How to fix C260D code ?
- Erratic camshaft position due to low oil pressure
- Faulty TCM or TCM programming
- Exhaust tube

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source.
Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.
