Driving Pattern
When the HDS is used:
- Connect the HDS, and start the engine.
- Remove the IPU lid.
- Request the battery module fan drive on the HDS.
- Verify that the battery module fan is actually running.
When the HDS is not used:
- Remove the IPU lid.
- Reset the BCM. (Disconnect the 12 V battery terminal once and reconnect it.)
- Remove the No. 15 EPS (40 A) fuse from the under-hood fuse/relay box.
- Hold the engine at a speed between 3,500 - 4,000 rpm without load (in Park or neutral), and wait until 19 segments of the indicator on the IMA battery charge gauge are indicated.
- Turn off the ignition switch.
- Repeat steps 2 - 5 five times. (Increase the battery module temperature.)
- Verify that the battery module fan drive is running when the engine is idling.
- Reinstall the No. 15 EPS (40 A) fuse and IPU lid.
