Error in CRC computation for Message, VehicleData
â–¶ How to fix
Step-1: Check the sending ECU(s). Step-2: Check the CAN connection.
What you'll see
The driver might detect reduction in Assistance/Hard Steering due to reduced electrical support.
System reaction
The substitute vehicle speed of 90 Kmph is used when this CAN message error detected.
Diagnostic depth
Detection
1. Invalid data received with message, VehicleData. 2. Invalid message identifier received with message, VehicleData. 3. The DTC will set during the following condition: 1.system state: NMWait, PreDrive, DriveDown, DriveUp, PostRun, Off, Error, Flash, LowVolt. 2.system voltage is above 16v. 3.system voltage is below 32v.
Possible cause
1. Data loss during CAN Bus data transmission. 2. Incorrect CRC calculation by the VehicleData message sending ECU.
