Product Featured: iCarsoft CR ULTRA P
🔍 Overview
In this tutorial, we follow a real-world case of coding a replacement injector on a Mercedes GLA 2.1 CDI diesel using the all-new iCarsoft CR ULTRA P Bluetooth diagnostic tool. The process involves injector parameter teaching (quantity adjustment) after installing a new injector on cylinder 4.
🧰 Tools & Requirements
- iCarsoft CR ULTRA P diagnostic tool
- Stable Bluetooth connection
- VIN recognition enabled via Intelligent Diagnosis
- Injector code from OEM part (ensure accuracy & capitalization)
📋 Real Case Example
During this Mercedes GLA injector coding, the technician demonstrated live how the CR ULTRA P automatically detects VIN, runs a full system topology scan, and accesses the Engine Control Module (ECM).
After selecting Special Functions → Teaching Processes → Injector Quantity Adjustment, the user entered the new code for cylinder 4 (9YZ). The CR ULTRA P overwrote the old value and confirmed with “Adjustment Value Transferred”. Upon restart, the engine ran smoothly with no further injector errors — proving the coding was successful.
