ALP 2No topology diagram or configuration table display at the end of
the multiplex network test
The topology cannot be displayed under the following conditions:
1. The two computers storing the multiplex network configuration have failed to respond.
2. The multiplex network is not operational; therefore dialogue is impossible.
3. The two computers storing the multiplex network configuration do not have the same configurations.
4. On the Multiplex network tab on the configuration screen, an incorrect Diagram version number has been
entered into one of the two computers that store the network configuration.
5. No Network version has been entered into the two computers that store the configuration.
1 –
Vehicle multiplex network
The two computers storing the multiplex network configuration did not respond.
Check first that the computers storing the configuration (Airbag and UCH) are correctly supplied:
–check for earth on connection NAP, and for +12 V supply on connection AP25 on component 756.
–check for earth on connections MAM and NAM, and for +12 V supply on connections AP7, AP43, BP3, BP6,
BP15, BP19, BP49 on component 645.
Check the condition of the multiplex network and the continuity and insulation of the CAN H and CAN L lines
between the computers storing the configuration.
Multimedia multiplex network
The computer containing the multiplex network configuration did not respond.
Check first that the computer storing the configuration (A2/A3 display) is correctly supplied:
check for earth on connection NAM, and for +12 V supply on connection BCP4 and BPT to the display 653.
Check the condition of the multiplex network and the continuity and insulation of the CAN H and CAN L lines
between the computers storing the configuration.
2 – The multiplex network is not operational, therefore dialogue is impossible
(see fault "Multiplex network not operational").
3 – The computers storing the multiplex network configuration do not have the same configurations
(see configuration "Multiplex network configurations").
4 –On the multiplex network tab of the configuration screen, an incorrect diagram version number has
been entered on one of the two computers storing the network configuration
(see configuration "Network configuration").
5 – No diagram version has been entered on the two computers storing the configuration.
(see configuration "Network configuration").
