TCS Control Unit
- TCS control unit includes self-diagnostics. It will store up to 3 codes. Self-diagnostic system is functioning as long as engine is running. When a problem occurs, the TCS indicator light will come on and trouble code(s) will be stored. If the ignition is turned off and engine restarted, the TCS light will not come on (unless another problem is present). Any trouble codes will remain in memory.
- The most recent code will appear first. The oldest stored trouble code will appear last. If more than 3 trouble codes were detected by TCS control unit, they will be erased from the memory. Vehicle may have to be driven to obtain complete self-diagnostic results.
