Service bulletin LI00.20-P-078424

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Complaint The remaining time shown on the instrument cluster in the workshop menu (days to next due service) is implausible (> < 365 days) for the following conditions: • for the date of the vehicle handover • or the last conducted and confirmed Service A/B Cause The following conditions can occur on vehicles with a disconnected on-board electrical system battery (12V/48V): • The period in which the on-board electrical system battery is disconnected cannot be counted by the maintenance computer. • As soon as the on-board electrical system battery is connected again, the maintenance computer automatically starts counting without making a correction to the remaining time (days to next due service). Remedy Allowance must be made for vehicles with disconnected on-board electrical system battery. The following process must be complied with to achieve a correct calculation: • (A): The number of days from the "day of vehicle handover or the last conducted Service A/B" onward up to the "day on which the vehicle arrived at the workshop". • (B): Remaining time (days to next due service date shown on instrument cluster). • (C): Days on which the on-board electrical system battery was disconnected. The formula requires the following condition to be complied with. 365 - (A) [days] = (B) - (C) [days] If the on-board electrical system battery (12 V/48 V) was not disconnected and the remaining time shown on the instrument cluster in the customer or workshop menu (days to next due service) is implausible with regard to the date of the vehicle handover or the last conducted and confirmed service A/B, or the condition in the formula was not complied with, the service can nevertheless be conducted and confirmed. A TIPS case should only be created if the vehicle is more than 90 days over the actual service due date. In these cases, attach the control unit logs from the instrument cluster, PTCU and electronic ignition lock as well as a quick test.
