Description
BOOST CONTROL SOLENOID CONTROL CIRCUIT

Output Driver Modules (ODM) are used by PCM to turn on
current-driven devices needed to control various engine and transaxle
functions. Each ODM can control up to 7 outputs, including boost
control solenoid, by supplying ground to device PCM is commanding on.
ODMs can diagnose each circuit individually. If ODM "A" output 5
(boost control solenoid driver circuit) detects an improper voltage
level, DTC is set.

Symptoms
You likely won't notice any drivability problems.

Causes

• An improper voltage level has been detected on boost control
  solenoid driver circuit.

Solutions

• Check for faulty connections or damaged harness at BCS
• Replace boost control solenoid.
