Index Honda POWERSPORTS HDS USER GUIDE 0 Honda POWERSPORTS HDS USER GUIDE INTRODUCTION Nearly all Honda PGM-FI equipped powersports models have varying levels of self-diagnostic abilities. Early PGM-FI models (1998-2002) were only equipped with the Malfunction Indicator Light (MIL) to signal the rider and technician of problems with the fuel/ignition system. The MIL flashes in certain patterns to indicate the problem component(s). Mod- els with this early self diagnostic system require the use of a pin-out box, digital multi-meter, and the Honda Service Manual for diagnostic troubleshooting. But a more sophisticated tool for retrieving fail codes and diagnosing PGM-FI systems was needed, so the Honda Diagnostic System (HDS) was developed. Most PGM-FI equipped models built since 2003 are HDS compatible, allowing for the retrieval of trouble codes without having to read the MIL blink pattern. Although the Service Manual is still required, HDS now allows the user to monitor ECM sensor input signals (voltage values) directly, without a pin-out box. Some models feature an integrated Engine Control Module (ECM) and Powertrain Control Module (PCM) that controls the function of the PGM-FI, ignition, and electric shift/automatic transmission. Models that feature Electric Power Steering (EPS) or an airbag have standalone Electronic Control Units (ECU) that can only be accessed with the HDS pocket tester. For Honda powersports and marine products the HDS is a hand-held PC based system where the pocket-PC has been specifically customized for interfacing Honda HDS compatible ECM/PCMs. HONDA DIAGNOSTIC SYSTEM (HDS) CAPABILITIES: RETRIEVE DIAGNOSTIC TROUBLE CODES (DTC) DTC’s are the equivalent of the blinking Malfunction Indicator Light (MIL, or check-engine light). When the MIL flashes nine times, it guides you to a general fault area (IAT sensor). Scanning the ECM with HDS will give you more specific results, like IAT sensor voltage too low (DTC 9-1) or IAT sensor voltage too high (DTC 9-2). VIEW ACTUAL OPERATING CONDITIONS Beyond just reading trouble codes, the HDS can read the actual voltage values of the signals sent from various sensors to the ECM; like how long the fuel injectors are open. This data can help with the diagnosis of driveability problems that do not set a DTC (check engine light). OPERATIONAL COMPONENT TESTS On some models you can override the ECM and operate engine components (like the Dual Clutch Transmission (DCT) shift control motor) to test their operation and function. STORE ENGINE PERFORMANCE RECORDS HDS allows for saving and filing engine performance data to create permanent performance records of vehicles. You can also easily e-mail performance data to Honda TechLine for help with analyzing unusual problems. NOT A MAGIC WAND Knowing the controls on a lathe doesn’t mean you’re a machinist, and knowing your way around the menus of the HDS won’t let you magically fix faulty engines. It is important that you understand how PGM-FI and electric-shift/auto- matic transmissions work in order successfully diagnose problems with HDS. Consult the Technical Features section of the model specific Service Manual for detailed information on how these systems operate. If, however, you know why high voltage at a temperature sensor could be an open circuit, or if you ever wished you could measure voltage variations as the throttle position sensor moves, the HDS can be valuable. Engines, regardless of all the electronic components, still need a fairly precise mixture of fuel and air in the combus- tion chamber to be ignited by an accurately timed spark. Using HDS and the Genuine Honda Service Manual you will be able to efficiently diagnose PGM-FI, powertrain, and EPS problems on late-model Honda powersports products. Honda POWERSPORTS HDS USER GUIDE 1 SETTING UP THE HDS BEFORE YOU OPEN THE BOX Find the label. Be sure the part number is 3557-0115-01 and record the serial number for future reference. CONTENTS OF THE CASE When you open the HDS kit you’ll find: HDS pocket tester 64MB SD card (in the tester) AC charger with tethered adapter Active Sync cable: Connects HDS to PC, either through serial or USB ports. 1.5 m 4-pin DLC cable: Connects HDS to Honda vehicle through DLC. Also charges HDS from the vehicle. Installation software CD-ROM, spare case membranes, stylus, and four reusable cable ties Additional documents. Typically these are not needed, however should be retained for future reference. User self-test adaptor User self-test power adapter Remote trigger cable: Triggers SnapShots while riding. Honda POWERSPORTS HDS USER GUIDE 2 HDS ARCHITECTURE A FEW ACRONYMS – Honda Diagnostic System (HDS): All of the software and hard- ware that allows you to communicate with the ECM on Honda PGM-FI equipped vehicles. – Engine Control Module (ECM): Controls the engine operation with the engine operating information it receives. It also analyzes system operation. – Powertrain Control Module (PCM): On vehicles equipped with PGM-FI and an electric shift or automatic transmission; controls engine and transmission operation. It also analyzes systems operation. – Honda Interface Module (HIM): Allows the software of the ECM or PCM to communicate with the HDS software. It is powered only when the HDS is connected to a vehicle with its ignition switch ON. Its firmware is updated from the HDS as necessary. – iPAQ: The HP/Compaq Personal Digital Assistant that is the hardware platform for the pocket tester. It’s inside the red protec- tive housing. – Data Link Connector (DLC): A term applied to the socket on the vehicle (was formerly called the SCS connector) that allows HDS communication with the ECM or PCM. CONNECTIONS AND PORTS On top, you’ll find the sockets for the Active Synch cable and the AC charger. Notice that the sockets allow plugs to be inserted in only one way. The black object with the sockets is the Honda Interface Module (HIM). Under the black dome is the socket for the SD memory card and a spare stylus. One push releases them, and another push secures them. Honda POWERSPORTS HDS USER GUIDE 3 MEMORY CARD This is the non-volatile memory of the pocket tester; it doesn’t go away if the tester’s battery is dead. It stores a copy of the HDS soft- ware that you can quickly install, and it stores all of your saved files. Sometimes the tester cannot find the memory card. If this happens when you’re installing the software from your PC, a warning mes- sage comes up and won’t let you proceed. To make the card reap- pear, just push it in to remove it, clean the contacts with Deoxit® or rubbing alcohol, and then reinstall it. The tester should then see it again. Do this anytime the tester reports it cannot find the card. The tester will notify you if it does not sense the card, and will not pro- ceed with storage operations. SOFT RESET On the bottom, under a protective plug, is the reset button; like hit- ting ctrl-alt-del on a computer. You can’t see it, but if you stick the tip of the stylus* in there, you’ll feel it. When you push, it will give you a red and white screen and a loud beep as the HDS restarts. The size and shape of the stylus tip is critical when doing a reset, other brands of stylus may not fit the reset button. HARD RESET Another reset technique is like formatting the hard drive of a PC, it removes everything in the pocket tester and restores it to its out-of- the-box condition. Because the consequences of this reset are dras- tic, it takes some contortion on your part. The HDS must be disconnected from the AC-charger to complete a hard reset. You must press the two outer buttons on the iPAQ and hold them while holding the stylus on the reset button; maintaining pressure until the screen goes black. At this point it’s dead, and the only way to revive it is to connect it to a power source. COVERS On the front is the flip-up screen. This protective device often inter- feres with HDS operation and is easily removed. There is also a membrane that covers the face that may make drag- ging the stylus a little sticky, but it does a good job keeping dirt and water out of the unit. Use it only when testing a PWC on water. Replace it with a provided spare if it gets damaged.
