Serial Peripheral Interface (SPI) serial data bus to override its normal operation and force the Instrument Cluster to enable its outputs (gauges move,
indicators lit etc). This mode can be used to determine whether the Instrument Cluster is capable of producing a given output. The outputs that can be
controlled are listed in TABLE #11.
