If the above procedures fail to diagnose the issue you may have a wiring fault. Unplug the
RJ45 from the PIDU+ and check the following resistances at the RJ45:
1. Check the cable resistance between pins 1 & 2, 3 & 6, 4 & 5 and 7 & 8 at the RJ45.
2. Check against column 2 in Table 23. Resistances for each pair should be within 1 ohm of
each other.
3. Check the cable resistance between pins 1 & 3 at the RJ45. Check against column 3 in
Table 23.
