Attachment 10 - DTC 73 Chart - Isolation Valve Malfunction






DTC CHART TEST DESCRIPTION:
Number(s) below refer to circled number(s) on the diagnostic chart.
1. Checks condition of EBCM/EBTCM to BPMV connector and for presence of brake fluid in the EBCM/EBTCM.
2. Checks the integrity of the affected valve solenoid circuitry internal to the BPMV, and the valve solenoid coil.
3. Checks for solenoid circuit short to ground (BPMV case).
4. Checks for continued DTC setting after validating that the circuitry and the solenoid valves are good. If DTC resets, the EBCM/EBTCM is likely malfunctioning.
