DTC Fault Code Index (Discovery 3)

NOTE: Universal Scan Tools cannot read the listed codes or can only read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the listed 7 digit code to identify the problem (the last 2 digits give additional information read by the diagnostic system approved by the manufacturer).

Also refer to section 206-09 "Anti-Lock Braking System - Traction Control System" in the workshop manual.

DTC	Description	Possible reasons	Action
C1A0046	control module	Incorrect vehicle configuration file data (CCF), received from instrument panel (IPC) or incorrect CCF configuration. Installed modulator does not match vehicle configuration Malfunction of memory of calibration/parameters of the module of control of stability of the car (Internal error)	Configure the module using an approved diagnostic system. Clear the DTC and check if a DTC is generated after the ignition has been reset after more than 10 seconds of ignition on. If the above is normal and the DTC persists, replace the modulator. If a module is suspected, refer to the warranty policy and procedures manual.
C1A0196	Light-emitting diode	LED Circuit Short to Ground high resistance	Check LED and electrical circuits. Refer to the electrical manual.
C1A0294	Angle encoder stuck in middle position	Detected that the rotary switch has been between detents for more than 1 minute	Check the operation of the rotary switch.
