"Plant Mode Activated" Message and ABS Module Replacement

One significant TSB, identified as TSB 08-068-25, addresses the "Plant Mode Activated" message appearing in 2023-2025 Jeep Compass, Commander, Renegade, and 2024 RAM Rampage vehicles. This issue is often accompanied by a Malfunction Indicator Lamp (MIL) illumination, an ABS warning light, and various Diagnostic Trouble Codes (DTCs). Specifically, owners might encounter codes such as C170C-00, C1436-86, and C10D0.

The bulletin outlines a repair procedure that involves replacing the Anti-lock Brake System (ABS) module. This is a crucial fix as the ABS system is vital for vehicle safety and stability. Owners experiencing these symptoms should have their vehicle inspected promptly.

Widespread Adaptive Cruise Control (ACC) Faults in Jeep Compass

A recurring theme across multiple TSBs concerns the Adaptive Cruise Control (ACC) system in the Jeep Compass. Several bulletins, including TSB 08-160-26 for the 2023 model year, address the Jeep Compass ACC fault. Owners may observe a Malfunction Indicator Lamp (MIL) and the dashboard message "ACC/FCW Unavailable, Service Required." The common DTC associated with this issue is C14A4-00.

Similar bulletins were issued for other model years, including TSB 08-162-26 for 2025 models, TSB 08-161-26 and TSB 08-155-26 for 2024 models, TSB 08-159-26 and TSB 08-157-26 for 2022 models, TSB 08-158-26 for 2026 models, and TSB 08-156-26 for 2023 models. In most cases, the resolution involves updating the ACC module software. This software update aims to correct the underlying issue causing the ACC/FCW system to become unavailable.

Misfire DTCs, Rough Idle, and Valvetrain Noise

An important manufacturer communication, TSB 9100498 Rev 3, addresses engine performance issues such as misfire Diagnostic Trouble Codes (DTCs), rough idle, and valvetrain noise. This bulletin applies to a broad range of 2021-2025 Jeep, Dodge, and RAM vehicles. The root cause is often related to the oil pump operation mode.

The recommended fix for these engine concerns is a calibration or software update for the oil pump operation. This update helps ensure proper engine lubrication and can resolve the misfire and rough idle conditions. Owners experiencing these symptoms should consult their dealer for the necessary software update.

2025 Jeep Wrangler MIL Illumination and Multiple DTCs

For the 2025 Jeep Wrangler, TSB 23-019-25 addresses Malfunction Indicator Lamp (MIL) illumination along with various Diagnostic Trouble Codes (DTCs). These include P0133, P0607, and U0109, among others. The TSB also covers several other customer-reported symptoms, indicating a broader diagnostic approach for the 2025 Wrangler.

What Jeep owners should do

1. Monitor for Warning Messages: Pay close attention to any dashboard warning lights, especially the Malfunction Indicator Lamp (MIL) or ABS warning light. Also, take note of specific messages like "Plant Mode Activated" or "ACC/FCW Unavailable, Service Required."
2. Address ACC/FCW Issues: If your Jeep Compass displays the "ACC/FCW Unavailable, Service Required" message or exhibits a Jeep Compass ACC fault, contact your dealership. A software update for the Adaptive Cruise Control module is likely needed to resolve the issue.
3. Report Engine Performance Problems: If your 2021-2025 Jeep, Dodge, or RAM vehicle experiences misfire DTCs, a rough idle, or unusual valvetrain noise, schedule service. A software update for the oil pump operation may be required.
4. Consult Your Dealer: For any of the issues described in these service bulletins, or if you encounter other unexpected vehicle behavior, it is always best to consult an authorized Jeep service center. They can perform diagnostics and apply the appropriate TSB-recommended fixes.
