How do I read the trouble codes? Do I need an external reader? I notice that several of them use a database starting with 1996. I am specifically needing to read the transmission codes. Thanks

No, the ZURICH ZR4s OBD2 Code Reader is primarily used for reading and clearing diagnostic trouble codes (DTCs) from the vehicle's onboard computer system. It does not have the capability to relearn or reset specific sensors such as the crankshaft position sensor. Sensor relearning typically requires specialized tools or software that are specific to the vehicle manufacturer.
There are trouble codes listed for your wipers. Did you check for codes? My database shows B type codes. Check for manufacturer specific codes. There are code readers that will check manufacturer specific codes as well as po codes. https://ibb.co/mQCyqf
Click on the link, that is one of the possible codes listed for wipers. There are several.
Check for applicable trouble codes? To check codes yourself, at the least, you need an obd2 code reader. Some of the national brand auto stores will check po codes for free. I don't know if they will check manufacturer specific codes?
Does it start and run ok? How long since a tune-up?
year vehicle manufactured? if 1996 & later, OBDII scanner to be plugged into a port (typically, should be near the steering column, under the dash).
older models may have OBDI (no standard location of port) scanner specific to the make of the vehicle. search the web, on how to read manually (or without scanner) the code by counting the number of blinks of the MIL (malfunction Indicator light) (aka check engine, or service engine soon).
Not yet. The check engine light coming on is letting you know that the self diagnostic function of the engine computer has detected a problem and set a trouble code. That code can be read by a code reader. Most major auto parts stores have these code readers and will read your code for free. The code number can tell you/us where to start looking for the problem.
Did you charge the battery after replacing the alternator? Is the check engine light on? If so, rent a code scanner and read out any trouble codes. That should point you in the general and maybe specific direction to help track down the problem. Hope this helps!
Are there any trouble codes stored in the computers memory? A code reader will allow you to read trouble codes if any exist. This is the first place any tech would start a diagnosis, otherwise we will only be guessing a repair solution.
