Circuit Description
The outlet 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. |
Action Taken When the DTC Sets
If equipped, the following actions occur:
| • | The EBCM disables the ABS/TCS for the duration of the ignition cycle. |
| • | The ABS indicator turns ON. |
| • | The Traction Off indicator turns ON. |
| • | The message center displays the Service Traction System message. |
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.
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Did you perform the ABS Diagnostic System Check? | -- | Go to Step 2 | |
2 |
Does the DTC reset as a current DTC? | -- | Go to Step 3 | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems |
3 | Replace the EBCM. Refer to Electronic Brake Control Module Replacement Did you complete the repair? | -- | Go to Step 4 | -- |
4 |
Does the DTC reset? | -- | Go to Step 2 | System OK |
