### Circuit Description

The inlet valve solenoid circuits are supplied with battery power when the ignition is in the ON position. The EBCM controls the valve functions by grounding the circuit when necessary.

### Conditions for Running the DTC

#### Criteria 1

• | The switched system battery voltage is greater than 8.0 volts.

• | The ignition voltage is greater than 9.0 volts.

#### Criteria 2

• | The switched system battery voltage is greater than 8.0 volts.

• | The ignition voltage is greater than 9.0 volts.

• | ABS is active.

### Conditions for Setting the DTC

Either of the following criteria is present for greater than 0.03 seconds.

### Criteria 1

The solenoid valve control circuit is open or shorted to ground.

### Criteria 2

The solenoid valve control circuit is shorted to voltage.

### Action Taken When the DTC Sets

• | The ABS/TCS disables.

• | The ABS/TCS indicator(s) turn on.

### Conditions for Clearing the DTC

• | Condition for DTC is no longer present and scan tool clear DTC function is used.

• | 100 ignition cycles have passed with no DTCs detected.

### Diagnostic Aids

The solenoid valve circuit and the solenoid coil are internal to the EBCM. No part of the solenoid circuit is diagnosable external to the EBCM. The DTC sets when there is a malfunction in the solenoid circuit internal to the EBCM only.
