Frequently Asked Questions

Program-related Questions

Why should I enroll in this program?

Typically, the estimated cost of downtime for a heavy-duty vehicle is approximately $800 USD for every nine hours. Additionally, pulling medium or large fleet vehicles into a workshop to perform Periodic Smoke Opacity Tests or scanning the ECU with laptop diagnostic tools for compliance with this program has significant administrative overhead. The alternative solution is to outsource to someone with equivalent hardware.

When enrolled in this program, Geotab will provide significant time and cost savings to ensure the process is smooth.

How much will this product cost from Geotab?

The use of this product is available for any device on the GO Plan or ProPlus plan.

Is Geotab certified?

Yes, Geotab was certified on November 21st, 2024. CARB site / EO.

When will the CARB Clean Truck Check Program begin?

The periodic testing requirements will begin on January 1, 2025. The earliest date a fleet owner can submit a Clean Truck Check on-board diagnostics (OBD) scan is October 1, 2024.

Prior to January 1, 2025, fleet owners are required to register their regulated vehicles in the program using the CARB CTC-VIS portal, and clear any registration holds issued due to missing the 2023 registration deadline.

Who is regulated by the CARB Clean Truck Check program?

This regulation is applicable to the 1.2 million heavy-duty vehicles operating in or passing through the state of California. In this context, a heavy-duty vehicle refers to diesel vehicles from 2013 or newer, and alternative fuel or hybrid vehicles from 2018 or newer — with Gross Vehicle Weight Rating (GVWR) of 14, 001 lbs or more.

For more information, refer to the CARB Clean Truck Check Program document.

What data is collected and reported?

The GO device functions as a diagnostic tool connected to the OBD port, and collects the following data:

1. Freeze frame data
2. Streaming data parameters
3. Fault codes (including Active, Pending, and Permanent)
4. Vehicle Identification Number (VIN)
5. Engine serial number
6. Engine family
7. Electronic Control Unit (ECU) number
8. Monitor use performance ratio
9. Engine run time tracking data
10. NOx emissions tracking data
11. Greenhouse Gas (GHG) tracking data
12. PM filter regeneration event data
13. Readiness status of each monitor within a readiness group

How often will collected data be submitted to CARB?

Geotab collects vehicle data at the frequency configured by the customer during the asset enrollment process in the MyGeotab portal. This data is submitted to CARB continuously until a passing result is achieved. Once a passing result is obtained, Geotab will only submit data collected when the next compliance window opens up.

How often is a passing submission required?

Fleet owners are required to report to CARB one compliant submission per reporting period: once in 2024, twice a year in 2025 and 2026, and four times a year in 2027.

How is a pass or fail determined?

The criteria for determining a pass or fail have not been explicitly provided by CARB. Geotab is inferring that any Diagnostic Trouble Code (DTC) that may activate the Malfunction Indicator Lamp (MIL) will cause a failing submission

Where can I find the specific reason my asset failed a scan?

You can use the DTC/Fault codes reports on MyGeotab to see some of the reasons that would contribute to a failed scan. CARB does not currently provide this functionality.

Additional regulation-specific nomenclature can be located in “2195.1. Definitions” in Attachment A-1 Final Regulation Order and “PART 1: Definitions” in Attachment B: California Standards for Heavy-Duty Remote On-Board.

Hardware-related Questions

Will using the OBD port void my warranty?

No, under the Magnuson-Moss Warranty Act in the United States, vehicle manufacturers cannot void warranties based on the utilization of aftermarket telematics devices, such as OBD diagnostic tools provided by the Geotab GO device.

However, when evaluating a new or current Geotab GO device installation, it's essential to consider the advantages and compliance offered through the CARB Clean Truck Check Program — previously known as the Heavy Duty Inspection & Maintenance Program. The Geotab GO device, in conjunction with the OBD port, provides a seamless solution to achieve optimal fleet performance and environmental compliance.

For over two decades, the OBD port has remained the industry benchmark to grant vehicle owners, technicians, and service providers dependable access to crucial diagnostic and monitoring data. The compatibility of the OBD port with an extensive range of vehicles ensures that diagnostic tools and equipment can be effectively utilized across various makes and models.

As mandated by the CARB Clean Truck Check Program, the OBD port is essential for confirming that your vehicles comply with environmental standards.

The use of the OBD port for diagnostics, maintenance, and repairs with the Geotab GO device will not jeopardize the vehicle warranty. Under the Magnuson-Moss Warranty Act in the United States, vehicle manufacturers cannot void warranties based on the utilization of aftermarket telematics devices, such as the OBD diagnostic tools provided by the Geotab GO device. For more information, refer to section six of the Geotab OBD FAQ.

Which devices are certified?

Geotab’s GO9, GO9+, and GO9B devices. You can see the list of certified Geotab devices here.

Can a fleet plug in a Camera provider's 9-pin T-harness to a Geotab T-harness for power, is the vehicle still CARB compliant?

No, based on the latest CARB's EO, only a combination of the below HW is compliant. Any additional harnesses going in-between would render the configuration non-compliant. Below are the full harnesses that may be used.

What harnesses can I use to fulfill this requirement?

Our CARB-compliant aftermarket telematics solution includes the required combination of the following elements:

1. One of the following GO devices:
2. 1. GO9^®
   2. GO9B^®
   3. GO9+^®
   4. GO9 Rugged^® device
2. One of the following T-harnesses:
3. 1. HRN-GS09K2
   2. HRN-GS09K2-A
   3. HRN-GS16K22
   4. HRN-GS16K22-A
   5. HRN-GR09K1
   6. HRN-GR09K1-A
   7. HRN-BD16S5
3. A CARB EO label, which needs to be applied under the hood. The installation instructions accompanying the label describe the appropriate installation location where it should be affixed in the vehicle.

The solution was developed to address the following CARB requirements:

1. No changes or alterations done to the CARB-approved OEM emissions control system, including the on-board diagnostic (OBD) system.
2. T-harnesses (HRN-GS16 and HRN-GR09 SKUs) will not be made available without dust-caps, as required by state law.

A CARB-compliant sticker must be located within the engine compartment of the vehicle.

What ports should I use to install my GO device for CARB-compliance?

The physical interface is for the OBDII Port only. ✱ NOTE: The data obtained from the RP1226 port is not compliant with the CARB Clean Truck Check Program.

GO devices installed to RP1226 will not be able to collect the required data for the following reasons:

1. The RP1226 port is not a CARB-regulated diagnostic port, and thus any enforcement action cannot be taken based on that data.
2. The RP1226 port often only provides broadcast data, while the Clean Truck Check program requires both broadcast and targeted data.
3. The RP1226 port often has a gateway through which an OEM filters the data available to the diagnostic tool.
4. The OBDII is stated to be the only method in which data can be collected for the use of Clean Truck Check compliance.

If an Original Equipment Manufacturer (OEM) would like to pursue compliance through the RP1226 port, they will need to discuss with CARB directly.

GO devices installed using the CAN bus direct wire installation cannot be used to be compliant with the Clean Truck Check Solution as seen in §E.1.2 of Appendix B in the regulations.

MyGeotab or Feature-related Questions
