TCS Does Not Fully Operate

NOTE: TCS will disable torque reduction when there is a possibility of engine stalling to prevent engine from stalling.

Ensure tire size and tire air pressure meet manufacturer's specification. Replace tires or adjust tire air pressure as necessary. If tire size and tire air pressure meet manufacturer's specification, go to next step.
Check for engine control system related DTCs. See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. If engine control system related DTCs are present, repair as necessary. If no engine control system related DTCs are present, perform TRACTION CONTROL SYSTEM (TCS) OPERATION CHECK .
