1996 LAND CRUISER (RM451U)
Pattern Select Switch Circuit (PWR Mode Switch)
CIRCUIT DESCRIPTION
The ECM memory contains the shift programs for the NORMAL and POWER pattern\
s, 2 position, L position
and the lock −up patterns. Following the programs corresponding to the signals from th\
e pattern select
switch, the park/neutral position switch and other various sensors, the ECM swi\
tches the solenoid valves
ON and OFF, and control the transmission gear change and the lock −up clutch operation.

INSPECTION PROCEDURE
1 Check operation of PWR indicator light.
PREPARATION:
Check if the PWR indicator light normally when the PWR mode switch is set to NORM and PWR position.
NG Check and repair PWR indicator light.

DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
When removing the part, turn the ignition switch OFF.
HINT:
Using SST 09843 −18020, connect the terminals Tc and E1, and remove the short pin.
If any abnormality is not found when inspection parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circu\
it listed that the code. For details
of each code, turn to the page referred to under the ”See page” for respective ”DTC N\
o.” in the DTC chart.
