Need help finding terminal 31 on relay block

[Luckyman01]

In the Bentley book, page 24-7 Fuel injection, DME Component testing, one of the tests is check for continuity at terminal 31 on relay block.

I cannot find terminal 31.

Can anyone help?

I think that may be a misprint. Terminal 85 on the relay/block is the ground for that circuit. Can’t locate a 31 in the diagram.

Couldn’t hurt to trace that ground to GP8.

I could not find 31 in another documentation either.

I will reverify the ground on that circuit.

It may not exactly answer your question, but on these German cars there is standard terminology for certain circuits. Terminal 31 refers to ground, Terminal 30 is +12V hot at all times, terminal 15 is switched +12V, etc... *So, you are looking for continuity to ground I expect.
