The inlet valve solenoid circuits are supplied with battery power when the ignition is in the ON position. The EBCM/EBTCM controls the valve functions by grounding the circuit when necessary.
The EBCM/EBTCM senses a discrepancy in the circuit such as:
• | An open. |
• | A short to ground. |
• | A short to voltage. |
• | A malfunction DTC stores. |
• | The ABS/TCS disables. |
• | The ABS/TCS indicator(s) turn on. |
• | Condition for DTC is no longer present and scan tool clear DTC function is used. |
• | 100 ignition cycles have passed with no DTCs detected. |
The solenoid valve circuit and the solenoid coil are internal to the EBCM/EBTCM. No part of the solenoid circuit is diagnosable external to the EBCM/EBTCM. The DTC sets when there is a malfunction in the solenoid circuit internal to the EBCM/EBTCM only.
