The Gen III LS engine is managed by a separate ECU based on the [https://en.wikipedia.org/wiki/Motorola_68000 Motorola 68332] 32-bit microcontroller. On VT/VX/VY/VZ Commodores, this ECU integrates with the original 3800 PCM via a separate module, the '''Power-train Interface Module''' or '''PIM'''. Since the Gen III ECU only communicates via CAN bus, the PIM is needed to translate CAN messages into ALDL messages, and vice-versa. The original 3800 PCM is retained for control of the 4L60-E automatic transmission, however engine management functions are disabled via software configuration. Scan tools and other diagnostic equipment communicate with the Gen III ECU directly over CAN bus (exposed on the OBD port using pins 6 and 14).
