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.

1 Check fuel pump operation (See page SF-7).
OK Go to step 8.
NG
2 Connect hand-held tester, and check operation of fuel pump relay.
PREPARATION:
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tester main switch ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / FUEL PUMP / SPD.
