NO >> Repair or replace error-detected parts.
5.CHECK APP SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK APP SENSOR INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 7.
NO >> Repair or replace error-detected parts
7.CHECK APP SENSOR
Check APP sensor. Refer to EC-443, "Component Inspection (APP Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace accelerator pedal assembly. Refer to ACC-3, "Removal and Installation".
Component Inspection (APP Sensor)
1.CHECK ACCELERATOR PEDAL POSITION SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace accelerator pedal assembly. Refer to ACC-3, "Removal and Installation".
Headlamp (lo) circuit
Description
The ipdm e/r (intelligent power distribution module engine room) controls the
headlamp low relay based on
inputs from the bcm over the can communication lines. When the headlamp low
relay is energized, power
flows through fuses 43 and 44, located in the ipdm e/r. Power then flows ...

Diagnosis Procedure
NOTE:
If low tire pressure warning lamp repeats blinking ON for 2 seconds and
OFF for 0.2 seconds, wake-up operation
for all transmitters is not complete.
Carry out transmitter wake-up operation. Refer to WT-22, "Work Procedure".
1.CHECK BCM CONNECTOR
