Pinpoint Test X: U2003: COMPACT DISC CHANGER NOT RESPONDING

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Jaguar S-Type, 2007 Jaguar S-Type, 2006 Jaguar S-Type, 2005 Jaguar S-Type, and 2004 Jaguar S-Type. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: The following tests involve disconnection of the fibre optic harnesses. The harness connectors must be protected by suitable dust caps as soon as they are disconnected, or damage may result. The use of tools to unlatch connectors must be avoided, or the connector locking function may be lost.

NOTE: The following test sequence is based on a six node network. Refer to the electrical guide for network configuration for networks with less nodes. (all possible network combinations are shown in the electrical guide)

NOTE: should a break occur in the D2B ring, then codes, U2602, or U2603 will be set, depending on the location of the break. U2602 will set if the break is in the optical harness FROM the ICE head unit, (the transmitter signal) U2603 will set if the break is in the optical harness TO the ICE head unit, (the receiver signal).
