P1800 Suzuki Transmission Clutch Interlock Safety Switch Circuit Failure

P1800 Suzuki Transmission Clutch Interlock Safety Switch Circuit Failure

Possible causes
  • Harness or connectors (The solenoid valve circuit is open or shorted.)
  • VIAS control solenoid valve
    • What about the obd code?
  • An excessively low or high voltage signal is sent to ECM through the valve
    • Symptoms
    – Engine Light ON (or Service Engine Soon Warning Light)
    P1800 Suzuki Description

    The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.
