Modern vehicles are sophisticated mobile networks. Each system within a car, from the engine to the infotainment, relies on computers, also known as control modules, to operate and monitor its functions. These modules aren’t isolated; they communicate with each other through complex networks, sharing information essential for the vehicle’s overall performance. This intricate communication system, while enhancing vehicle capabilities, also increases the complexity of automotive diagnostics and repair, especially for brands like Chrysler that have a rich history of evolving electronic systems.
For independent automotive repair businesses, this complexity underscores the importance of factory-level diagnostic tools, often referred to as scan tools. While aftermarket scan tools serve a purpose, factory scan tools and comprehensive service information become crucial for effectively and profitably servicing today’s diverse vehicle fleet. Investing in the right tools and knowledge is paramount to ensure accurate diagnoses and efficient repairs. For Chrysler vehicles, understanding the evolution of their scan tools is key to providing top-notch service. Let’s delve into the world of Chrysler scan tools, exploring their history and the tools available today.
The Evolution of Chrysler Scan Tools
Chrysler has a noteworthy history in diagnostic tools, having introduced six different factory scan tool interfaces and five distinct scan tool platforms in just the last 14 years. This rapid evolution reflects the increasing sophistication of their vehicles and the diagnostic technology required to service them. Let’s trace this evolution, starting from the era of OBD 2.
DRB 3
The DRB 3 (Diagnostic Readout Box III) was a pivotal tool in Chrysler diagnostics. This handheld factory scan tool was designed for pre-CAN (Controller Area Network) Chrysler vehicles. However, its versatility extended to non-CAN, Global OBD 2, and basic oscilloscope functionalities. While the oscilloscope was rudimentary compared to modern dedicated units, the DRB 3 was renowned for its reliability and, crucially, its timeless operation – it doesn’t require ongoing subscriptions to function. For Chrysler module programming on non-CAN vehicles using the DRB 3, a Tech Authority Subscription is necessary to access and download the required calibration files. Early models (pre-1998) and specific applications like Chrysler-branded Mercedes or Mitsubishi vehicles (e.g., Chrysler Crossfire, Dodge Sprinter) necessitated Super Cards and specialized adapters and cables for proper diagnosis and function.
Star Scan
Stepping into the CAN era, Chrysler introduced the Star Scan. This handheld tool marked Chrysler’s first factory scan tool specifically for CAN-based vehicles. Notably, it was not backward compatible with non-CAN vehicles, except when used with the DRB 3 Emulator included in the early wiTECH application (discussed later). The Star Scan, while innovative for its time, quickly became outdated due to slow processing speeds and hardware limitations that struggled to keep pace with software updates. Like the DRB 3, the Star Scan itself didn’t require a subscription to operate, but updates and Chrysler module programming demanded a Tech Authority subscription. The Star Scan is no longer sold or officially supported, highlighting the rapid advancements in diagnostic technology.
Star Mobile
Chrysler’s next move was the Star Mobile, their first scan tool interface designed for laptop integration. The Star Mobile interface served as the hardware bridge connecting to the vehicle’s DLC (Data Link Connector). Functionality depended on a laptop loaded with the Star Mobile Desk Top Client software, initially distributed on discs. Importantly, the Star Mobile interface was also forward-compatible, serving as a functional interface for the forthcoming wiTECH application.
Star Mobile Desk Top Client & wiTECH VCI Pod
The Star Mobile Desk Top Client software was short-lived, soon superseded by the wiTECH application and its initial software iteration, the wiTECH Desk Top Client. The Star Mobile interface, however, retained its utility, functioning with the wiTECH application for a significant period. The wiTECH VCI Pod was launched concurrently with the wiTECH application. Initially, Chrysler dealerships were required to purchase a comprehensive wiTECH package, including a specialized gateway (router) and mandatory setup by a dedicated installation team. For aftermarket facilities, the initial wiTECH package was a substantial investment, around $8,000, encompassing a year’s wiTECH license, support, and programming capabilities. Later, a more budget-friendly option, wiTECH Lite, was introduced at approximately $4,000, offering a less expensive router and email-based support. Significantly, the wiTECH application soon incorporated a DRB 3 emulator, enabling users to diagnose and program non-CAN Chrysler vehicles through the wiTECH platform. While convenient, emulators, including the DRB 3 Emulator, often fall short of the performance of dedicated hardware tools, although the wiTECH emulator improved with software updates.
wiTECH MicroPod & MicroPod 2
The wiTECH MicroPod represented the next generation of Chrysler factory scan tool interfaces. This compact, pocket-sized dongle connected directly to the vehicle’s DLC. Unlike its predecessors, the wiTECH MicroPod required an active wiTECH subscription to function. Without a valid subscription, the tool would time out and become unusable. However, users with the original VCI Pod and wiTECH software version 13.03.38 or earlier could operate in a limited offline mode for basic diagnostics, albeit without programming capabilities or access to newer vehicle models and application features.
Tech Authority is the essential aftermarket portal for acquiring subscriptions needed to download Chrysler flash files for module programming, irrespective of the scan tool or programming device used. Subsequently, the MicroPod 2 was released to address compatibility issues with certain vehicle models. Further evolution brought wiTECH 2, designed to enhance cybersecurity and mitigate vehicle theft concerns. The launch of wiTECH 2 signaled the impending sunset of the original wiTECH application. Compatibility with wiTECH 2 required a MicroPod 2 with a serial number of WPS-31560 or higher, rendering older MicroPods incompatible. Upgrading a compatible MicroPod 2 to wiTECH 2 permanently locked it to the new platform, preventing its use with the original wiTECH application. While the original wiTECH application was officially discontinued in late 2017, it reportedly remains accessible to dealerships due to wiTECH 2’s incomplete compatibility with some older CAN platforms. WiTECH 2 is a cloud-based application, mandating a stable internet connection for scan tool operation.
DRB 3 Emulator (Standalone)
The DRB 3 emulator within wiTECH 2 was discontinued. For aftermarket shops needing factory-level diagnostics for non-CAN Chrysler vehicles, the standalone DRB 3 Emulator from Controller Technologies Corporation emerges as the primary legitimate option. While emulators inherently have limitations, this particular DRB 3 emulator is considered highly capable, even potentially surpassing the original DRB 3 in handling early CAN PCI Hybrid vehicles. It offers near-complete factory scan tool coverage for non-CAN Chrysler vehicles, with similar exceptions as the original DRB 3 for Chrysler-branded Mercedes and Mitsubishi models (though a PC-based DRB 3 Multiplexer is available for Crossfire and Sprinter applications). The kit includes non-powertrain ECU calibration files for body and chassis module programming without a Tech Authority Subscription, while powertrain programming necessitates a subscription.
