C1A13 on Jaguar
ABS/Stability Control Communication Fault
C1A13 on Jaguar vehicles indicates abs/stability control communication fault. Au7o has documented this code across 1 Jaguar model — most commonly on XJ. C1A13 is a brake-system communication code indicating a fault in the data exchange between the ABS and the stability control (ESC/VSC) function. These systems share wheel speed, yaw, steering, and brake data over the vehicle's network to coordinate ABS, traction, and stability control. When expected messages are missing, corrupted, or delayed, the module flags a communication fault and typically disables stability/traction features. It generally points to a network (CAN bus) problem, a non-responding module, or wiring/power issues rather than a single mechanical part. Base braking remains, but the safety-control functions may be offline. Typical repair costs on Jaguar range from $1,000 to $3,000, depending on the specific model and root cause.
Common Causes of C1A13
- •CAN bus / communication wiring fault between modules
- •Unresponsive or failed ABS or stability control module
- •Low or unstable battery/system voltage
- •Corroded, loose, or damaged module connectors
- •Poor power or ground connection at a control module
- •Related sensor faults (yaw, steering angle, wheel speed) breaking data plausibility
- •Software mismatch after a module replacement without programming
C1A13 on Jaguar by Model
Jaguar XJ(1 issue)
- Air Suspension Compressor Failure2004-2019
The Dunlop or Hitachi air suspension compressor on the XJ fails due to overwork from leaking air springs or aging valve blocks. The compressor runs continuously, overheats, and eventually burns out. This is one of the most common and expensive repairs on the XJ.

What does C1A13 mean on Jaguar?▼
C1A13 stands for "ABS/Stability Control Communication Fault." C1A13 is a brake-system communication code indicating a fault in the data exchange between the ABS and the stability control (ESC/VSC) function. These systems share wheel speed, yaw, steering, and brake data over the vehicle's network to coordinate ABS, traction, and stability control. When expected messages are missing, corrupted, or delayed, the module flags a communication fault and typically disables stability/traction features. It generally points to a network (CAN bus) problem, a non-responding module, or wiring/power issues rather than a single mechanical part. Base braking remains, but the safety-control functions may be offline. On Jaguar specifically, this code is documented across 1 model.
What causes C1A13 on Jaguar vehicles?▼
Common causes on Jaguar: CAN bus / communication wiring fault between modules, Unresponsive or failed ABS or stability control module, Low or unstable battery/system voltage, Corroded, loose, or damaged module connectors, Poor power or ground connection at a control module. Specific causes vary by model and year — see the per-model sections below.
