Module Circuit Inspection

Power Circuit Inspection 

1. Ignition "OFF"
2. Refer to "HYBRID POWER CONTROL UNIT (HPCU) " and disconnect HPCU connector.
3. Ignition "ON"
4. Measure voltage between Pin No. 4, 5, 6 (Power) terminal of HPCU harness connector and chassis ground.
5. Measure voltage between Pin No. 34 (ON/Start Input) terminal of HPCU harness connector and chassis ground.

   Specification:  B+

6. Is measured value within specification?

   YES 

   • Go to "Ground Circuit Inspection" procedure below.

   NO 

   • Repair open or short in power circuit, and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Ground Circuit Inspection 

1. Ignition "OFF"
2. Disconnect Battery (-) terminal.
3. Refer to "HYBRID POWER CONTROL UNIT (HPCU) " and disconnect HPCU connector.
4. Measure resistance between Pin No. 1, 2, 3 (Ground) terminal of HPCU harness connector and chassis ground.

   Specification:  Approx. below 1Ω

5. Is measured value within specification?

   YES 

   • Go to "COMPONENT INSPECTION " procedure.

   NO 

   • Repair open or short in ground circuit, and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
