What P2C98 means
P2C98 flags a battery disable line whose level is above the permitted range, usually through a short to 12 V or a sender that drives the line too high. Unlike the low case, the risk here can be hidden: if a high level means all clear, a stuck-high line would no longer pass on a real shutdown request. That is the point of such a wire in Volkswagen patent US9586481B2, which lets a crash signal open the contactor within 10–100 ms, and in Coda patent US20110304202A1, which disconnects the battery once airbag deployment is decided. The controller therefore flags the line even while driving seems normal; the CAN path normally remains as a backup. No manufacturer documents P2C98 publicly. CARB requires monitoring of hybrid components. Inspect the line for contact with feed wires.
P2C98 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C98
- High-voltage system warning, often without noticeable driving fault
- Ready mode may be blocked after the next restart, depending on maker
Common causes of P2C98
- Most likelyDisable line shorted to 12 V supply
- PossibleSending module driving the line above the valid level
- Less likelyInput stage in the battery controller misreading the level
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C98 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 98 | The exact fault in that area. |
What to do next
- Note P2C98 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 P2C98
What does P2C98 mean?
P2C98 means "Hybrid/EV Battery Disable Circuit High". P2C98 flags a battery disable line whose level is above the permitted range, usually through a short to 12 V or a sender that drives the line too high. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C98?
Drive gently and only to a workshop. With P2C98 the car can go into limp mode (reduced power) to protect itself.
Will P2C98 fail an emissions test?
P2C98 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 P2C98 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2C98 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
