B359) No. 3 (+) — No. 2 (–):
11 CHECK LATERAL G SENSOR.
Measure the voltage between lateral G sensor
connector terminals.
Connector & terminal
(B359) No. 3 (+) — No. 2 (–):
Check
Is DTC of ABS detected?
Is the reading indicated on
monitor display 2.3 to 2.7 V
when lateral G sensor is level?
Is there poor contact in con-
nector between TCM and lat-
eral G sensor?
Is the same DTC displayed?
Is any other DTC displayed?
Is the resistance between 5.0
and 6.0 kΩ?
Is the resistance more than 1
MΩ?
Is the voltage 2.3 — 2.7 V
when lateral G sensor is in hor-
izontal position?
Is the voltage 3.3 — 4.3 V
when lateral G sensor is
inclined 90° to right?
