The procedure covers Fuller Advantage Heavy Duty transmissions using the Electronic Clutch Actuator and Heavy Duty ECA Clutch, with the TECU monitoring engagement. For lubrication the document refers to CLSM0200, and it lists the Eaton support line (800) 826-4357 for further diagnostics. Technicians read the Clutch Inertia TP Delta in ServiceRanger under Vehicle Data Monitor and inspect the clutch housing for oil or grease contamination that can cause a slipping complaint. Manufacturer data is published on Eaton’s official Roadranger website.
Who needs this Fault Code 26 DTCs manual
Technicians and workshop owners diagnosing clutch slip complaints or an active fault use this manual to check the IBkTp Delta and perform a correct clutch reset before replacing the clutch. A false code can also be set when a J1939 Data Link issue is present, so related codes are checked first.
