MID 136 f05 sid018 id for the ATC (traction control) has an open circuit, A dealer should be able to repair this fault if it does not clear up on its own. If it is not active than it is an old code.

You need to check the grounds and power supply to the ecm. Normally the ecm gets the power direct from the batterys.
This fault is set active if the ECM battery supply voltage drops below 6.2 volts while the keyswitch is in the ON position.
Make sure the ECM unswitched battery supply is coming directly from the battery and not the starter. If unswitched power is coming from the starter, it is possible for the battery voltage to drop low enough during cranking to set this fault active.
This fault can also be caused by resistance in the ECM battery supply (+) or (-) circuits. Resistance in these circuits can cause the voltage level at the ECM input to drop low enough to set Fault Code 434 active
Power Lost Without Ignition OFF. Supply voltage to the ECM fell below 6.2 volts momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF).
Possible no noticeable performance effects or engine dying or hard starting. Fault information, trip information, and maintenance monitor data can be inaccurate.
