| DTC |
Description |
Possible causes |
Action |
| C1A0046 |
Control module |
- Incorrect car configuration file (CCF) data received from instrument
pack cluster (IPC) or CCF incorrectly configured.
- Modulator installed to unrecognized vehicle configuration
- Vehicle dynamics control module calibration/parameter memory failure
(internal error)
|
Configure the module using the approved diagnostic system.
Clear the DTC and check if the DTC resets after ignition reset following
>10 seconds ignition on. If the above is correct and the DTC persists,
renew the modulator. Refer to the warranty policy and procedures manual if
a module is suspect. |
