Vehicle does not start, battery discharged. Topic number LI54.10-P-066341 Version 3 Function group 54.10 Battery, power supply, voltage converter Date 08-08-2017 Validity BR231 and BR172 Reason for change Examples added Reason for block Complaint: Vehicle does not start, battery discharged. The on-board electrical system data indicates a high discharge in the engine-off cycle; "CAN bus awake unusually long", "Charge balance UNUSUAL" Attachments File Description Beispiel_Buswachhalter.pdf Example_bus keepawake control unit example_BUS_keep_awake.pdf Example_BUS_keep_awake Cause: To be able to assess whether a bus keepawake event caused the battery discharge, it is necessary to examine the stationary cycles. A constantly active CAN is identified by the text "Interior CAN awake unusually long" (see attachment). If this text is not displayed, the battery discharge has a different cause. Cause 1: IC (instrument cluster) is keeping the CAN bus awake. Vehicle battery is being discharged. Affects vehicles with code 807 (Model Year 2017). Fault identification: 1. Affects vehicles as of code 807. 2. The on-board electrical system data indicates a high discharge in the engine-off cycle; "CAN bus awake unusually long", "Charge balance UNUSUAL" 3. The bus keepawake entry names the IC NOTE: See examples in attachments below Cause 2: HERMES is keeping the CAN bus awake, only affects USA (code 494).

This complaint can only be resolved by a software update. Remedy (with Clean Point) to be published per TIPS. Please open a PTSS Case including documentation described in Remedy 3 below. Damage code: 54201-54 Remedy 2: Refer to LI82.85-P-066086. Damage code: 8209Z-90 "Remedy" 3: **If not identified in Cause 1 or 2, please create a PTSS case with all the documents listed below and include in the case attachments.** Engineering may provide further instruction upon reviewing each case. Documents needed in case attachments: 1. Quick test 2. Control units event log for signal acquisition and actuation module (SAM) 3. Bus keepawake event detection (from EIS --> Actual values) 3.1. Last bus keepawake entry 3.2. Last-but-one bus keepawake entry 4. Up-to-date quiescent current measurement.
