I have a CRP123, and cannot read my air bag (srs), ABS, or transmission codes on my truck. The airbag light is on... It's a 1998 Dodge Ram 1500. Does this scanner not support this vehicle? I also can't read any system on my 1997 Nissan Hardbody D21 Pickup. And even though listed as a compatible vehicle... my dad's 1995 buick 4th VIN "C" with a 3.8l v6 with a 16pin OBD2 connector does not work either. What do I do?
I just bought it and just updated the CRP123.
Diagnostic library/programs version V11.22
My CRP shows GM version as "GM V12.30" which seems way outdated because the compatible of GM vehicles list shows "GM V45.11" How do I get that update?
Sorry, but unfortunately as you may now realize the CRP123 does not advertise nor support any BI-DIRECTIONAL controls.
To answer your first question regarding the connection your 1998 Dodge Ram Van.
You should understand that all Chrysler vehicles from 1996- up to 2003 will require to use a special Chrysler CCD-16 pin connector in order to see the other slower speed ABS and SRS modules other than PCM module.. Our CRP123 will only show the Generic OBD2 powertrain emissions only on 96-03 year because of the standard 16-pin connection single communication speed.
In order to see other modules other than Powertrain emissions on this Chrysler ABS you must use the Chrysler CCD-16 pin connector which can only be supported on the PRO-Level scan tools with full BI-DIRECTIONAL controls.
To answer your second issue regarding the GM 1995 Buick Park Ave.
You should understand that the GM V45.11 does not apply to the CRP123 series and only applies to the Launch PRO-Level scan tools with full bi-directional controls.
You should also be aware that although this 1995 Buick Park Ave may have the OBD1.5 -16 pin connector installed at the factory BUT, it is an early production GM "JUMP AHEAD" model which GM had EPA federal government compliance to have that OBD1.5 -16 pin connector but the communication protocol (language) is NOT actually OBD2 SAE1979 compliant.
Sorry, but unfortunately the CRP123 series will NOT support any of the GM "JUMP AHEAD" OBD1.5 model vehicles. Only our Launch PRO-level scan tools systems with FULL BI-DIRECTIONAL controls will include the proper cables and adapters to view OBD1.5 vehicles and some "JUMP AHEAD" models.
And finally to answer your third issue about the 1997 Nissan D21 Hardbody pickup truck.
Our CRP123 should only be able to support the Generic OBD2 for powertrain emissions only.
If it is not able to communicate with the PCM then we my have to suggest to remove and uninstall the Nissan program V10.20 files from the micro-sd memory card and then try to download the Nissan again.
In some rare cases it may be necessary to download an older previous version of Nissan V10.00 or earlier version.
The reasons why you may not able to view or see any ABS or SRS modules on this 1997 Nissan D21 Pickup is because those slower speed modules are not wired up thru the main OBD2-16 pin connector and are actually on a different part of the Body control module and Chassis control wiring harness.
So in this rare case you may have to follow the Nissan factory service manual procedures for the ABS and SRS wiring harness connectors to jumper the correct terminal pins and put each module in BY-PASS mode to begin the FLASH READ OUT METHOD thru the ABS ans SRS MIL light on the dash.

everyone is always welcome, but to make a correction:
The DLC 16-pin connector must follow the standards set by SAE J1962. According to SAE J1962 the DLC must have a centralized location in the vehicle. It must be within 16 inches of the steering wheel. The vehicle manufacture can place the DLC in one of up to eight possible places predetermined by the federal EPA regulations.
Each pin will have have its assigned definition. Assignment of many of the pins is still left up to the manufacturer, but those pins are NOT meant to be used by the Generic OBD2 complaint control units. They can be used for SRS/RCM Air Bags, or ABS Anti-Lock Brake systems.
Just make sure to notice the connector has is own power and ground source; Pins 4 and 5 are ground and pin 16 is power. This is so that any scan tool wont require any external power source. If you plug in any scan tool and it doesnt respond, first check the pin# 16 for power and then check pins #4 and pin #5 for ground.
