- Inspect the foam seals for tears and leak paths, to ensure they will not compromise the internal air flow through the generator control module assembly.
- Install the generator control module (3) to the support tray studs. Tighten the fastener (1) to 9 N.m (80 lb in).
- Tighten the remaining fasteners (2) to 9 N.m (80 lb in).
- Place the drive motor battery wire junction block relay (2) and the battery energy control module wiring junction block (1), on top of the generator control module.
- Install the high voltage bus fasteners (1) to the drive motor battery wiring junction block relay assembly (2) and tighten to 9 N.m (80 lb in).
- Install the battery energy control module wiring junction block fasteners (1) and tighten to 9 N.m (80 lb in).
- Install the drive motor battery wiring junction block relay fasteners (3) and tighten to 9 N.m (80 lb in).
- Connect the generator control module X4 connector (1).
- Enable the high voltage at the A4 hybrid battery pack. Refer to High Voltage Enabling .
- Program the generator control module. Refer to Control Module References .
CAUTION:
Refer to Fastener Caution .
NOTE:
Do not slide the generator control module on the foam seals as the seals may become damaged.
NOTE:
Critical high voltage fastener. Perform second torque verification check following re-assembly.
