  • Standalone Operation: The DRB 3 does not require ongoing subscriptions to function for basic diagnostics.
  • Programming Capabilities: Could program non-CAN Chrysler modules with access to calibration files via a Tech Authority Subscription.
  • Super Cards and Adapters: Required Super Cards for early models (pre-1998) and specific applications like Chrysler-branded Mercedes and Mitsubishi vehicles (e.g., Chrysler Crossfire, Dodge Sprinter). Special adapters and cables were also necessary for certain models.

While the DRB 3 is no longer officially supported or sold by formal vendors, it remains a valuable tool for shops still servicing older Chrysler vehicles. Used DRB 3 units can be found, but sourcing parts and repairs can be challenging.

Transition Tools: Star Scan and Star Mobile

As Chrysler vehicles transitioned to CAN networks, new scan tools were needed. The Star Scan and Star Mobile represented Chrysler’s initial steps into CAN-based diagnostics.

• Star Scan:

  • CAN-Focused: The first Chrysler factory scan tool specifically designed for CAN-based vehicles.
  • Limited Backward Compatibility: Not compatible with non-CAN vehicles (except via the DRB 3 Emulator in early wiTECH).
  • Slow Performance: Known for its slow operation and quickly became outdated.
  • Subscription for Updates: Required a subscription for software updates and a Tech Authority subscription for module programming.
  • Discontinued: No longer sold or supported by Chrysler.

• Star Mobile:

  • Interface-Based System: Chrysler’s first interface designed to work with a laptop.
  • Star Mobile Desk Top Client Software: Required dedicated software installed on a laptop to function as a scan tool.
  • wiTECH Compatibility: Could function as an interface for the initial wiTECH application.

The Star Scan and Star Mobile were relatively short-lived, quickly superseded by the more robust wiTECH system.

wiTECH: The Modern Chrysler Factory Scan Tool Platform

wiTECH (wi-TECHnology) represents Chrysler’s current and primary factory scan tool platform. It has evolved through several iterations, offering comprehensive diagnostic and programming capabilities for modern Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo vehicles.
