Hej Skriveren,
Jeg har ingen viden om din årgang V70, men når jeg leder efter de fejlmeddelelser du nævner finder jeg forklaringerne nedenunder..
Det er skrevet i 'elektronik-latin', men fortæller en gammel elektronikingeniør at der er noget galt med kommunikationen på LIN-bussen.
Det kan være forårsaget af et kortsluttet eller afbrudt kabel.
Jeg ville undersøge det kabel der forbinder det berørte panel med omverden.
Det er så meget jeg kan hjælpe.

Volvo DTC CEM-B113087
Make: Volvo
Code: CEM-B113087
Definition: Light switch module. Bus Signal/Message Failures. Missing message
Description:
The Central Electronic Module (CEM) both transmits and receives information via a standardised serial communication method - LIN (Local Interconnect Network). The diagnostic trouble code (DTC) is stored if the control module detects that: If the control module registers a serious malfunction, e. g. , that LIN-communication to Light switch module (LSM) is blocked, the diagnostic trouble code is generated. The control module's test for the diagnostic trouble code (DTC) starts in the event of: Ignition switch position I and II. Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
Cause:
Short-circuit between the LIN wiring.
Open-circuit in the LIN wiring.
Internal fault in another unit in the same part of the LIN network.

Volvo DTC CEM-U030141
Make: Volvo
Code: CEM-U030141
Definition: CEM Software Incompatibility with ECM/PCM. System Internal Failures
Description:
The central electronic module (CEM) checks the software in the engine control module (ECM). At each start up, the control module checks the stored check sum against a calculated check sum. The diagnostic trouble code (DTC) is stored if the control module detects that: An internal check sum in the control module is invalid. The control module's test for the diagnostic trouble code (DTC) starts in the event of: Start-up of the control module. Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
Cause:
Incorrect software check sum.
