DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 10 V or more at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-386, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK BATTERY TEMPERATURE SENSOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK BATTERY TEMPERATURE SENSOR POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK BATTERY TEMPERATURE SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK BATTERY TEMPERATURE SENSOR
Check the battery temperature sensor. Refer to EC-387, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace battery negative cable assembly.
Component Inspection
1.CHECK BATTERY TEMPERATURE SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace battery negative cable assembly.
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 ...
Intermittent Incident
DESCRIPTION
Sometimes the symptom is not present when the vehicle is brought in for
service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No
Trouble Found Diagnosis. The fol-
lowing section illustrates ways to simulate the conditions/env ...
