When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Customers of 2004 SRX vehicles may have a condition of an amber traction off lamp and/or amber ABS lamp illuminated, with codes C0220 (left front release too long). C0221 ( right front release too long), and C0228 (left rear release too long). The code will only set after the vehicle is first started, moved slightly, then let set for some time between 10 seconds and several minutes with the brake released. When the driver places their foot back on the brake pedal, they may experience a hard brake pedal, then a sudden drop to normal level after the codes set.

New ABS software is available through the dealer TIS software version 2.0 or newer. Install the updated ABS software to correct this condition.
