Pattern Select Switch Circuit (PWR Mode Switch)
CIRCUIT DESCRIPTION
The ECM memory contains the shift programs for the NORMAL and POWER patterns, 2 position, L position
and the lock-up patterns. Following the programs corresponding to the signals from the pattern select
switch, the park/neutral position and other various sensors, the ECM switches the solenoid valves ON and
OFF, and controls the transmission gear change and the lock-up clutch operation.

INSPECTION PROCEDURE
1 Check pattern select switch (PWR mode switch).
PREPARATION:
Disconnect the pattern select switch connector.
CHECK:
Check continuity between terminals 3 and 5 of pattern select
switch connector when the select switch is set to PWR and
NORM positions.
OK:
Pattern select switchSpecified condition
PWRContinuity
NORMNo continuity
NG Replace the pattern select switch.
OK
2 Check harness and connector between terminal PWR of ECM and body ground.
PREPARATION:
(a) Connect the pattern select switch connector.
(b) Disconnect the connector of ECM.
CHECK:
Check continuity between terminal PWR of ECM and body
ground when the pattern select switch is set to the PWR (POW-
ER) position and NORM (NORMAL) position.
OK:
Pattern select switchSpecified condition
PWRContinuity
NORMNo Continuity
HINT:
The ECM uses the normal pattern signal if the PWR signal is not
input.
OK Proceed to next circuit inspection shown on
matrix chart (See page DI-396).
NG
Repair or replace harness or connector
(See page IN-36).
