C0244 code meaning
PWM Brake Pressure Modulation Circuit
What C0244 means
No public J2012 table carries C0244, and no maker documents a meaning matching the title. The only public use is Saab's, and it concerns the engine torque signal. On the 1998 9-5 with TC/ABS 5.3 the Trionic engine module reports actual torque to the brake module as a pulse-width signal; C0244 is stored when that line is open or shorted. On the 2004 9-5 with ESP the torque value arrives over the data bus, and C0244 means the engine module flagged its own value as invalid. Either way the TCS or ESP OFF lamp comes on and the function is lost, while ABS keeps working. The pulse-width idea in the title fits this signal, not a brake pressure valve. Diagnosis starts in the engine module; the current torque can be read with a scan tool.
C0244 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0244
- TCS OFF or ESP OFF lamp on
- No traction or stability control, ABS still active
Common causes of C0244
- Most likelyOpen or shorted torque signal line between engine and brake module (Saab 9-5 1998)
- Most likelyFault in the engine control module that invalidates the torque value
- Less likelyData bus problem between engine and brake module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C0244 means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 44 | The exact fault in that area. |
What to do next
- Note C0244 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 C0244
What does C0244 mean?
C0244 means "PWM Brake Pressure Modulation Circuit". No public J2012 table carries C0244, and no maker documents a meaning matching the title. It is a generic code, so it means the same on every make.
Is it safe to drive with C0244?
Drive gently and only to a workshop. With C0244 the car can go into limp mode (reduced power) to protect itself.
Will C0244 fail an emissions test?
C0244 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 C0244 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will C0244 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
