DIAGNOSTICS ENGINE
1996 LAND CRUISER (RM451U)
INSPECTION PROCEDURE
1 Check for open and short in harness and connector between ECM and heated
oxygen sensor (bank 1 sensor 1) (See page IN−28 ).
NG Repair or replace harness or connector
(See page IN−28 ).
OK
2 Check for heated oxygen sensor (bank 1 sensor 1) data.
PREPARATION:
(a) Remove the fuse cover on the instrument panel.
(b) Connect the OBD II scan tool or TOYOTA hand−held tester to the DLC3.
(c) Warm up engine to normal operating temp.
CHECK:
Read the heated oxygen sensor (bank 1 sensor 1) output voltage and sho\
rt −term fuel trim.
RESULT:
PatternHeated o xygen sensor (bank 1 sensor 1) output voltageShort−term fuel trim
1Lean condition (Changes at 0.55 V or less)Changes at about +20 %
2Rich condition (Changes at 0.4 V or more)Changes at about −20 %
3Except 1 and 2
1, 2 Check fuel trim system (See page DI−51 ).

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.
