P0600

ALLDATA Editor Note: Code P0600 is a communication code, that is able to effect both the ECM and the Transmission Interface.

The CAN or Controller Area Network System is a high-speed serial interface for sharing dynamic signals between control modules.


DTC P0600
CAN Interface timeout Transmission Control Module Drive cycle A:Signal missing.

Possible causes by suggested order of priority:
- Connectors C193, ECM C637 (B).
- Open circuit - C193/16 (W) to C637/36 (W).
- Open circuit - C193/44 (Y) to C637/37 (Y).
- Short circuit - C193/16 (W) to vehicle earth.
- Short circuit - C193/44 (Y) to vehicle earth.
- Transmission control unit fault.
- ECM fault.

Connectors C193, ECM C637 (B).
- Check for connector not correctly latched, backed out pins, damaged pins, corroded pins

Open circuit - C193/16 (W) to C637/36 (W).
- Check resistance > 1M Ohm

Open circuit - C193/44 (Y) to C637/37 (Y).
- Check resistance > 1M Ohm

Short circuit - C193/16 (W) to vehicle earth.
- Check resistance < 5.0 Ohm

Short circuit - C193/44 (Y) to vehicle earth.
- Check resistance < 5.0 Ohm

Transmission control unit fault.
CHECK THE FOLLOWING:
- Run transmission control unit diagnostics.
POSSIBLE FAULTS
- Transmission control unit fault.

ECM fault.
CHECK THE FOLLOWING:
- Eliminate other possible causes of this fault.
- Check that transmission control unit diagnostics also reports a CAN interface time-out fault.
POSSIBLE FAULTS
- Faulty ECM.
