Reading DTCS With Scan Tools
NOTE:
ABS/TCS is disabled whenever the EBTCM is communicating with a Scan tool.
When the ABS control module detects a fault, it stores a DTC in the General Information table (current DTCs) and signals the BCM to command the I/P cluster to illuminate the ABS telltale. When the ignition is switched Off, the current DTCs are moved to the History table (history DTCs) and cleared from the General Information table.
