The owner of this 2010 Acura MDX has been waiting for a month for me to make the trip and diagnose his unpredictable 2010 Acura MDX that intermittently refuses to fire up.

The green "Immobilizer" key blinks on the dash when the car is acting up, setting a mysterious "D-2" fault in memory.

This was a tough diagnosis due to the intermittent nature of the problem.
You will NEVER guess what the problem is!
