C1130 ABS control unit not recognising an engine computer signal (Nissan and Infiniti)

Nissan ABS "engine signal" code

C1130 in short

On Nissan and Infiniti vehicles, C1130 means the ABS control unit is not recognising a signal from the engine computer. Nissan says engine trouble codes must be diagnosed and cleared first. Anti-lock, stability control and some driver aids can be affected, so have it inspected soon.

C1130 is stored by the ABS control unit, not the engine computer. It reports that an output signal it expects from the engine computer is missing or wrong. Nissan and Infiniti bulletins label it "engine signal".

Because the cause is upstream, the bulletins say to diagnose engine P-codes first, erase everything, then see whether C1130 returns. Owners show it with P0101 and P0340, and a 350Z dealer invoice shows it after camshaft and crankshaft sensor work.

Features that rely on that signal, such as forward emergency braking, intelligent cruise control and VDC/ABS/TCS, can be affected while it is set.

Pick your make

C1130 is a manufacturer-specific code: its meaning depends on who built the car.

Other makes: meaning not verified. Check with a scan tool that reads manufacturer definitions.

Most likely causes

  1. An engine fault that is sending missing or wrong signals

    Supported by vehicle data
    Why it ranks here
    Nissan and Infiniti service information says absent or incorrect engine computer signals, shown by P-codes, may trigger C1130. Owner reports pair it with P0101 and P0340.
    What would change this
    Rises if engine P-codes are stored with it. Falls if no engine codes exist and C1130 returns after the engine is clear.

  2. ABS control unit or its communication

    Possible — needs testing
    Why it ranks here
    If the engine side is clear and the code keeps returning, the fault may be in what the ABS unit receives. No bulletin we read names this, so it ranks last.
    What would change this
    Rises if C1130 returns after all engine codes are repaired and erased. Falls if it stays away.
    How to test the brake system control module (abs module)

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read all stored codes from the engine, ABS and stability control systems and note any engine P-codes with C1130.

Symptoms

  • ABS, VDC or traction control light on
  • Forward emergency braking or intelligent cruise control not available
  • Engine codes stored at the same time as the ABS code
  • Red BRAKE light on or pedal feel changes Gets more serious: stop and have it checked.

How to fix

This is a safety-critical system, so we explain the code but don't give repair steps. Have it inspected by a qualified technician.

    Diagnosis information for ABS DTC C1130

    2013altima · NHTSA 10119282

    Says to diagnose, repair and erase engine P-codes first because C1130 reports an engine computer signal the ABS unit does not recognise.

    We couldn't confirm whether this bulletin is still current, so it doesn't count as confirmation.

Infiniti

  • 2015 · QX60

    Supported by vehicle data

    Infiniti bulletin ITB16-047 gives the C1130 diagnosis guidance. Only the NHTSA text was read; whether it is current is not verified.

    Diagnosis information for ABS DTC C1130

    2015qx60 · NHTSA 10119264

    Infiniti version of the same guidance: clear engine P-codes first.

    We couldn't confirm whether this bulletin is still current, so it doesn't count as confirmation.

  • P0101Airflow sensor reading doesn't match what the engine computer expects for the throttle opening

    Shares causes Supported by vehicle data

    A Sentra owner reports P0101 stored with C1130; Nissan says engine P-codes come first.

  • P0340Camshaft position sensor circuit fault (bank 1 or single sensor)

    Primary / secondary Supported by vehicle data

    Likely primary: P0340. A 350Z dealer invoice shows P0340 and C1130 together, repaired with camshaft and crankshaft sensors.

C1130 questions

Should I replace the ABS module for C1130?

Not first. Nissan says engine P-codes must be repaired and erased before C1130 is judged.
