JALTEST SERVICIOS CENTRALES – PROGRAMACIÓN ECU DETROIT DIESEL TCM (1 "COIN" REQUERIDO)

Jaltest Central Services — Detroit Diesel TCM ECU Programming (Part #70810054)

The Jaltest Central Services Detroit Diesel TCM (Transmission Control Module) ECU Update is a pay-per-use remote programming service where Cojali USA's certified technicians reprogram the transmission control module on Detroit Diesel-equipped trucks via the Jaltest software interface. At $495 per action, this handles dealer-restricted transmission controller programming on Detroit-integrated drivetrain systems without a dealer service appointment. An active Jaltest license is required. Detroit Diesel ECU programming actions, including TCM, are excluded from the complimentary Central Services actions bundled with Advanced Technical Support subscriptions.

What the TCM Controls

The Transmission Control Module in Detroit Diesel's integrated drivetrain manages the Detroit DT12 automated manual transmission — the 12-speed transmission matched with DD-series engines in Freightliner and Western Star trucks. The TCM controls:

• Shift scheduling and gear selection logic based on load, grade, and vehicle speed
• Launch and creep behavior calibration
• Engine-transmission communication for torque management during gear changes
• Fault detection and protection functions for the transmission system
• Customer-programmable parameters including shift aggressiveness and performance profiles

TCM programming is required when replacing a TCM, when a Detroit Diesel-issued calibration update is needed, or when a TSB procedure requires a TCM reflash to resolve a shift quality or fault code issue.

How the Central Services Process Works

1. Initial conditions verification — Jaltest confirms vehicle communication and service prerequisites
2. User request — Submit through Jaltest distributor or Cojali USA
3. Payment — $495 service fee processed
4. Schedule — Coordinate timing with Cojali's technician team
5. Remote execution — Cojali's certified technician performs TCM programming through your Jaltest session

Applicable Vehicles

This service applies to Detroit Diesel-integrated drivetrain systems — primarily Freightliner Cascadia and Western Star trucks equipped with the Detroit DT12 transmission matched to DD13, DD15, or DD16 engines. The DT12 is one of the most widely deployed automated manual transmissions in North American Class 8 trucking.

Important Notes

• Detroit Diesel ECU programming actions are explicitly excluded from the 2 complimentary Central Services actions included with ATS subscriptions — this applies to all four Detroit modules (ACM, CPC, MCM, TCM)
• Each module is a separate action and separate charge — a full Detroit Diesel programming event covering all four ECUs would be four separate $495 charges
• Active Jaltest CV license required
• Pay-per-use — $495 per action
