If the MIL stays on, connect the HDS to the data link connector (DLC) (A) located under the driver's side If the MIL (malfunction indicator lamp) has come onġ. Start the engine, and check the MIL (A).įig. HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)

With complex electronics (such as ECMs or PCMs) this can sometimes mean something works, but not the way it's supposed to. In simple electronics, this usually means something won't work at all. A short is an accidental connection of a wire to ground or to another wire. An open is a break in a wire or at a connection. 'Open' and 'short' are common electrical terms. If the MIL was on but then went out, the original problem may have been intermittent. If the malfunction indicator lamp (MIL) on the dash does not come on, check for poor connections or loose terminals at all connectors related to the circuit that you are troubleshooting. The term 'intermittent failure' means a system may have had a failure, but it checks OK now. If the symptom/indication goes away, replace the gauge control module.Ģ007-08 ACCESSORIES AND EQUIPMENT Gauges - Element NO - Substitute a known-good gauge control module. 29).Ĥ.
