Why your exact configuration matters

The same model can follow different maintenance rules depending on year, powertrain, drivetrain, mileage, and driving conditions.

Example configuration comparison

Same model. Different applicable rules.

This preview shows how the interface explains configuration differences without guessing or merging incompatible schedules.

Schedules are resolved from the rules that apply to the selected vehicle configuration. The final site should never infer missing applicability.

How we verify a maintenance schedule

Every published schedule should trace back to manufacturer documentation, preserve the conditions that change the rule, and pass review before the vehicle page goes public.

Source first. Page second. If a maintenance rule cannot be tied to a usable source and the correct vehicle configuration, it should not be published.
Source record Reviewed Vehicle applicability Rule extraction Publication check
01

Find the manufacturer record

Start with manufacturer-published maintenance documentation for the specific model year and system being covered.

02

Capture applicability

Record the year, powertrain, drivetrain, mileage trigger, time trigger, and any driving-condition qualifier that changes the rule.

03

Structure the maintenance rule

Store the action, trigger, conditions, precedence, and source reference so the interface does not have to guess what applies.

04

Review before publishing

Check source coverage, configuration logic, copy, mobile presentation, and publication requirements before a public route is enabled.

What a source record should contain

A compact example of the information kept behind a published maintenance rule.

✓ Source record
Vehicle
Exact make, model, model year, and applicable configuration
Maintenance action
The service action stated in the source record
Trigger
Mileage, time, code, monitored condition, event, or another supported trigger type
Conditions
Only the conditions explicitly supported by the documentation
Source reference
Document URL or source identifier, relevant location, and verification date
Publication status
Draft until the record passes the required review checks

Not every vehicle uses the same maintenance system

Some vehicles follow fixed intervals. Others use dashboard codes, monitored conditions, or a mix of systems. The page should match the way the manufacturer actually defines maintenance.

One template should not force every vehicle into the same type of schedule.
Fixed interval

Mileage and time schedules

Used when maintenance is defined by recurring mileage, time, or specific milestone triggers.

TriggerMileage / time
Primary viewTimeline
User seesDue now + next up
Code based

Maintenance code systems

Used when the vehicle reports maintenance through dashboard codes or manufacturer-defined service indicators.

Example displayA1

Condition based

Monitored-condition maintenance

Used when service depends on vehicle monitoring, operating conditions, wear, or another supported condition instead of one fixed interval.

Combined maintenance logic

Used when one vehicle combines fixed intervals, codes, milestones, and condition-specific rules in the same schedule.

The interface follows the maintenance system

The data model determines what the page renders. The page should not invent a single timeline when the manufacturer uses another system.

The final product should choose the page structure from verified vehicle data. It should never assign a maintenance system from appearance, brand, or guesswork.
