# Service bulletin 9100833

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 11034342
- Published by NHTSA: 2026\-07\-02

- NHTSA component: FUEL/PROPULSION SYSTEM

## NHTSA's summary

Fuel Delivery Module Before replacing the fuel module for DTCs P0461 and P062A and other not start, long crank, fuel gauge accuracy and drivability issues, the technician should disconnect the electrical connector at the pump and perform a visual inspection of the connector for and bent, spread, or pushed out terminals. Repair any issues found. Reconnect the plug and perform a push pull push to ensure the connector is fully installed. Then perform 3 keys cycles and listen to hear if the fuel pump is operational. If the fuel pump is heard that indicates that everything is operating correctly. If the pump is heard replacement is not necessary, any replacement will function in the same way.

Incorrect Fuel Tank Installed Customers must experience a Malfunction Indicator Lamp \(MIL\) illumination and the vehicle must SYMPTOM: exhibit/set the following Diagnostic Trouble Code \(DTC\): ● P062A\-00 \- Fuel Pump "A" Control Circuit Range/Performance. No customer facing symptoms are reported other than the MIL illumination. This bulletin involves inspecting the fuel tank part number and possibly replacing the fuel pump assembly.

- [9100840](/bulletins/11035192.md), 2026-07-23, Service bulletin: FUEL/PROPULSION SYSTEM. Switchbank 4 gang The customer will notice either one or two of the following conditions: 1. Fuel Door is Not opening when Fuel door Switch is pushed. Technician Observe the DTC P04CB\-FUEL FILL DOOR OPEN REQUEST SENSOR\-SWITCH CIRCUIT HIGH. 2. Drives Modes do not work when Switch is pressed \(Hybrid, Electric, E\-save\). Technician Observe DTC U113B\-LOST COMMUNICATION WITH SWITCH BANK MODULE. Procedure: If during vehicle Scan diagnostics besides DTC's P04CA, P04CB or U113B. there are another DTCs Repair it First accordingly. DTC's may be related to main ECU's like: HCP, BCM, PCM, etc. If DTC P04CB and/or U113B are still present, then follow the following action before replacing the Switch: 1. Read vehicle DTCs while the IGN ON. 2. Verify ESBM feed fuse state. Replace the fuse if needed. 3. Wiggle the ESBM harness takeout \(LIN and ESBM feed takeout\) and monitor the state of DTC P04CB and/or U113B. o If this step affects DTC P04CB and/or U113B. behavior, the issue is likely related to a failure in the harness. 4. Disconnect the harness from the ESBM and confirm there not any damage, like bend PINs, corrosion, etc. 5. Confirm Harness continuity. 6. Verify power to ESBM by back probing the ESBM connector o If voltage is lower than 11.8V, follow normal procedures for low batteries. \- If there no damage in the harness nor the connector and pins of the ESBM, reconnect it ensuring the harness connector is being fully engaged into the ESBM connector. 7. Confirm Continuity of the harness from the ESBM connector to the BCM connectors. 8. Reconnect the ESBM and then Verify LIN bus activity with Mopar scope. o Config scope to LIN monitor if feasible. o Replace the ESBM only based confirmation from the LIN diagnostic. 9. With the scan tool, read DTCs. If still DTC are set, replace ESBM \(Fuel door and drive modes Switch module\) in accordance with the Service Information. Flag the part to be returned to supplier for further part analysis.
