C2200: Anti-lock brake module internal fault (Ram, Dodge)

ABS module internal fault

Severity: Inspect soon

FCA ties C2200 to the ABS light, which means anti-lock braking is not working; normal brakes still work but need service as soon as possible.

It gets more serious if:

Stop: Stop and have it checked immediately if the red brake warning light is on.

C2200 in short

On Ram and Dodge trucks, C2200 means the anti-lock brake module found a fault inside itself, often in its software. FCA bulletins fix some cases with a software update. Normal brakes keep working, but anti-lock may not; have it serviced soon, and stop if the red brake light is on.

The ABS module runs self-checks on its own hardware and software. C2200 is set when one of those checks fails. On the 2019 Ram 1500, FCA lists subcode -48, a supervision software failure.

A 2009 Chrysler bulletin says C2200 on about 125,000 Dodge Ram trucks with stability control could turn on the ABS, ESP or base brake warning lamps, and dealers fixed it by reflashing the ABS module. That makes a software update the first thing to ask about.

Owners of other FCA vehicles, such as the Jeep Wrangler, also report this code, but we found no bulletin that defines it for them. A dealer scan tool will show the exact subcode.

Pick your make

C2200 is a manufacturer-specific code: its meaning depends on who built the car.

Other makes: meaning not verified. Check with a scan tool that reads manufacturer definitions.

Cause 2: ABS module internal hardware failure
Possible — needs testing
Why it ranks here
The code itself names an internal module fault. If a software update does not clear it, the module may need replacing, but we found no bulletin that says how often.
What would change this
Rises if C2200 returns after the latest software is installed.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

Step 1: Note which warning lights are on: ABS, ESC or ESP, and the red brake light.
Low risk
- IfThe red brake warning light is on
  It meansFCA says part of the brake system may have failed. Do not keep driving.
  Go to step 3
- IfOnly the ABS or stability lights are on
  It meansNormal brakes should work, but anti-lock may not. Have it serviced soon.
  Go to step 2
Step 2: Have the codes read with a scan tool that reads FCA ABS codes, and note the subcode (for example -48).
Low riskTool: scan tool that reads FCA chassis codes
- IfC2200-48 on a 2019 Ram 1500, or C2200 on a 2009 Dodge Ram with ESP
  It meansThis matches an FCA software bulletin.
  Points to: ABS module software fault that needs an update
- IfAnother vehicle or subcode
  It meansAsk the dealer to check for any ABS module software updates.
  Go to step 3
Step 3: Have a dealer check for ABS module software updates and bulletins for the VIN, update the module, and retest.

- IfThe code clears after the update and does not return
  It meansThe software fault is fixed.
  Points to: ABS module software fault that needs an update
- IfThe code returns with the latest software
  It meansThe module itself may have failed.
  Points to: ABS module internal hardware failure

Symptoms

ABS warning light on
ESC or ESP light on
Red brake warning light on Gets more serious: stop and have it checked.
