P2010 is the high-side counterpart of P2009 for the bank 1 flap drive: the control line carries voltage it should not, typically because it touches a supply wire or the actuator is shorted internally. GM's 2018 diesels judge a resistance to supply under 0.5 Ω, again 12 of 15 checks and Type B. The 2014 Cruze diesel looks at the line while the driver is switched on and needs the short for more than 3 s. GM's 2025 DC-motor swirl drive sets P2010 when more than 8 A flows through the H-bridge switches toward the supply in 240 of 300 samples. In the 2010 Saab 9-5 diesel it marks a swirl solenoid control line shorted to voltage; the shop check there uses a test lamp across the control and ignition pins while the valve is commanded between 95 and 5 percent. Output stages usually protect themselves, so the flaps simply stop moving.

Likely causes

Control wire shorted to a battery or ignition feed
Shorted winding in the solenoid or actuator motor
Output stage in the engine control module failed

Symptoms

  • Malfunction indicator lamp on
  • Flaps stuck in one position, change in low-speed torque
