What P0D1F means
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.
P0D1F at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D1F
- Check engine light without a noticeable driving fault
- Code returns as a variant after a software update until the car has slept
Common causes of P0D1F
- Most likelyModule software misdetecting the time comparison (Volvo BECM software 2.11)
- PossibleTimers not yet resynchronised after programming because the car has not slept
- Less likelyMissing or wrong time information from the module providing the reference clock
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D1F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 1F | The exact fault in that area. |
What to do next
- Note P0D1F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D1F
What does P0D1F mean?
P0D1F means "Control Module Date/Time Synchronization Error". P0D1F says a control module could not align its internal date and time with the reference the rest of the vehicle uses. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D1F?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0D1F fail an emissions test?
P0D1F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0D1F to fix?
Difficulty: workshop only. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will P0D1F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
