2 Check PATTERN SEL SW signal.
When using TOYOTA hand −held tester:
PREPARATION:
(a) Remove the fuse box cover.
(b) Connect a TOYOTA hand−held tester to the DLC3.
(c) Turn the ignition switch ON and TOYOTA hand−held tes-
ter main switch ON.
CHECK:
Read the PWR signal on the TOYOTA hand −held tester.
OK:

When not using TOYOTA hand −held tester:
PREPARATION:
Turn the ignition switch ON.
CHECK:
Measure the voltage between terminal PWR of the ECM con-
nector and body ground when the PWR mode switch is set to
the PWR (POWER) position and NORM (NORMAL) position.
OK:
PWR Mode SwitchVoltage
PWR7.5 − 14 V
NORMBelow 1.5 V
HINT:
The ECM uses the normal pattern signal if the power signal is
not input.
OK Proceed to next circuit inspection shown on problem symptoms table (See page DI−147 ).
