Check the connections on the gauge cluster and at the ecu and check your grounds. Service manual says the ecu is getting faulty readings from the cluster.

Pretty sure i found the issue View attachment 1020706
This looks like improper routing over the radiator area. I had the same issue. Check all the harnesses that run through there and make sure they are routed per the manual routing diagram.

As for Er-4 still remaining, go ahead and check those other harnesses that run over the top of the radiator and inspect the connections behind the dash under the windscreen.
