2013 Grand Caravan No Crank: TIPM Diagnosis and Follow-Up

TIPM Replacement and Initial Checks

• 💡 A 2013 Grand Caravan that previously had a 'no crank' issue is revisited after a temporary bypass was implemented.
• 🛠️ The team is installing a new, used TIPM (Totally Integrated Power Module) to resolve the original problem.
• 🔍 Before removal, connectors are inspected, and the fuse destinations are compared to the new TIPM, noting a missing 10-amp fuse for the collision high-mounted stop lamp (M1).

TIPM Installation and Verification

• ⚙️ The original TIPM, part number 68163904AC, is removed after disconnecting the battery.
• ✅ The new TIPM is installed, ensuring all connectors are properly seated and the Christmas tree fastener is secured.
• 🚀 The vehicle is tested, and it successfully cranks, confirming the initial diagnosis and the effectiveness of the TIPM replacement.

TIPM Configuration and Scan Tool Limitations

• 🔑 It's noted that TIPMs can only have the VIN programmed twice before requiring a special program to erase the VIN.
• 💻 The scan tool indicates the new TIPM was virgin or had the correct VIN programmed, as the old VIN was visible before the new one was applied.
• ⚠️ The current scan tools (AlteL and Launch) lack the specific 'configuration restore' function needed to match the TIPM options to the vehicle's VIN, unlike Chrysler's proprietary WiTech system.
• 📈 While these tools can add sales codes (e.g., turning on a third-row DVD option), they cannot perform the full configuration restore.

Conclusion and Customer Handover

• 👍 The temporary bypass worked, and the customer has been satisfied with the vehicle's functionality.
• 🤝 The vehicle is returned to the customer, with the understanding that the new TIPM installation is a more permanent solution.
• 💬 The video serves as a follow-up to provide closure and confirm the correct diagnosis, despite the initial temporary fix.
