U3017 Code - Control Module Timer/Clock Performance
Quick Answer
The Powertrain Control Module (PCM) determines that the ignition off time received from the Body Control Module (BCM) is either too high or too low compared to a calculated value. Common causes include Low Battery Charge, Reprogram Body Control Module (BCM), Faulty Body Control Module. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U3017 Description
The Diagnostic Trouble Code (DTC) will set when the BCM engine ignition off time is too high or low for the coolant temperature drop observed over the key cycle. The PCM will light the MIL lamp after this monitor runs and fails twice. The PCM will turn off the MIL lamp once the diagnostic runs and passes in four consecutive drive cycles. Note: This DTC can also set when using the scan tool to change the vehicle from Shipping Mode to Customer Mode (during New Vehicle Prep).
What are the Possible Causes of the DTC U3017?
- Low Battery Charge
- Reprogram Body Control Module (BCM)
- Faulty Body Control Module
- Body Control Module harness is open or shorted
- Body Control Module circuit poor electrical connection
