01435

From Ross-Tech Wiki

01435 - Brake Pressure Sensor 1 (G201)

01435 - Brake Pressure Sensor 1 (G201): No or Incorrect Basic Setting / Adaptation

Possible Symptoms

  • Malfunction Indicator Light (MIL) active

Possible Causes

  • Basic Setting not performed

Possible Solutions

  • Perform Basic Setting


01435 - Brake Pressure Sensor 1 (G201): Electrical Fault in Circuit

Possible Causes

  • Brake Pedal Switch (F) faulty/jammed
  • Brake Pressure Sensor 1 (G201) faulty

Possible Solutions

  • Check/Replace Brake Pedal Switch (F)
    • See Measuring Blocks
  • Check/Replace Brake Pressure Sensor 1 (G201)
    • ABS Hydraulic Unit (N55) may need to replaced
    • Perform Brake Pump Bleeding
    • Perform Brake Pressure Sensor 1 (G201) Basic Setting
    • Replace Brake Electronics Control Module (J104)

Special Notes

  • When found in RoW (Rest of World) MK60 ABS/ESP Brake Systems check to see if the Repair Kit documented in the following TPIs is compatible:

If Part Number 1K0-698-517-B is compatible, using the Repair Kit allows to replace the Hydraulic Control Unit (HCU) (which contains the (N55) Hydraulic Unit and (G201) the Brake Pressure Sensor 1) separate from the Control Module which will reduce the Repair Costs.


01435 - Brake Pressure Sensor 1 (G201): Implausible Signal

Possible Symptoms

  • Malfunction Indicator Light (MIL) active

Possible Causes

  • Brake Pedal Switch (F) faulty/jammed
  • Brake Pressure Sensor 1 (G201) faulty

Possible Solutions

  • Check/Replace Brake Pedal Switch (F)
    • See Measuring Value Blocks (MVB)
  • Check Brake Pressure Sensor 1 (G201)
    • See Measuring Value Blocks (MVB)
  • Check/Replace Brake Electronics Control Module (J104) and/or ABS Hydraulic Unit (N55)

Special Notes

  • When found in Bosch ESP Brake Systems:
    • The Bosh 5.x ABS modules drop communication at road speeds which makes it difficult, if not impossible, to log live measuring block data. If the Brake Light Switch is suspected as faulty and causing a G201 fault:
      • Try logging the Engine or Transmission for brake light switching.
      • Drive with the Cruise Control on and see if the system works as per design. If the CCS will not operate or the CCS does not shut off when the brakes are applied the Brake Light Switch may be faulty.
