2006-08 ACCESSORIES & EQUIPMENT Multiplex Control System - Civic (Except Hybrid) COMPONENT LOCATION INDEX Fig. 1: Locating Multiplex Control System Components GENERAL TROUBLESHOOTING INFORMATION TROUBLESHOOTING CAN CIRCUIT RELATED PROBLEMS Using the HDS (Preferred method) 1. Go to B-CAN System Diagnosis Test Mode A to check for "Connected units" and DTCs (see TROUBLESHOOTING - B - CAN SYSTEM DIAGNOSIS TEST MODE A ). NOTE: Refer to the MULTIPLEX INTEGRATED CONTROL SYSTEM (GX) (SUPPLEMENT) article for additional information for the GX model. NOTE: Check the ECM/PCM for DTCs and troubleshoot ECM/PCM (see GENERAL TROUBLESHOOTING INFORMATION ) or F-CAN loss of communication errors first. 2006-08 ACCESSORIES & EQUIPMENT Multiplex Control System - Civic (Except Hybrid)

2. If no DTCs are retrieved, go to B - CAN SYSTEM DIAGNOSIS TEST MODE C (see ) or D (see TROUBLESHOOTING - B - CAN SYSTEM DIAGNOSIS TEST MODE D ). Without HDS (Use only if the HDS is unavailable) 1. Check for communication circuit problems using B-CAN System Diagnostic Test (see TROUBLESHOOTING - B - CAN SYSTEM DIAGNOSIS TEST MODE 1 AND TEST MODE 2 (WITHOUT THE HDS) ). 2. Check for DTCs. 3. Sort, and then troubleshoot the DTCs in the order below.  1 Battery voltage DTCs  2 Internal error DTCs  3 Loss of communication DTCs (beginning with the lowest number first; for example, if B1008 and B1011 are retrieved, troubleshoot B1008 first)  4 Signal error DTCs 4. If no DTCs are retrieved, use B-CAN System Diagnostic Test Mode 2 to check all inputs related to failure (see step 10TROUBLESHOOTING - B - CAN SYSTEM DIAGNOSIS TEST MODE 1 AND TEST MODE 2 (WITHOUT THE HDS) ). How to display DTCs on the gauge control module (tach) 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 odometer display when the communication between the MICU and the gauge control module is normal. To scroll through the DTCs, press the select/reset button. Fig. 2: Identifying Gauge Control Module (Tach) The unit that has stored the code can be identified by the number shown on the multi-information display. MICU REFERENCE MICU 10 Gauge control module 50 2006-08 ACCESSORIES & EQUIPMENT Multiplex Control System - Civic (Except Hybrid)

How to clear the DTC While in Test Mode 1, press and hold down the SELECT/RESET button for more than 10 seconds. Loss of Communication DTC cross-reference chart When an ECU is unable to communicate with the other ECUs on the CAN circuit, the other control units will set loss of communication DTCs. Use this chart to find the control unit that is not communicating. 1. Find the Transmitting Control Unit that is in the same row as all of the loss of communication DTCs retrieved. 2. Do the input test for the transmitting control unit.

SYSTEM DESCRIPTION MICU CONTROL FUNCTIONS INDEX The MICU (built into the under-dash fuse/relay box) is one of the B-CAN components. The MICU controls many systems related to the body controller area and a security system, and also works as a gateway to diagnose the other B-CAN connected ECUs with the HDS. Refer to each system circuit diagram for details. MICU CONTROL FUNCTIONS The MICU also controls the function of these circuits:  Entry lights control (map lights and ceiling light)  Exterior lights control (including the daytime running lights control)  Horn  Interlock system  Key-in reminder  Keyless entry  Lights-on reminder  Power door locks  Seat belt reminder  Security alarm  Turn signal/hazard flasher  Wiper/washer 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 System Function Multiplex Control Sends the switch input signal information to the MICU and outputs the information. The MICU controls the ECUs electric load and communication based upon the information received the B-CAN. On-Board Diagnosis The MICU has a gateway function which sends the results of the MICU internal diagnosis and the B-CAN connected ECUs diagnosis to the HDS. Self- Diagnosis Test mode 1 diagnoses the communication line between the MICU and B-CAN connected unit. Test mode 2 checks the switch inputs connected to the MICU. Interior Light (s) The MICU controls the interior lights ON, OFF and dimming based upon the information of the related switches and/or the B-CAN related information. Sleep Function The MICU has a sleep function, which it enters during the power down mode. 2006-08 ACCESSORIES & EQUIPMENT Multiplex Control System - Civic (Except Hybrid)

information, the gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN. Fig. 3: Body Controller Area Network (B - CAN) And Fast Controller Area Network (F - CAN)  The single wire method is used between the units not requiring the communication to move at a fast speed.  Using a single wire method reduces the number of the wires used on the body controller area network. GATEWAY FUNCTION The gauge control module (tach) acts as a gateway to allow both systems to share information, the gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN. Fig. 4: Identifying Gateway Function NETWORK "LOSS OF COMMUNICATION" ERROR CHECKING FUNCTION The ECUs on the CAN circuit send messages to each other. If there are any malfunctions on the network, the odo/trip display on the gauge control module can indicate the error messages by entering the gauge self- diagnostic function (see SELF - DIAGNOSTIC FUNCTION ). 2006-08 ACCESSORIES & EQUIPMENT Multiplex Control System - Civic (Except Hybrid)
