If the check engine light comes on in your car or bakkie, a LAUNCH scanner tells you why before you pay for a guess. For most South African car owners the choice comes down to two tools: the CRP123X Plus and the CRP129X Plus.
Both are 5-inch Android handhelds that plug into your vehicle's OBD2 port, read and clear fault codes and show live data. The difference is how far they go beyond the engine, and whether you also want to do your own service resets at home.
Who the CRP123X Plus is for
The LAUNCH CRP123X Plus is the lower-cost of the two. It reads and clears diagnostic trouble codes, identifies engine faults and shows a live data stream so you can see what the sensors are doing. It comes with free lifetime software updates, which keeps it current as newer models arrive. Hardware includes a 5-inch 720p screen, Android 7.0, a 6000mAh battery, 2GB plus 16GB of storage and 2.4GHz Wi-Fi.
It suits a car owner who mainly wants to know why a warning light is on, check whether a fault is serious, and walk into a workshop already knowing the code instead of paying for a diagnosis first.
Who the CRP129X Plus is for
The LAUNCH CRP129X Plus V3 scans all systems, not just the engine. That includes ABS, steering angle (SAS), transmission, body, TPMS, immobiliser and airbag (SRS) modules. It also adds eight service and maintenance functions:
- Oil service reset
- Throttle matching
- Steering angle (SAS) reset
- Brake pad reset
- DPF regeneration
- Injector coding
- Battery monitoring (BMS) reset after a new battery
- TPMS reset
It has Auto VIN to identify the vehicle automatically, a built-in code search with repair tips, diagnostic reports you can save and share, and a battery check that shows real-time voltage as a waveform chart. Updates come over Wi-Fi every week, and the product page lists two years of free updates.
Which one makes sense in South Africa?
Think about what you actually do with your vehicle:
- You want to read the check engine light and nothing more. The CRP123X Plus covers that and keeps updating for life.
- You do your own oil changes, brake pads or battery swaps. The CRP129X Plus lets you reset the oil light, brake pad warning and battery monitor yourself, instead of driving to a workshop just to switch off a light.
- You run a diesel bakkie or SUV. The CRP129X Plus includes DPF regeneration and injector coding, which the CRP123X Plus page does not list.
- You have an ABS, airbag or tyre pressure light on. Those sit outside the engine, so you need the all-systems coverage of the CRP129X Plus.
The CRP129X Plus product page lists support for 12V passenger cars, pickups, light-duty trucks and SUVs, and more than 85 brands including VW, Ford, Hyundai, Kia, Suzuki and Isuzu. Coverage still depends on your exact make, model and year, so check before you buy.

Questions we get asked
What is the difference between the LAUNCH CRP123X Plus and CRP129X Plus?
Both read and clear fault codes and show live data. The CRP129X Plus V3 scans all systems, including ABS, airbag, TPMS and immobiliser, and adds eight service resets such as oil, brake pad, battery and DPF.
Which LAUNCH scanner is best for a home mechanic in South Africa?
If you only want to read the check engine light, the CRP123X Plus is enough. If you do your own oil changes, brake pads or battery swaps, the CRP129X Plus lets you reset those warning lights yourself.
Can the CRP129X Plus do DPF regeneration on a diesel bakkie?
DPF regeneration is one of its eight listed reset functions, alongside injector coding. Support depends on your exact vehicle, so check your VIN with the Launch Dealer SA team first.
Does the CRP123X Plus get software updates?
Yes. The CRP123X Plus comes with free lifetime software updates to keep up with newer vehicle models.
