Multiplex Integrated Control System: Other Honda Insight ZE2 рестайлинг

Using the HDS (Preferred method)

Connect the HDS to the Data Link Connector (DLC).

Note. There are two ways to read B-CAN code with the HDS.

First method: On the HDS, select BODY ELECTRICAL, then select the subsystem that relates to the problem (for example: door locks, keyless, security, ets.), and then last, select the DTCs.

Second method: Ground the SCS circuit with the HDS, then read the DTCs displayed in the multi-information display in the gauge control module, then go to B-CAN SYSTEM DIAGNOSIS TEST MODE A .

How to display DTCs on the MID of the gauge control module

Enter B-CAN System Diagnosis Test Mode 1 (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE 1 AND TEST MODE 2 (WITHOUT THE HDS) ). While in Test Mode 1, the DTCs which have been detected and stored individually by various B-CAN (Body-Controller Area Network) units will be shown one by one on the multi-information display when communication between the MICU and the gauge control module is normal. To scroll through the DTCs, press the SEL/RESET button.

Scheme 6

The unit that has stored the code can be identified by the number shown on the multi-information display.

How to clear DTCs

1. Enter B-CAN System Diagnosis Test Mode 1 (see «TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE 1 AND TEST MODE 2 (WITHOUT THE HDS)»(ref-513195-S21301063682012110700000) ).
2. While in Test Mode 1, press and hold down the SEL/RESET button for at least 10 seconds to clear the DTCs.

Body Controller Area Network (B-CAN) and Fast Controller Area Network (F-CAN)

The body controller area network (B-CAN) and the fast controller area network (F-CAN) share information between multiple electronic control units (ECUs). B-CAN communication moves at a slower speed (33.33 kbps) for convenience related items and for other functions. F-CAN information moves at a faster speed (500 kbps) for "real time" functions such as fuel and emissions data. To allow both systems to share information, the gauge control module translates and relays the information from B-CAN to F-CAN and from F-CAN to B-CAN. This is called the Gateway Function.

Scheme 7

Gateway Function

The gauge control module acts as a gateway to allow both systems to share information. The gauge control module translates and relays the information from B-CAN to F-CAN and from F-CAN to B-CAN.

Scheme 8

Network "Loss of Communication" Error Checking Function

The ECUs on the CAN circuit send messages to each other. If there are any communication malfunctions on the network, the multi-information display on the gauge control module can indicate the error messages by entering the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).

Scheme 9

Wake-up and Sleep Function

The multiplex integrated control system has wake-up and sleep functions to decrease parasitic draw on the battery when the ignition switch is in LOCK (0).

1. In the sleep mode, the multiplex integrated control system stops functioning (communication and CPU control) when it is not necessary for the system to operate.
2. As soon as any operation is requested (for example, a door is unlocked), the related control units in the sleep mode immediately wake up and begin to function.
3. When the ignition switch is turned to LOCK (0) with all the doors and the hatch closed, and the driver's door is opened, then closed, there is a delay of about 40 seconds before the control unit goes from the wake-up mode to the sleep mode.
4. The sleep mode will not function if any door or the hatch is open or if a key is in the ignition switch.

Note. Sleep and Wake-up Mode Test (see SLEEP AND WAKE-UP MODE TEST ).

Fail-safe Function

To prevent improper operation, the MICU has a fail-safe function. In the fail-safe mode, the output signal is fixed when any part of the system malfunctions (for example, a faulty control unit or communication line). Each control unit has a hardware fail-safe function that fixes the output signal when there is a CPU malfunction, and a software fail-safe function that ignores the signal from a malfunctioning control unit, which allows the system to continue operating normally.

When a CPU problem or an abnormal power supply voltage is detected, the MICU moves to the hardware fail-safe mode, and each system output load is set to the pre-programmed fail-safe value.

Software Fail-safe Control

When any of the data from the B-CAN circuit cannot be received within a specified time, or an unusual combination of data is recognized, the MICU moves to the software fail-safe mode. The data that was not received is forced to a pre-programmed value.

Power Supply Voltage Monitoring Function

The MICU monitors the power supply voltage (back-up voltage). If the voltage drops below 10 V, the MICU does not store DTCs.

Headlights

The MICU controls the headlights based on inputs from each switch.

Turn Signal/Hazard Warning Light

The MICU controls the turn signal/hazard warning lights based on inputs from the turn signal switch and the hazard warning switch.

The MICU controls the windshield and rear window washer motor based on inputs from each switch.

Collision Detection Signal (CDS)

The MICU controls the door lock actuators based on IG1 and SRS (CDS) inputs.

Power Door Locks*

The MICU controls the door lock actuators based on inputs from each switch.

This system can be customized in the multi-information display to suit the customer's needs. For more information about customizing options, refer to the Owner's Manual.

Keyless Entry System*

The MICU controls the door lock actuators based on the inputs signals from each switch.

This system can be customized in the multi-information display to suit the customer's needs. For more information about customizing options, refer to the Owner's Manual.

Key-in Reminder

Security Alarm System

The MICU controls the lighting system and horn based on inputs from each switch.

Keyless Answer Back (Without security)*

The MICU controls the lighting system and horn based on keyless signals sent by B-CAN.

This system can be customized in the multi-information display to suit the customer's needs. For more information about customizing options, refer to the Owner's Manual.

Security Answer Back (With security)*

The MICU controls the lighting system and horn based on keyless signals sent by B-CAN.

This system can be customized in the multi-information display to suit the customer's needs. For more information about customizing options, refer to the Owner's Manual.

Auto Door Lock*

The MICU controls the door lock actuators based on inputs from each switch.

This system can be customized in the multi-information display to suit the customer's needs. For more information about customizing options, refer to the Owner's Manual.

Auto Door Unlock*

The MICU controls of the door lock actuators based on inputs from each switch.

This system can be customized in the multi-information display to suit the customer's needs. For more information about customizing options, refer to the Owner's Manual.

Keyless Panic Function

The MICU controls the keyless PANIC operation based on signals sent by B-CAN.

HDS Inputs and Commands

Certain inputs happen so quickly that the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List. This should give the HDS time to update the signal on the Data List.

Because the HDS software is updated to support the release for newer vehicles it is not uncommon to see system function tests that are not supported.

Make sure that the most current HDS software is loaded.
