hello

i ran a diagnostic on my car and had a total of 6 codes;

1. P303 CYL MISFIRE

2. U1000 CAN COMM CIRCUIT

3. P1212 TCS/CIRC

4. P1612 NATS MALFUNCTION

5. U1001 CAN COMM CIRCUIT

6. P0462 FUEL LEVEL SEN CIRC

i would appreciate you help urgently please

Is it true?? Is there anynone can tell me

the P1612, according to my manual indicates:
CHAIN OF ECM-IMMU
NATS MALFUNCTION
P1612
Communication impossible between ECM and IMMU
(“CHAIN OF ECM-IMMU” might be stored as a selfdiagnostic
result during the key registration procedure,
even if the system is not malfunctioning.)

This could be a wiring problem....

Good luck
