U1153 on 2022 Jeep Wagoneer: Lost Communication With Wiper Module Fixes

What's Unique About the 2022-2022 Jeep WAGONEER

The 2022 Jeep Wagoneer (WS platform) is a modern, highly complex vehicle with numerous electronic modules communicating over a network. Communication codes like U1153 are relatively common on such platforms. Jeep has specifically identified that a software issue in the Body Control Module (BCM) can cause this and a host of other communication DTCs, prompting the release of a TSB to update the BCM software. This suggests that the root cause is often software-related rather than a simple hardware failure. The platform's shared architecture with the Ram 1500 (DT) means both vehicles can suffer from this identical software flaw.

Symptoms You May Notice

• Windshield wipers do not work at all
• Wipers operate intermittently or on the wrong speed setting
• Wipers stop in the middle of the windshield
• Check engine light or other warning messages on the dashboard
• A cluster of other communication-related DTCs stored along with U1153

Most Likely Causes

1. Body Control Module (BCM) Software Glitch 🔴 High Probability Jeep issued TSB 08-153-22 REV. A specifically to address this and other communication codes by reprogramming the BCM with updated software. This is the most widely reported and confirmed fix by owners in forums.
   How to confirm: A Jeep dealership or a qualified shop with a wiTECH scan tool can check the current BCM software version against the latest available updates mentioned in the TSB. The presence of multiple 'U' codes listed in the TSB is a strong confirmation.
   Typical fix: Reprogramming (flashing) the BCM with the latest software version as per TSB 08-153-22 REV. A / RSU 22-199. This is often covered under warranty.
   Est. part cost: $0
2. Wiring Harness or Connector Fault 🟡 Medium Probability The Wagoneer platform, like many modern vehicles, has extensive wiring that can be susceptible to damage. Owners have reported various electrical issues, sometimes traced back to wiring, though this is less common for U1153 than the software issue.
   How to confirm: Visually inspect the wiring harness and connectors leading to the windshield wiper smart module for signs of chafing, corrosion, or loose pins. Perform continuity and pin-out tests with a multimeter after the software has been confirmed to be up-to-date.
   Typical fix: Repairing the damaged section of the wiring harness or cleaning/replacing the affected connector.
   Est. part cost: $10-$50
3. Failed Windshield Wiper Smart Module ⚪ Low Probability While less common than software or wiring issues, the module itself can fail internally. This should only be considered after the BCM software and wiring have been ruled out.
   How to confirm: After confirming the wiring and software are good, a technician can use a high-level scan tool to attempt direct communication with the module. If it fails to respond, the module is likely faulty.
   Typical fix: Replacing the windshield wiper smart module. This module is integrated with the wiper motor and linkage assembly.
   Est. part cost: $300-$400

Rare But Worth Checking

• Low Battery Voltage or Failing Battery: Low system voltage can cause unpredictable communication errors between modules on modern, sensitive vehicles. Many Wagoneer owners have reported widespread electrical issues stemming from battery problems, which can trigger a cascade of 'U' codes.

Diagnosis Steps

1. Connect a professional-grade scan tool (like wiTECH) to the vehicle.
2. Scan all modules for Diagnostic Trouble Codes (DTCs). Note if U1153 is present with a cluster of other communication ('U') codes, especially those listed in TSB 08-153-22 REV. A.
3. Check for applicable Technical Service Bulletins (TSBs) for the vehicle's VIN, specifically TSB 08-153-22 REV. A or newer revisions. This may also show up as RSU 22-199.
4. If the TSB applies and the BCM software is outdated, perform the BCM reprogramming procedure as instructed. This is the most likely fix and should be the first step.
5. Clear all DTCs and perform a full vehicle sleep cycle (letting all modules power down for several minutes), then re-scan to see if U1153 returns.
6. If the software is up to date or the flash does not resolve the issue, locate the windshield wiper smart module (typically part of the wiper motor assembly under the cowl).
7. Inspect the wiring harness and electrical connector to the module for any signs of physical damage, corrosion, or moisture intrusion.
8. Using a multimeter and wiring diagram, check for proper power, ground, and network signal integrity at the module's connector.
9. If wiring, power, and ground are confirmed to be good, the wiper smart module itself is the likely point of failure and should be replaced.

Technical Service Bulletins (TSBs) & Recalls

• 08-153-22 REV. A / RSU 22-199: This TSB, released October 25, 2022, advises reprogramming the Body Control Module (BCM) to resolve U1153 and a long list of other 'Lost Communication' codes on 2022 Wagoneer/Grand Wagoneer and Ram 1500 vehicles.

Platform-Specific Known Issues

• The 2022 Wagoneer is subject to TSB 08-153-22 REV. A, which involves a software update for the Body Control Module (BCM) to fix a range of communication DTCs, including U1153.
• Owners of the Wagoneer platform have reported numerous and varied electrical problems, from battery drain to complete vehicle shutdown, suggesting a sensitivity in the vehicle's electrical architecture.
• This specific BCM software issue also affects its platform-mate, the Ram 1500 (DT), confirming it's a design-level issue rather than a random failure.

Mechanic-Grade Diagnostic Values

• LIN Bus Voltage (at Wiper Smart Module connector) — expected: Approximately 12V (or system voltage) when the bus is at rest/not communicating. The voltage will toggle lower, towards 1V, when data is being transmitted.. Failure: A steady 0V may indicate a short to ground. A voltage significantly lower than battery voltage at rest could indicate a wiring issue or a fault in a module on the bus. A stable battery charger is recommended during testing to avoid false readings.

Scan Tool Commands That Help

• wiTECH: BCM Reprogramming — This is the primary repair step if TSB 08-153-22 REV. A applies. It updates the Body Control Module software to fix the communication bug causing the code.
• wiTECH: Actuator Tests / Bidirectional Controls — After verifying software is up-to-date, a technician can use this function to directly command the wiper motor/module to activate. If the module responds to the scan tool command but not the steering column switch, it points to an input issue. If it fails to respond at all, it suggests a wiring or module failure.
• wiTECH: Restore Vehicle Configuration — This function is required after replacing the Body Control Module (BCM) to ensure the new module is properly configured for the vehicle's specific options and VIN.

Wiring & Ground Locations

• Wiper Motor Assembly — Under the plastic cowl panel at the base of the windshield.. This is the physical location of the Windshield Wiper Smart Module, which is integrated into the motor assembly. The connector and harness at this location are the primary points for checking power, ground, and the LIN bus signal.
• Main Harness Connectors (potential issue area) — Behind the passenger side front wheel well liner.. On modern Jeep/Stellantis platforms, large CAN bus and network connectors are located in this area. Technicians have found that moisture intrusion in these connectors can cause widespread communication failures, leading to multiple 'U' codes, even if the connector is not directly for the failing module. If the BCM flash doesn't work, inspecting these connectors for moisture or corrosion is a critical next step.

Real Owner Repair Stories

• Jeep Wrangler Forums (JL / JLU) (2021 Jeep Wrangler JL Rubicon (modern Stellantis platform with similar network architecture)) — After water intrusion in the passenger footwell, the dashboard was 'going nuts, wipers going, lights flashing.'
  ❌ Tried (didn't work) Replacing the BCM and having the dealer program it. The new BCM would still not communicate with other modules, and the vehicle would not start.
  ✅ What actually fixed it The mechanic found and dried out large harness connectors located behind the passenger wheel well liner that had moisture in them. After drying them and applying dielectric grease, the new BCM was able to communicate with all other modules and the vehicle functioned correctly.
