CID 0295 FMI 09 Unable to Communicate with LHEX ECM
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects all of the following conditions:
- The engine is not cranking.
- Battery voltage is greater than 19 VDC for the last five seconds.
- Communication stops for 0.4 seconds after successful communication has been established with the machine ECM.
System Response:
The ECM will log the diagnostic code. The diagnostic code may be viewed on a display module or on the Caterpillar Electronic Technician (Cat ET). The check engine lamp will illuminate. All features that depend on the Cat Data Link will be disabled.
- None
Test Step 1. Perform the following test: CAT Data Link Circuit - Test
Results:
- OK - Stop.
