Damage code:	Cause:	Remedy:
	A hardware fault in the tire pressure monitoring system (TMP [RDK] may impair CAN-B operation.	If you can confirm the named symptoms / notes: ↓
	Impaired CAN-B operation results in malfunctions in the instrument cluster and display instruments (e.g. jumps in fuel level or temperature indicator). Various warning and fault lamps go on and off in cycles. Exterior lights switch on and off without obvious cause. In addition, depending on the duration of the malfunction, fault codes (CAN communication disturbance) may be stored in the various control modules linked to CAN-B (such as the TPM [RDK], signal acquisition and actuation module (SAM), electronic ignition switch (EIS [EZS]), lower control panel (LCP [UBF]), vehicle power supply control module [BNS], roll bar soft top control module [UVS], automatic air conditioning (AAC [KLA]), instrument cluster with maintenance interval display [KIW], etc.).	1 Remove/install/replace TPM [RDK] control module
