TCS Is Not Working Sufficiently
CAUTION: Recheck the diagnostic trouble code after repair completion. For the steps which have an asterisk (*), inspect the connection of the connector with the terminal and for any damage first. If the connection is poor, securely connect them, or repair or replace the appropriate parts as necessary. Wiggle and pull the wire harness to inspect each wire for corrosion, bent or loose terminals and poor wire terminal crimps.
NOTE: The ABS warning light normally illuminates for 2-4 seconds after ignition switch is turned to ON.
^ If any symptoms have occurred in the past but are now okay, malfunction of related harness could be the possible cause and thus ABS CM is normal.
