Hi guys, I brought my car into the shop today to get the shake in my shearing wheel looked at, at a code U1B01 came up. Its a body control module code but they did not know what it meant. shocks and suspension look all good and tight and i have brand new rims on the car.

The shake was there when I have my stock tires on and also my old 20" so I am pretty sure it is no a suspension or balance issue.

Any idea what the code is for, I cant find any referrence on it?

according to the Helm manual DTC codes do not have another letter after the first one. Is the code possibly U1301 instead of U1B01

that could be possible, put I had him write it down twice and he put a B. What is U1301 mean?

Here are a few in that range and the link below to the 45 pages of codes.

• U1300 - Class 2 Short to Ground
• U1301 - Class 2 Short to Battery
• U1304 - Loss Of UART Communications
