Inspection and Verification

CAUTIONS:


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.


Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

1. Verify the customer concern

2. Visually inspect for obvious signs of damage and system integrity



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 the DTC Index

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

Fuses (refer to electrical guide)
Wiring harness
Correct engagement of electrical connectors
Loose or corroded connections
Routing of fibre optic harnesses
Correct engagement of optical connectors
Correct placement of optical connectors (ring order)
Correct assembly of optical connectors (backout, etc)
Damage to fibre (chafing, abrasion, kinking, cuts, etc) Visual Inspection

MOST prism. The MOST prism is connected in the same way as the MOST tester but will simply reflect any existing signal
onward to the next control module. Using the MOST prism before or after a long run of harness may cause a ring break as a
good signal may be too weak after travelling the extended distance. Also, the MOST prism will pass light in either direction so
will not detect reversed MOST terminals elsewhere in the network. For these reasons, the MOST tester is the preferred tool and
should be used unless limited access does not permit it
MOST Ring Break Indication

A ring break in the MOST network is indicated by a blank touch screen display if the break is before the touch screen display or
a flashing logo of the break is after the touch screen display. Possible causes of ring breaks are listed in the symptom chart

CAUTIONS:


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


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 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


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


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


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If diagnostic trouble codes 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


Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required
