C0141 is not listed in the accessible J2012 tables. Saab documents it for the Bosch 5.3 TC/ABS of the 9-3 and 9-5 from 1998 and for the later 9-5 ESP as the left pressure-increase valve, kept apart from the wheel valve group code C2450; GM's chassis keyword list (PIP5094) includes it, and AA1Car's GM-based table calls it Left TCS Solenoid #1. Describing it as the left front inlet valve is therefore one reading of a valve that builds pressure in the left front brake circuit, above all during traction control. Saab tests the coil without pause for breaks and shorts, with the rolling check running above 6 km/h; a fault shuts down ABS, TCS and ESP and lights several warning lamps at once. Coil, wiring and the valve block are the usual suspects.

Likely causes

Open or shorted coil of the left pressure-increase valve
Poor contact between control unit and valve block
Failed valve driver in the control module

Symptoms

  • ABS, brake and central warning lamps on
  • TCS/ESP off indicator lit, no ABS, TCS or ESP function
