It covers how the system works, common failures and a few troubleshooting tips. School is in session! For a visual reference, refer to Robert Bentley Manual page 97.163 & 97.164 for the circuit diagram of this system. The power door locks on Eurovans and Vanagons are exactly the same and, in fact, use the same actuators.
