INSPECTION PROCEDURE

1. INSPECT HYBRID VEHICLE CONTROL ECU

1. Connect the intelligent tester to the HV control ECU terminals specified in the table below and check the waveform.

   Item	Contents
   Terminal	ABFS (H29-8) - E1 (H32-5)
   Equipment Setting	5 V/DIV, 500 ms/DIV
   Condition	READY-on state

   OK:

   The waveform appears as shown in the illustration.
   

NG	Go to step 3

OK

2. CHECK FOR INTERMITTENT PROBLEMS

NEXT

3. CHECK HYBRID VEHICLE CONTROL ECU

1. Turn the ignition switch off.

2. Disconnect the all connectors from the HV control ECU.

3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance:

   Tester Connection	Specified Condition
   ABFS (H29-8) - +B (H31-2)	13k to 17 kΩ at 20°C (68°F)

NG	REPLACE HYBRID VEHICLE CONTROL ECU

OK

4. CHECK HARNESS AND CONNECTOR (HV CONTROL ECU - AIRBAG SENSOR ASSEMBLY CENTER)

1. Turn the ignition switch off.

2. Connect the H29 connector to the HV control ECU.

3. Disconnect the A24 connector from the airbag sensor assembly center.

4. Measure the voltage according to the value(s) in the table below when the ignition switch is in the ON position.

   Standard Voltage:

   Tester Connection	Specified Condition
   ABFS (H29-8) - Body ground	Below 1 V

5. Turn the ignition switch off.

6. Measure the resistance according to the value(s) in the table below.

   Standard Resistance:

   Tester Connection	Standard:
   ABFS (H29-8) - GSW2 (A24-25)	Below 1 Ω

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
REPLACE AIR BAG SENSOR ASSEMBLY CENTER
