This Ford OBD1 scanner has a built-in memory for storing codes. In case the MIL is on, once you’ve fixed the identified issues, the Innova 3145 will switch it off. The OBD1 code reader will tell you exactly what problems your vehicle’s engine has. With Innova 3145, you can retrieve engine and transmission trouble codes. The scanner diagnoses Ford’s EEC-IV and MCU systems. While it covers Ford cars and trucks, the cars in question should not be more than one ton heavy. Innova 3145 OBD1 code reader works on most Ford vehicles between 19, including Lincoln and Mercury. Either way, once the issues are gone, the CEL will turn off. Obviously, it all depends on the nature of the problem. From there, you can either fix it yourself or take it to a repair shop. After that, refer to the guidebook for the definitions to understand what each code means.īasically, the information you will get is a report of what’s wrong with your vehicle’s engine. Just use this OBD1 scanner to retrieve all the DTC codes. So once the Check Engine Light (CEL/MIL) comes on, you can perform a DIY diagnosis yourself. The good news is that this OBD1 scanner comes with a guidebook that contains definitions of DTC codes. If you’re not a mechanic, you probably won’t understand what each code means. The dimensions of 10 x 2 x 6 inches make it compact enough to fit in your vehicle’s compartment. If you have this GM OBD1 scanner with you, it will only take a few minutes to retrieve the DTC codes and understand the problem. This OBD1 code reader reads ECM (engine) and ABS (anti-lock braking system) codes.

More specifically, it covers US GM cars and trucks between 19. This OBD1 scanner accesses your vehicle’s onboard computer systems and retrieves trouble codes. It is capable of communicating over all of these OBD2 protocols, and using one of the many diagnostic softwares available allows the backyard mechanic grab diagnose any engine related problems.The Innova 3123 is designed to work on most OBD1 GM vehicles. The most common scantool for this job is the ELM327 cable as pictured to the right. OBD2 Cables main use is for looking up diagnostic trouble codes,history fault information and also viewing live engine data. So technically, ALDL, VPW and CAN are all different protocols, that speak different languages and all have there specific functions. This means theres a whole heap of available information,software and knowledge on the web as this standardized protocol is widely used,reversed and developed around the world. Looking specifically at the commodores, the OBD2 protocols that GM uses is VPW and CAN protocols. All models and manufactures must meet the bare minimum criteria which includes looking up fault data, engine data and other diagnostic information. OBD2 has a major difference in the interpreting of this data compared to ALDL, its all standardized therefore it is very simple to understand.

But in fact, theres a whole heap of OBD2 lanaguages, think of it as being able to speak English with a different accent, it sounds similar but isnt quite the same. OBD2 is the “Generic” name for this communication language.
ALDL CODE READER SOFTWARE
So why is this important? Imagine 20 people all trying to speak at once, it would feel pretty crowded and “noisey” wouldnt it? Meaning that alot of information is being passed all time so any software developed for ALDL cables needs to be efficient and effective to be able to keep up the the busy line! This information is sent out in an orderly fashion that all the cars electronics can see, It is mainly directed at the BCM (Body Control Module) since it is the BUS master which looks for all the other modules signals to ensure all components are working correctly.Įnough about the modules, looking more into the inner workings of an ALDL Cable, the information obtained from the car is fed directly through the ALDL cables chip and the raw data is passed onto the computer. Specifically looking at Holden Commodores, VR to VZ Commodores use this Protocol to communicate been majority of the cars electronics to pass important information and status’s ranging from seat-belt status all the way to airbag deployment. This protocol is”non standardized” meaning GM implemented a communication protocol that is not be exactly the same as any other vehicle let alone any other manufactures.

Starting with ALDL cables (Also know as OBD1 or GM OBD), these types of cables communicate over a very basic protocol.
