Data Identifier (Did) D020 Table
Using the JLR approved diagnostic equipment, read the Data IDentifier (DID) D020 and check the snapshot data to determine the missing message source control module. Check the relevant control module for related DTC s and refer to the relevant DTC index.
Refer to the appropriate Wiring Diagrams , for schematic and connector information. and check the FlexRay bus between the relevant control module (for example as indicated by the snapshot data) and the PSCM.
If DID D020 is not supported, or if no fault is found, clear the DTC s and retest (do not replace any modules just on the basis of this DTC ) Check the PSCM FlexRay bus wiring harness and connectors. Check other modules on the FlexRay bus for U0080-81, U0080-82, U0080-87 check wiring harness for these modules and rectify appropriately:
- Gateway Module A (GWM)
- ABS
- TR
- Chassis Control Module (CHCM)
- Powertrain Control Module (PCM)
- TCM
- BCM
- Headlamp Control Module B (HCMB)
- NFSM
- Image Processing Module 'A' (IPMA)
- SASM
