The fault code 53 is an ECM IMMOBILIZED ERROR.
The immobilizer anti-theft system thinks the key is invalid. If it detects an error, it will;
Disable the fuel injector circuit--- Disable the fuel pump circuit---Disable the ignition coil.
Code 53 will set when:
1- The Eectronic Control Module (ECM) does not receive the signal from the Immobilizer Control Unit (ICU) within 0.9 seconds when vehicle is stationary, or 1.8 seconds when vehicle is moving.
2- The ICU sends the ECM an incorrect release message more than 5 times.
3- The above conditions continue until the ignition is switched off.
I hope this helps.
