INSPECTION PROCEDURE
1 INSPECT TRANSMISSION WIRE(S1/S2)
(a) Disconnect the transmission wire connector from the
transaxle.
(b) Measure the resistance between terminal S1/S2 of trans-
mission wire connector and body ground.
OK:

2 CHECK HARNESS AND CONNECTOR(TRANSMISSION WIRE ± ECM)
(a) Connect the transmission wire connector to the transaxle.
(b) Disconnect the ECM connector.
(c) Measure the resistance between terminals.

PATTERN SELECT SWITCH CIRCUIT
CIRCUIT DESCRIPTION
When SNOW mode is selected with the pattern select switch, the ECM controls the solenoid valves and the
transmission starts from 2nd gear.
In D range, the transmission automatically shifts up through 3rd to O/D as usual.
