The Data Bus On Board Diagnostic Interface -<br />

J533- (which is integrated into the instrument<br />

cluster) enables data to be exchanged between<br />

the "Powertrain" CAN Data-Bus network and the<br />

Data Link Connector (DLC) "K-wire".<br />

The Data Bus On Board Diagnostic Interface -<br />

J533- has specific On Board Diagnostic (OBD)<br />

capabilities.<br />

Before performing any troubleshooting or<br />

inspection, always begin by checking for DTCs<br />

using the OBD program. DTCs stored in memory<br />

are retrieved/checked with either the VAG<br />

1551/1552 Scan Tool (ST) or VAS 5051 Vehicle<br />

Diagnostic Tester.<br />

Notes on exchanging instrument cluster<br />

Do not disassemble instrument cluster.<br />

Instrument clusters contain no field serviceable<br />

components. All malfunctions require<br />

replacement of instrument cluster.<br />

When the replacement of a malfunctioning<br />

instrument cluster is necessary, follow<br />

exchange part procedures.<br />

Complete the report form and return together<br />

with instrument cluster.<br />

Use the original packaging from the new cluster<br />

when returning modules.<br />
