Safety Information

WARNINGS:


The Xenon Headlamp system generates up to 28,000 volts. Make sure that the headlamps are switched off before
working on the system. Failure to follow this instruction may lead to fatality.

The following safety precautions must be followed when working on the Xenon Headlamp system:
DO NOT attempt any procedures on the Xenon Headlamps or circuits when the system is energized.
Handling of the xenon bulb must be performed using suitable protective equipment, e.g. gloves and goggles. The glass
part of the bulb must not be touched.
Only operate the lamp in a mounted condition in the reflector.
All safety procedures and precautions must be followed to prevent personal injury.


CAUTION: Xenon bulbs must be disposed of as hazardous waste.

There are instructions on the correct procedures for Xenon Headlamp System repairs in the manual, refer to section 100-00 -
General Information, Standard Workshop Practices of the workshop manual.

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.

2. Visually inspect for obvious signs of damage.



3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to DTC Index.

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

H. Controller Area Network (CAN)

Control Module Connections to the CAN Harness

Control modules are connected to the CAN harness either in a 'loop' or 'spur' configuration. In the 'loop' type configuration the
CAN harness loops into the module (via two connector pins) and then loops out of the module (via another two connector
pins). In the 'spur' type configuration, a harness spur is spliced into the main 'backbone' of the CAN harness and the module is
connected to the harness spur via two connector pins. Electrical

CAN Harness Architecture

For a detailed description of the CAN Networks and architecture, refer to the relevant Description and Operation section in the
Workshop Manual.
CAN Network Integrity Tests

If a control module is suspected of non-communication, the Network Integrity test application available on the manufacturer
approved diagnostic system can be used to confirm if communication is possible between the control modules on the vehicle
and the manufacturer approved diagnostic system (via the J1962 diagnostic connector ). The results from the test can be used
to determine if either a single module or multiple modules are failing to communicate.
CAN Terminating Modules

If the Network Integrity test indicates that one or more module on one of the CAN networks (HS or MS) are failing to
communicate, there are several checks that can be made. The first step is to identify if both of the CAN terminating modules
on each individual CAN Bus are communicating. If both CAN terminating modules for each individual CAN Bus are
communicating (identified via the Network Integrity test), then it can be confirmed that the main 'backbone' of the CAN
harness is complete. The main 'backbone' of the CAN harness consists of all the modules connected to the CAN harness via a
'loop' configuration and also includes the two terminating modules.

Communication with both CAN terminating modules via the Network Integrity test confirms the physical integrity of the main
'backbone' of the CAN harness (and the harness spur to the J1962 diagnostic connector). This means that there is no
requirement to check the resistance of the CAN Network. This is because the standard check for 60 ohms across the CAN High
and CAN Low lines will not provide any additional information regarding the physical condition of the CAN harness, beyond
what has already been determined from the Network Integrity test.
Non-Communication of a Terminating Module

If a Network Integrity test reveals a terminating module is failing to communicate it can indicate a break in the main
'backbone' of the CAN harness. The first checks should always be to confirm the power and ground supplies to the
non-communicating module are correct. Providing these are correct, the resistance between the CAN High and CAN Low lines at
the J1962 connector can be checked to determine the integrity of the main 'backbone' of the CAN harness. After disconnecting
the battery a reading of 120 ohms would indicate an open circuit in the main 'backbone' of the CAN harness. Alternatively, a
reading of 60 ohms would indicate that there is no open circuit fault with the main 'backbone' of the CAN harness.

It is worth noting that even if one of the terminating modules is disconnected from the CAN harness, communications between
the modules still connected may still be possible. Therefore communication between the manufacturer approved diagnostic
system and the connected modules may also be possible.
Locating CAN Harness Open Circuits

In the case where multiple modules, including a terminating module, are failing to communicate, having first confirmed the
power and ground supplies are correct, the approximate location of the open circuit can be identified from analysis of the
Network Integrity test results and reference to the relevant CAN network circuit diagrams. For example, if an open circuit
existed in a certain position on the CAN harness, any module positioned on the Network between the J1962 connector and the
open circuit should return a response during the Network Integrity test. No responses would be returned from any modules
past the open circuit fault in the Network.
CAN Harness 'Spur' Type Configuration Circuits

If, after the initial checks (Network Integrity test using the manufacturer approved diagnostic system, and power and ground
supplies to the module have been checked and confirmed as correct), a module that is connected to the CAN harness via a
'spur' type configuration is suspected of not communicating, then the physical integrity of the CAN harness 'spur' can be
checked.

This is most easily undertaken by individually checking the continuity of the CAN High and CAN Low lines between the
non-communicating module connector (with the module disconnected) and the J1962 diagnostic connector.
'Lost Communications' DTCs

As well as the methods described so far in this document, which can be used to determine the location of an open circuit in
the CAN harness, 'Lost Communications' DTCs can also be used for this purpose. Lost communication DTCs mean that a
module is not receiving CAN information from another module.

For example, if a global DTC read were to be carried out, only DTCs stored in the modules that the manufacturer approved
diagnostic system could communicate with would be displayed. If there was an open circuit fault in a certain position on the
CAN harness, the modules that could display DTCs would all be prior to the open circuit on the Network, and these modules
should display 'Lost Communications' DTCs with all the modules located on the Network past the open circuit fault.
'Bus off' DTCs
The references to bus and its condition refer to the network concerned and the modules on that network.

If a module logs a 'Bus Off' DTC, it means that the module has detected CAN transmission errors and has disabled it's own
CAN transmissions and disconnected itself from the network in an attempt to allow the rest of the network to function. At this
point the 'Bus Off' DTC is set. A common cause of 'Bus Off' DTCs can be a short circuit in the CAN network.
