Jeep Dual Battery Replacement (2018–2023 Gladiator JT & Wrangler JL) | ESS Aux Battery + IBS Reset

Описание: If you’re searching for a Jeep Gladiator dual battery replacement, Jeep Wrangler JL ESS battery replacement, or trying to locate the auxiliary AGM battery on a 3.6L Pentastar, this livestream walks you through the full repair from start to finish. I’m replacing both AGM batteries on a 2020 Jeep Gladiator JT equipped with Engine Start/Stop and performing the proper IBS reset using a professional scan tool.

These 2018–2023 Wrangler JL and 2020–2023 Gladiator JT models use a dual AGM battery system — a main Group 94R (H7) battery and a smaller AUX14 auxiliary ESS battery mounted beneath the tray area. When the auxiliary battery fails, it can cause start/stop warnings, low voltage communication codes, electrical instability, premature main battery failure, and even no-shift conditions out of park.

This is real-world mobile mechanic life, showing professional-level diagnostics that DIY mechanics and shop techs can follow step by step.

This procedure applies to:
• 2020–2023 Jeep Gladiator JT 3.6L with ESS
• 2018–2023 Jeep Wrangler JL 3.6L with ESS
• Chrysler / Dodge / Ram ESS vehicles using dual AGM systems

In this live repair I show:
• Proper cable disconnect order
• Auxiliary battery access methods
• Correct AGM battery specifications
• Safe reconnect sequence
• Battery Monitoring / IBS reset using Autel MaxiIM IM608 PRO II
• Clearing ESS and low-voltage related fault codes

No dealership fluff — just real mechanic life diagnostics done right.
