System Description
The functions of the fuel and emission control systems are managed by the engine control module (ECM) on vehicles
with manual transmissions or the powertrain control module (PCM) on vehicles with automatic transmissions.
The ECM/PCM detects a failure of a signal from a sensor or another control unit and stores a Temporary DTC or a DTC.
Depending on the failure, a DTC is stored in either the first or the second drive cycle (K20Z3 engine: DTC P0457, turns
on the malfunction indicator lamp (MIL) during the third drive cycle). When a DTC is stored, the ECM/PCM turns on the
malfunction indicator lamp (MIL) by a signal sent to the gauge via F-CAN.  When an abnormality occurs in the signal from a sensor or from another control unit, the ECM/PCM stores a DTC
and turns on the MIL immediately.
 When an abnormality occurs in the signal from a sensor or from another control unit in the first drive cycle, the
ECM/PCM stores a Temporary DTC. If the failure continues in the second drive cycle, the ECM/PCM stores a DTC and
turns on the MIL.
When an abnormality occurs in the signal from a sensor or another control unit, the ECM/PCM ignores the signal and
substitutes a pre-programmed value that allows the engine to continue running. This causes a DTC to be stored and
the MIL to come on.
When the ignition switch is turned to ON (II), the ECM/PCM turns on the MIL via the F-CAN circuit for about 15 to
20 seconds to check the bulb condition. If any readiness codes are not set to complete, the MIL flashes five times. If all
readiness codes are set to complete, the MIL goes off.
After the ignition switch is turned to LOCK (0), the ECM/PCM stays on (about 30 minutes). If the ECM/PCM connector is
disconnected during this time, the ECM/PCM may be damaged. To cancel this mode, disconnect the negative cable
from the battery or jump the SCS line with the HDS after the ignition switch is turned to LOCK (0).

NOTE:
 Check the connectors for poor connections or loose terminals.
 Before troubleshooting, get the navigation system anti-theft code, then write down the audio presets.
 After troubleshooting, re-enter the anti-theft code, and re-initialize the navigation system, then enter the
audio presets.
 Check for aftermarket accessories that use the same power circuit. A feedback can cause this problem.
1. Remove the key from the ignition.
Go to step 2.
The system is OK at this time.
2. The vehicle may have been used as a demonstration vehicle at an event like an auto
show. In these events, power is often jumpered to
the navigation system so that the ignition key is not
needed in the vehicle. At the end of the show, the
jumper wire may not have been removed. Check
the navigation unit connector A (17P) for a non-
factory jumper wire in series with the factory cable.
Remove the jumper wire, and re-test. Return
the jumper wire to Tech Line.
Go to step 3.
3. Check if the audio unit works.
Troubleshoot the ACC circuit for a short to
power with another circuit.
Replace the navigation unit (see page 23-155). NOTE:
 Check the vehicle battery condition first.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode and use
Version (see page 23-149).
 Check for connectors for poor connections or loose terminals.
 Before troubleshooting, make sure you have anti- theft codes for the navigation system.
 After troubleshooting, enter the anti-theft codes for the navigation system.
 Make sure that the correct navigation DVD color and version are installed.
 Inspect the navigation DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
1. Make sure the anti-theft code for the navigation system is entered.
2. Go into the Diagnostic Menu and use the Navi System Link test (see page 23-136).
