Perform an immediate assessment

Expected result

Important notes / prerequisites

Sign in with the applicable Immediate Assessment subscription and use a supported datalink adapter. Available functions depend on your subscription entitlement, connected equipment, and supported fault or calibration data.

For a new assessment, select the Immediate Assessment seat during login to display New Assessment on Home. To start from an appointment, your account must be enabled in Guidanz Service Event Management and the pending service request must already exist there.

Internet access is required to retrieve the manufacturer and model list using the confirmed ESN. Correct make and model information improves estimated repair-time accuracy compared with an accessibility code.

Creating a service request requires the applicable Service Event Management access and an active assessment or connection context.

Start a new assessment

2. From Home, select New Assessment.
3. Connect to the engine through the selected datalink adapter, then complete Intake.

Start from a pending service request

Pending service requests are created in Guidanz Service Event Management.

1. From Home, select Pending Service Requests to open the Schedule page.
2. Review appointments for Yesterday, Today, or Tomorrow and select the correct appointment.
3. On the appointment screen, select Perform Immediate Assessment.
4. Connect through the selected datalink adapter and complete Intake.

Complete Intake

1. Review the vehicle information, Engine Serial Number (ESN), and customer name retrieved during Intake. Correct any inaccurate information.
2. Using the confirmed ESN, Guidanz retrieves the equipment manufacturer and model list from the server. It pre-selects information from warranty data and the ECM when available; confirm or correct the selection.
3. If you select Other, select an accessibility code when prompted. Use the correct make and model whenever available for more accurate estimated repair times.
4. Complete Intake and review Faults and Analysis.

If no manufacturer list appears, possible causes include no data for the supplied ESN, no internet connection, or a server issue.

Severity codes

The Faults and Analysis screen displays the overall severity code for the engine. Each severity uses a specific strip color and icon.

Prioritized faults

Primary faults are critical faults that should be repaired first. Resolving a primary fault will often also resolve secondary faults. Review the prioritized Cummins fault codes, descriptions, and top three most likely root causes.

Scan Faults is a separate focused function for reading engine faults without fault prioritization.

Estimated service times

After the assessment, service-time estimates based on historical data are displayed only for fault codes that support an estimate. Confirm the correct equipment make and model during Intake to improve accuracy.

Create a Service Request

1. Complete the Immediate Assessment on the new engine and review the results.
2. Open Event from the top toolbar, then select Create Service Request.
3. Complete the requested service-request information and submit it to create a Guidanz Service Event Management service request.
