Result

Result	Proceed to
OK	A
NG	B

B → See step 2

A → See step 5

CHECK HARNESS AND CONNECTOR (ECM - WIRING HARNESS CONNECTOR)

Disconnect the harness connector from the wiring harness connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance

Tester Connection	Condition	Specified Condition
E26-3 (SL) - E8-6 (SL)	Always	Below 1 Ω
E26-3 (SL) - Body ground and other terminals	Always	10 kΩ or higher
E8-6 (SL) - Body ground and other terminals	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SL)

Remove the wiring harness connector from the transaxle.
