PINPOINT TEST J : U2003: COMPACT DISC CHANGER NOT RESPONDING

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. Failure to follow this instruction may result in damage to the vehicle.
• NOTE: The following test sequence is based on a five node network. Refer to the wiring diagrams for network configuration for networks
with a diferent number of nodes (all possible network combinations are shown in the wiring diagrams).
• 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). GO to Pinpoint Test

PINPOINT TEST K : ONE OR MORE D2B MODULES NOT RESPONDING. 'WAKE-UP' SIGNAL FAULT

• NOTE: The D2B 'wake-up' signal is not a constant, but will generate a pulse at each cycle of the ignition key. The ignition key must be
turned to the OFF position following each step of the tests, and turned to the position indicated by the test step for each module. To avoid
missing the signal, use an assistant to operate the key while reading the oscilloscope. The 'wake-up' line is battery voltage, switching to 0
volts for between 50 milliseconds and 110 milliseconds as the ICE head unit sends it's signal.
