The Z Automotive Tazer JL Mini is an electronic plug-in device designed to modify vehicle settings and enable live functions for 2018-2020 Jeep Wrangler JL and 2020 Jeep Gladiator JT models. It connects to the vehicle's SGW module, located above the OBD2 diagnostic connector.
Function Description:
The Tazer JL Mini offers two main categories of features: Vehicle Settings and Live Functions.
- Vehicle Settings: These are permanent changes made to the Jeep's computer, such as tire size, gear ratios, or enabling/disabling certain features. These modifications remain active even after the Tazer JL Mini is unplugged.
- Live Functions: These are operations performed by the Tazer JL Mini only while it is physically connected to the vehicle. They provide real-time control and activation of various features.
Important Technical Specifications:
- Firmware: The device operates with firmware version 11.2.0-031220 (as of the manual's publication). Firmware updates are available periodically and can be installed via USB using the ZPU (Z Automotive Programming Utility) software.
- Connectivity: Plugs into the SGW module, which is located above the OBD2 diagnostic connector.
- Power Management: The Tazer JL Mini enters a sleep mode approximately 30 seconds after the Jeep shuts down.
- USB Cable: Uses a common "USB Mini B" data/charging cable for configuration and firmware updates.
Usage Features:
To access the settings menu, the EVIC screen must be showing the AUDIO screen. Then, press and hold the steering wheel LEFT ARROW and tap the Cruise “CANCEL” button. Pressing LEFT ARROW and CANCEL advances through menu items. To change/select a setting, press and hold LEFT ARROW and tap the Cruise "ON/OFF” (center) button. To exit quickly and safely, hold LEFT ARROW and press the Cruise "RES" button. After making changes, a "full reboot?" must be selected, which takes 2.5 minutes. Some settings require two sleep/wake cycles.

Configuration:
The Tazer JL Mini is configured using the ZPU (Z Automotive Programming Utility) software on a PC or Mac, connected via the supplied USB Mini B cable. This utility is also used for firmware updates and configuring light show options.
Unmarry Key:
When "Unmarry" is selected from the Tazer menu, all settings revert to their original state. If a "Not VIN XXXX" error occurs (e.g., second-hand device, lost vehicle access), an "Unmarry Key" can be purchased from the Z Automotive website after obtaining the key from the Tazer's EVIC menu. The key is entered using the EVIC menu (Left Arrow + Cruise+/-).
Maintenance Features:
- Firmware Updates: New firmware is released periodically and is free. It can be installed using the ZPU (Z Automotive Programming Utility) via a USB connection.
- Unmarrying: The Tazer JL Mini should be "Unmarried" and removed from the vehicle before dealer service to prevent potential issues or warranty concerns.
- Troubleshooting: The manual provides a troubleshooting guide for common issues like "No menu in EVIC," settings not taking effect, "service AWD" errors, ESS errors, hyperflashing turn signals, and security light issues. Solutions often involve sleep/wake cycles, radio reboots, or specific re-learn procedures.
