ANCEL DS100 4-System OBD2 Scanner ABS SRS Transmission

A basic code reader talks only to the engine computer, so when the transmission light, the ABS light, or the airbag light comes on you are back to guessing. The ANCEL DS100 reads all four core systems, engine, transmission, ABS, and SRS airbag, so you can see the actual stored and pending codes in each module before you order a single part. For anyone diagnosing a shift complaint, that transmission module access is the difference between chasing a solenoid on a hunch and reading the code the TCM already set.

Beyond reading and clearing codes it carries seven service resets that come up constantly after a repair: oil light reset, brake pad reset, battery (BMS) registration, ABS bleeding, throttle body adaptation, steering angle (SAS) reset, and gear learning. The gear-learn and throttle functions matter on the transmission bench, since a valve body or throttle body swap on many late-model cars leaves the adaptives wrong until you relearn them. Function availability varies by make, model, and year, so confirm coverage for your vehicle first.

It runs on a 5-inch full touchscreen with an Android interface, uses AutoVIN to identify the car and load the right software in one step, and shows 4-in-1 live data so you can watch several PIDs on one screen while a fault acts up instead of relying on a code that already cleared. It checks I/M readiness before an emissions test, builds diagnostic reports you can save as a PDF or email straight off the tool over WiFi, and gets free lifetime updates. It covers OBDII vehicles from 1996 and newer across 100-plus brands. This is a full-system diagnostic and service-reset tool, not a bidirectional active-test scanner, so it does not command components on or off. Ships with a hard protective case, USB-C charging cable, and manual.
