This error only exists on the Xbox 360 S Trinity motherboards. It may exist on Corona and newer as well, this is still being analyzed.

ERROR_V_CPUVCS

VREG_CPUCORE_VCS_PWRGD is driven high by the V_CPUVCS controller as long as the rail is within tolerance. If V_CPUVCS ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter EC_FATAL and the 0032 code to be displayed on the front panel.

Short Circuit

• Check if V_CPUVCS is shorted
• If it is, check circuit components to localize short
  • Lift at least 1 pin of the inductor to isolate the rail before checking

Enable and Power Good

• Everything in this section must be checked quickly, as the SMC will shut down power upon entering EC_FATAL
• Check CPU_SRVID signal, pullup, and pulldown
  • If pullup and pulldown are fine but signal is missing, replace CGPU
• Check VREG_CPUCORE_VCS_PWRGD
  • If present, replace Southbridge
  • If missing, check pullup
    • Note that the pullup for this signal is part of the V_CPUCORE circuit
    • If pullup is fine, continue below

VREG Circuit

• Everything in this section must be checked quickly, as the SMC will shut down power upon entering EC_FATAL
• Check if V_CPUVCS is present
• If it is, replace the PWM driver and recheck PWRGD
• If it isn't, check VREG and PWM driver
