Hey I have a NISSAN CARAVAN NV350 YEAR 2012. Two weeks ago I replaced an old battery with a new one and by doing that I immediately got a ABS light on my dash board with an error code C1109 Speed control Actuator assembly cable release Failure. I have tried
1. Clearing the code
2. Replacing the fuse
3. Physically check the rear right and left wheel harness
Nothing is working so far.All this because I replaced my old battery with a new one
-
Some shops reported that a low battery charge will set the code. But obviously that is not your problem because you replaced the battery. My suggestion is to check the voltage of the battery with the engine running. The code will be set if the voltage is 10 V or less or 16 V or more. You could have a bad alternator that is not properly charging. Do you have any more symptoms or codes?
-
Below are the results of the battery test
while the ignition was off the battery was at 12.2V
Draw down during ignition went down to 9.42V
Charging voltage was at 13.02V -
Although 9.42V is within the range for most vehicles, it could be too low for your vehicle. Did you use the factory recommended battery? If you did, then check the battery terminals and cables for corrosion.

I'm sorry to hear you're experiencing these issues with your 2015 Nissan Versa Note SV. Based on the codes you've provided and the components you've already replaced, it seems you're dealing with multiple electrical circuit issues that may be interconnected. Let's break down each of the diagnostic trouble codes (DTCs) and explore possible solutions.
Diagnostic Trouble Codes (DTCs)
-
P0037: Heated Oxygen Sensor (HO2S) Heater Control Circuit Low (Bank 1 Sensor 2)
- This code indicates a low voltage in the heater control circuit of the downstream oxygen sensor.
-
C1105: Right Front Wheel Sensor Open Circuit
-
C1106: Left Rear Wheel Sensor Open Circuit
-
C1107: Right Rear Wheel Sensor Open Circuit
- These codes suggest that the wheel speed sensors are not communicating properly, possibly due to open circuits.
-
C1109: Battery Voltage Abnormal (Brake Control)
- This code indicates an issue with the battery voltage supplied to the brake control system.
-
C1142: Pressure Sensor Output Voltage Low
-
C1143: Pressure Sensor Output Voltage High
- These codes point to inconsistent voltage readings from the brake pressure sensor.
Potential Causes
Given the variety of codes affecting different systems (engine, ABS, and brake systems), a common denominator is likely causing these issues:
-
Electrical Issues:
- Blown Fuses or Fusible Links: A blown fuse in a circuit shared by these components could cause multiple failures.
- Faulty Grounds: Poor grounding can lead to voltage irregularities across various sensors and modules.
- Damaged Wiring Harness: Physical damage or corrosion in the wiring harness can disrupt signal transmission.
- Connectors: Loose or corroded connectors can cause open circuits and voltage issues.
-
Battery and Charging System:
- Alternator Problems: An alternator that isn't charging properly can cause low voltage issues.
- Battery Terminals: Corroded or loose battery terminals can lead to voltage drops.
-
Control Module Failures:
- ABS Control Module: A malfunctioning module can throw multiple wheel sensor and pressure sensor codes.
- Engine Control Module (ECM): While less likely, a faulty ECM can misinterpret sensor signals.
Recommended Steps to Diagnose and Fix the Issue
-
Inspect Fuses and Fusible Links:
- Check all relevant fuses related to the ABS, brake system, and engine sensors.
- Replace any blown fuses with the correct amperage rating.
-
Check Battery and Charging System:
- Test the battery voltage with the engine off and running. It should be around 12.6V when off and 13.7-14.7V when running.
- Ensure the alternator is functioning correctly.
- Clean and tighten battery terminals and ground connections.
-
Examine Grounds and Wiring:
- Locate and clean all ground points connected to the affected systems.
- Inspect the wiring harness for signs of damage, wear, or corrosion.
- Pay special attention to the wiring near the wheel sensors and oxygen sensors.
-
Inspect Wheel Speed Sensors:
- Remove and clean the wheel speed sensors to eliminate any debris or corrosion.
- Check the connectors for secure attachment and absence of corrosion.
- Test the resistance of each sensor to ensure they are within specification.
-
Test the Oxygen Sensor Heater Circuit:
- Use a multimeter to check the voltage and resistance in the heater circuit of the downstream O2 sensor.
- Ensure the wiring and connectors are intact and properly connected.
-
Brake Pressure Sensor Evaluation:
- Inspect the brake pressure sensor and its wiring for any signs of damage.
- Test the sensor output voltage to see if it falls within the manufacturer's specifications.
-
Professional Diagnostic:
- If the above steps do not resolve the issue, it may be necessary to use advanced diagnostic equipment.
- A professional technician can perform module scans to check for communication errors between control units.
Possible Underlying Issues
- Common Ground or Power Supply Problem: Multiple sensor failures often point to a shared ground or power supply issue.
- Faulty ABS Module: Since several codes relate to the ABS system, the module itself may be defective.
- ECM Software Glitch: Although less common, sometimes updating the ECM software can resolve unexplained DTCs.
Next Steps
- Prioritize Safety: Since some of these codes affect the braking system, it's important to address them promptly to ensure vehicle safety.
- Consult a Professional: Given the complexity and potential safety implications, consider taking your vehicle to a certified Nissan technician for a thorough diagnosis.
- Document Everything: Keep a record of all repairs and diagnostics performed. This information can be invaluable for technicians.
I hope this information helps you identify and resolve the issues with your Nissan Versa Note. If you have further questions or need clarification on any of the steps, feel free to ask.
