When you replaced the access modules did you have to do anything with the software? Something could have been turned off when you flashed the software and it is now not talking.

Access2 pin 18 to pin 19 should be 120 ohm

Ok, we checked both access 1 and 3 on the specified pins and they read at 120 ohm.

Unplug the connectors from Access1 and Access3. Pin 18 to pin 19 on Access1 (not the wire) should be 120 ohm. And on Access3, pin 17 to pin 19 should be 120 ohm. If either is lower than 115 ohm or greater than 125 ohm......replace that Access module. Sometimes I forget, even though a part is new...doesn't mean it's good.

Sorry, when they are plugged in we are getting 59.6 ohms. When the can line is unplugged for the test we are getting 120. Event code 112 still happening.

If you got 120 ohms on the CAN line with all the modules plugged in then you have a problem. It should only be 60 ohms

Fact of the week
In the 1840's Valentine Day cards were popular. But a new trend developed where cynical, sarcastic, often mean-spirited cards were produced to be sent to people you disliked. 'Vinegar valentines' were postcards decorated with a mocking caricature and insulting poem. The unflattering cards reportedly created a stir throughout all social levels.
