CARB Certified Clean Truck Check Compliance

ES LATAM

November 2024

Introduction

This document provides detailed information about the Clean Truck Check program implemented by the California Air Resources Board (CARB). This program aims to regulate the approximately 1.2 million heavy-duty vehicles operating in or passing through California to ensure compliance with environmental standards.

Geotab has certified the GO9 product family to complete the data submission and collection process. The GO device acts as a diagnostic tool connected to the vehicle’s OBD port. The diagnostic data is then uploaded to the CARB servers to inform compliance status based on the requirements set out in the legislation (see useful resources).

In this manual, you will find comprehensive explanations about program requirements, data collection and reporting, pass/fail determination, enrollment procedures, hardware compatibility, and features within the MyGeotab platform. Whether you are a fleet owner, reseller, or customer, this manual will guide you through the necessary steps to successfully participate in the program and leverage Geotab's solution.

Please read through this user manual to gain a comprehensive understanding of the CARB Clean Truck Program and make the most of the provided information and features.

References to fill:

For complete definitions and applicability, refer to the linked regulation. For details on registering on the Clean Truck Check-Vehicle Inspection System (CTC-VIS).

Periodic testing requirements

The passing test must be submitted within 90 days before compliance test deadlines, which are based on DMV registration dates for California registered vehicles, and based on the last digit of the VIN for non-California registered vehicles​.

! IMPORTANT: Geotab does not support non-OBD-equipped vehicles and pre-2013 model year vehicles.

Pre-2013 model year engines

1. Non-OBD equipped vehicles must submit to opacity tests and visual/functional inspections twice per year.
2. California motorhomes and on-road agricultural (AG) vehicles must test once per year.

2013+ model year engines

1. OBD-equipped vehicles must submit to OBD tests twice per year, for 3 years.
2. After those 3 years, OBD tests must be performed four times per year.
3. California motorhomes and on-road agricultural (AG) Vehicles must test once per year.

Testing types

OBD-equipped vehicles must provide a data submission. The Geotab GO9 product family is certified to collect and submit this data.

Collected data

The following data parameters are collected and submitted:

1. Freeze frame data
2. Streaming data parameters
3. Fault codes including active, pending, and permanent
4. VIN
5. Engine serial number
6. Engine family
7. ECU name
8. Monitor in use performance ratio
9. Engine run time tracking data
10. NOx emissions tracking data
11. GHG tracking data
12. PM filter regeneration event data
13. Readiness status of each monitor within a readiness group

14. The specific data that is collected, categorized by OBD protocol, is described in Appendix B of the regulation.

15. Data collection and submission process

16. Geotab’s GO9 Device records data from the vehicle and brings this data into the Geotab environment. MyGeotab houses all this raw data in a binary format. A Web Service Middleware, created specifically for this integration, requests this data from MyGeotab, formats it in an .xml and .csv format specified, and then sends this data in encrypted format to CARB servers.

17. GO Device → MyGeotab → CARB

18. The data collection process occurs while the vehicle is not moving on the first Ignition ON event after a new installation, and every 7 days thereafter.

19. ✱ NOTE: A complete data collection process can take up to 2 minutes. Moving the vehicle will interrupt the collection process.

20. While in cellular coverage, the submission process happens immediately as soon as the data is available. While out of cellular coverage, the GO device stores up to 15 complete submission files on the device until cellular coverage is restored.

21. Compliance pass/fail determination

22. From the 2196.3 - (c) of the final regulation order, a submission is considered compliant if none of the following conditions occur:

14. The vehicle’s OBD system reports the MIL as commanded on;
15. The vehicle’s OBD system reports an active or permanent diagnostic trouble code (DTC);
16. The vehicle’s OBD data indicates the OBD system has not yet operated sufficiently to determine the presence or absence of a DTC;
17. The vehicle’s OBD data collected during a compliance test is inconsistent with the OBD data profile from vehicles with the same make, or model year generated using all valid compliance test records submitted to the Executive Officer;
18. The OBD system data does not match the original equipment manufacturer (OEM) or a CARB-exempted OBD software configuration. The OBD software configuration shall include the specific OBD standard to which the vehicle has been certified, the Calibration Verification Number(s) (CVN), and the Calibration Identification Number(s) (Cal ID); or
19. The test submission does not meet the requirements specified in section 2196.3(a) or (b).

Data retention

All data collected for the use of CARB Clean Truck Check follows Geotab’s data retention policy for a maximum of 10 years for monthly database snapshots.

Using the product

Prerequisites

Rate Plan verification

Ensure that the GO devices to be installed in the target vehicles are on the ProPlus or GO plan.

Device installation and verification

Ensure that the GO device is installed appropriately into the target heavy-duty vehicle by following the outlined steps here. It is required that the GO device is installed on the OBD port rather than any other diagnostic port (i.e. RP1226).

Geotab CARB-compliant solution

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

1. Either a GO9^®, GO9B^®, GO9+^® or 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 must be applied under the hood. The installation instructions accompanying the label describe the appropriate location where it should be affixed in the vehicle as shown below:

This solution was developed to specifically address the following CARB requirements:

1. No changes or alterations done to the CARB-approved OEM emissions controls system, including the on-board diagnostic (OBD) system.
2. T-harnesses (HRN-GS16 and HRN-GR09 SKUs) will now be made available with no dust-caps, as required by state law.

A CARB-compliant sticker is to be located within the engine compartment of the vehicle as shown above.

MyGeotab software version

Ensure that the MyGeotab database to which the GO device is associated is on version 11.0 or newer.

Geotab GO device firmware version

Ensure that the GO device’s firmware version is 40.36 or newer.

Reviewing submissions

There are four key information columns on the Clean Truck Check Program page.

1. The Asset column refers to the asset’s given name. You can click an asset to open its corresponding Asset Details page.
2. The Status column refers to the state of the asset in terms of compliance with the Clean Truck Check program. The test results received from CARB are displayed here.
3. 1. A status ofdenotes a successful test and no further action is required.
   2. For details of other test result statuses, please check your CTC-VIS account for details and instructions.
3. The Last submission date column refers to the most recent date that the asset submitted data to the CARB platform.
4. The Next compliant deadline column refers to the next date before which a passing submission is required. It is determined by the vehicle’s compliance deadline, associated with its compliance year. Semiannual deadlines occur on a vehicle’s compliance year expiration day, six and twelve months after that day.
5. 1. For vehicles registered in the state of California, the Next submission date aligns with the day and month of the vehicle’s DMV registration expiration date.
   2. 1. https://ww2.arb.ca.gov/overview-fact-sheet-clean-truck-check
   1. For non-California registered vehicles, and for vehicles exempt from DMV registration, the compliance year begins and ends on the last day of the month specified below, based on the last digit of the vehicle’s VIN.
