IMPORTANT WARRANTY INFORMATION
REF 14-027
Effective
Release

SUBJECT
Detroit's New Consolidated Labor Operations (CLOs)
 Enhanced CLOs
In an effort to support the service network and streamline the claim submittal process, effective
with claims filed on or after July 23, 2014, the Detroit Warranty Department is introducing
Consolidated Labor Operations (CLOs). The new CLO format allows Standard Repair Time (SRT)
to be combined with Standard Diagnostic Time (SDT) for specific failure modes.
 CLO Structure
With the CLO enhancement, Detroit has added two additional characters. The alpha indicator
(A), usually in the 8th character position of the labor operation, displays the included SDT for a
specific failure mode.
The numeric failure mode indicator (1), usually in the 9th character position of the labor
operation, identifies the specific failure mode. See below for a sample EPA10 Diesel Exhaust
Fluid (DEF) Metering Unit CLO that displays the multiple failure modes possible for a single
primary failed part (PFP).
Each failure mode will be described in detail in the Labor Description field. Selecting the correct
failure mode option is critical when filing a warranty claim. The CLOs are based on the fault
code or symptom and the repair path required to correct the complaint. Repair time could vary
between chassis model and engine service model; please refer to the applicable Labor Time
Guides (LTG) for appropriate times and included labor operations.

 CLO General
Guidelines
WARRANTY DEPARTMENT
13400 Outer Drive West
Detroit, MI 48239-4001
Steam cleaning and repair verification could be included in the CLOs, depending on the failure
mode. Repair verification that may be included in labor operations are:
• 132100 – Repair Validation
• 132200 – Engine Performance Test
• 062600 – Regeneration of the After Treatment Device (ATD) [Parked]
Admin time (939-6010A) is not included in the CLOs and needs to be submitted as its own line
item on the warranty claim.
Providing the fault code/symptom and repair path in the technician write-up and claim narrative
will assist in selecting the correct CLO for the failure.
 New CLOs
CLOs were created for the following components:
1. EPA10 After Treatment System (ATS) DEF Metering Unit
2. Belt Tensioner
3. Fuel Quantity Control Valve (QCV)
4. Oil Pan/Gasket
5. Hydrocarbon (HC) Doser Injector Valve
