P0D1F Control Module Date/Time Synchronization Error

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P0D1F says a control module could not align its internal date and time with the reference the rest of the vehicle uses. Hybrid modules need a trustworthy clock because several checks depend on how long the car has been parked: CARB, for example, ties cold-start monitoring to at least six hours off, and GM separately checks its module power-off timer against the on-timer (P262B, more than 5.6 % deviation on the 2012 Volt). Volvo stores P0D1F62 in the BECM of its long-range plug-in hybrids from 2022 to 2024 with the check engine light on. Journals TJ 36681 and TJ 36707 call it a misdetection, rule out parts replacement and prescribe BECM software 2.11. If P0D1F96 follows the update, the car must sleep at least 15 minutes to resync its timers before the code is erased.

Likely causes

Module software misdetecting the time comparison (Volvo BECM software 2.11)
Timers not yet resynchronised after programming because the car has not slept
Missing or wrong time information from the module providing the reference clock

Symptoms

  • Check engine light without a noticeable driving fault
  • Code returns as a variant after a software update until the car has slept
