Description of SID 233 – Pld-Mr Fault (Erroneous Data)
SID 233 indicates that a fault has occurred in the PLD-MR, making the PLD-MR data erroneous.
This diagnostic condition is typically:
- PLD-MR Failed or Programmed Incorrectly (233 12).
- Incorrect or Misprogrammed PLD-MR (233 14).
The PLD-MR or engine-resident control unit is located on the left-hand side of the engine. See Figure "Location of PLD-MR Control Unit" . The PLD-MR is connected by a proprietary datalink to the DDEC-VCU. All necessary data and information is exchanged through the datalink. The DDEC-VCU then broadcasts all information on the J1587 and J1939 data links, where it can be read by minidiag2.
