Customer Question

Hi. I have a Dodge Durango 5.7 with an ABS light on. I did a scan and I've got the code C121D ( Brake Pressure Sensor Circuit). Any ideas?
JA: Is it just the ABS light? Or is the brake system warning light on, too?
Customer: Only ABS and ESP
JA: What year is your Durango?
Customer: 2007
JA: Are you fixing your Durango yourself? What have you tried so far?
Customer: Yes. I am doing it by myself. I've already changed the ABS computer. I went to a dealer and he told me to do so.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I don't think so.

That's a pretty difficult question . I did it for a few months ago so , I don't remember .

Hi Lucian .

Okay they probably told you to replace the module as this is the most common issue for this code .

But should of been tested before doing this .

But you may find your problem is in fact the ICU Integrated control unit ..

After rating there is no further cost for any other question relating this issue .
Kind regards Greg
