Porsche Boxster (987), Cayman, and 911 (997) Troubleshooting

Be sure there are no fault codes in the engine, instrument cluster, ABS, or airbag units. Durametric version must be 5.0.8.0 or higher. If the instrument cluster does not reset automatically when resetting the service reminder, remove the instrument cluster fuse for ten seconds with the key out before replacing the fuse.

These newer cars use the CAN bus for diagnostics. The CAN bus will go into sleep mode after only a few minutes if the car's engine is not running. To prevent this, you can either start the car's engine (when it's safe to do so) or turn on the hazard light (emergency flashers) just after turning on the car's ignition.

When activating drive links you may receive the message in the status bar that reads "Conditions are not correct". This is the response from the control module indicating that some other conditions need to be met before the drive link can be carried out. For example, some drive links may require a specific operating temperature or a specific RPM. These conditions can be found in the factory manual.

Diagnostic communication to these units is managed through a gateway. The instrument cluster in the 987/997 doubles as the gateway and often must be reset to restore communication to those units. To reset, remove the instrument cluster fuse for 10 seconds with the key out.

Durametric is capable of displaying the engine over-rev information. On the 987 and 997, this is broken into six categories: ranges 1 - 6.

• Range 1 - 7200-7500 (7300 - 7500 for 911)
• Range 2 - 7500-7700
• Range 3 - 7700-7900
• Range 4 - 7900-8400
• Range 5 - 8400-9500
• Range 6 - 9500 and up. This occurs when the engine is mechanically over-revved by shifting into a lower gear and mechanically exceeding the rev-limiter.

The number shown is each spark ignition over the rev-limiter. The hours displayed next to each range value is the number of operating hours when the last ignition occurred.
