DTC U1016: Pcm Class 2 Source Id 10: Description

BCM receives a state of health message from each module whose source ID it has learned. DTC U1016 will set when BCM does not receive a state of health message from Powertrain Control Module (PCM) after it has received other messages from PCM. No driver warning message will be displayed.

A current DTC U1016 will change to a history code when BCM receives a state of health message from PCM. If conditions for malfunction no longer exist, history DTC will clear after 100 consecutive ignition cycles. DTC U1016 will also clear when scan tool is used to clear codes.

NOTE: When ignition switch is turned to RUN position with BCM disconnected, PCM-related DTC P1626 will be set. After BCM repair is completed, see appropriate TESTS W/CODES article in ENGINE PERFORMANCE section:
