SUBJECT

New Detroit Standard Diagnostic Times for ECU

 Detroit
Standard
Diagnostic
Times

In the continued collaboration with the Joint Application Development (JAD) committee, DTNA
created additional Standard Diagnostic Times (SDTs) to support the service network and streamline
the claim submittal process. The new SDTs, which are available for immediate use, may be applied to
claims related to the following Detroit electronic control unit (ECU) modules:
• Motor Control Module (MCM)
• Common Powertrain Control Module (CPC)
• After Treatment Control Module (ACM)
• Transmission Control Module (TCM)
There are three (3) levels of SDTs: Easy, Moderate, and Difficult. Select the level of SDT that
matches the diagnostics performed. Refer to the Includes and Comments fields under each SDT in
the Detroit Warranty System to review the operations that are included. To claim diagnostic time
that was required beyond the SDT, use General Diagnostic Time (labor code 939-1010E) and provide
a detailed explanation in the appropriate claim narrative section; please see Important Warranty
Information letter 15-003 for more information about applying General Diagnostic Time. The table
below provides the new SDTs and applicable engine series, respectively.
