Stay ahead of the curve\u00a0with the latest Technical Service Bulletins (TSBs) added in the past two months.
\nDDTSB is growing again \u2013 this time with 221 brand-new TSBs and 130 updates, all based on real hotline cases and real-world diagnostics from workshops across Europe. Here are three strong, technically relevant examples from the new material.<\/p>\n
\u2705 PSA\/Opel\/Toyota BEV \u2013 Unable to enter READY mode, vehicle may shut down while driving (P0AA6, P0106A\/E)
\n(Citro\u00ebn e-Jumpy 2021 \u2013 11 kW OBC)
\nSymptoms & fault codes:
\n\u2022 No READY mode, vehicle may stall while driving
\n\u2022 Frequent HV-related trouble codes: P0AA6 09, P0106A 09, P0106E 09
\nDiagnosis in practice:
\n\u2022 Parameter readings showed very low insulation resistance on the negative HV circuit (~2345 k\u03a9), while the positive side was around 60,000 k\u03a9.
\n\u2022 A megger test at the HV battery connector showed faults on both conductors, but the real reason was an internal coupling via the inverter\/OBC, making it appear as if both sides were faulty.
\n\u2022 The actual fault was the HV cable between the inverter and onboard charger. The fault only appeared when the cable was physically moved \u2013 a classic pattern for internal cable wear.
