SCP (J1850) Invalid or Missing Data for Gateway

Jump to the fix

Severity

Medium

Can I keep driving?

Usually drivable, but get it diagnosed without delay.

First step

Read the stability control module first, because the root cause is usually stored there rather than in the engine control unit.

What does it mean?

U1141 is a Network (CAN bus, module communications) fault code. It indicates: Lost ESP Torque Request Message . This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.

Symptoms

  • ABS, traction control and ESP warning lamps illuminated together
  • Stability and traction control disabled, with no intervention when a wheel slips
  • MIL (check engine lamp) on and cruise control refusing to engage
  • Reduced engine power or limp mode in some cases
  • Hill hold and other functions that rely on the stability control system unavailable
  • Fault often appears after a battery change, jump start or bodywork repair

Likely causes

  • Open or shorted CAN wiring between the stability control unit and the engine control unit
  • Stability control module without power or ground because of a blown fuse or a corroded connector
  • The stability control system already in a fault state, for example after a wheel speed sensor failure, so it stops sending torque requests
  • Low system voltage after a jump start, a deeply discharged battery or a failing alternator
  • Corroded terminals in a connector shared by the ABS unit and the engine harness
  • Coding or software mismatch after the stability control unit or the engine control unit was replaced
  • Internal failure of the stability control unit

How to fix it

  1. Scan all modules and note whether the stability control unit reports its own faults, such as a wheel speed sensor code
  2. Test battery condition and charging voltage, since low voltage alone can stop the torque request message
  3. Check the fuses, supply voltage and ground at the stability control unit under load
  4. Measure the CAN pair between the stability control unit and the engine control unit for continuity, shorts and correct resistance
  5. Inspect connectors near the ABS unit for corrosion, brake fluid contamination and pushed-back pins
  6. Repair the wheel speed sensor or other stability system fault first, then clear the codes and retest
  7. Verify software and coding of both units after any replacement, and replace the stability control unit only as a last step
