Table 21. Diagnostic Fault Register: Channel 2 and 3

Diagnostic fault bit indicates short between loops, short to battery, open circuit, short to ground, high or

low side MOS fault. The channel number is determined by the address bit in register mode command.

These faults are decoded as shown in Diagnostic Fault-bit Definition table. Bit D7 and bit D3 indicate if a

fault condition exists in the respective channels. Loss of ground fault has the highest priority among all

fault conditions.
