is there an error if the upstream circuit breaker is 16A TP and the downstream circuit breaker is 16A TPN?
The difference between 16A TP and 16A TPN isolator is the type of the circuit breaker that is used. The terminal design is the other difference.

The quickest & easiest way to test a relay is by substitution. It can be bench tested using wires and a test lamp.
The LCM of 5a and 16a is 80a
Swap the relay with another like relay.
2 x 2 x 2 x 2 x A = 16A
To test a power steering relay, first locate the relay in the vehicle's fuse box or relay panel. Use a multimeter to check for continuity by removing the relay and testing the terminals; there should be continuity when the relay is energized. You can also swap the relay with a known good one to see if the power steering system starts functioning. If the relay fails the continuity test or the swap does not resolve the issue, it may need to be replaced.
18a2 + 16a + 38 = 3(6a2 + 8a + 19)
3a2+16a+5 = (3a+1)(a+5) when factored
A car relay is a remote control switch that controls electrical components. To see how you should test yours, check your owners manual. Simply swap it with another like relay.
To test the main relay in a 2004 Acura MDX, first locate the relay in the under-hood fuse box. Remove the relay and use a multimeter to check for continuity between the terminals; it should show continuity when activated. Additionally, you can apply 12 volts directly to the relay terminals to see if it clicks and operates properly. If it fails either test, replace the relay.
