Cruise Control Input Test
NOTE: Always make sure that you have the latest Honda Diagnostic System (HDS) software before doing the input
tests.
1. Connect the HDS to the data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain control module (PCM). If it does not communicate, troubleshoot the DLC circuit (see page 11- 204).
4. Go to PGM-FI, and check for DTCs (see page 11-3).
5. Do the following tests while monitoring parameters in the PGM-FI DATA LIST with the HDS. NOTE: Intermittent failures are often caused by loose circuit connections. While monitoring cruise control inputs,
flex the circuit wires, and note if any of the test results change.

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).

The knock control system adjusts the ignition timing to
minimize knock.
The MAP sensor converts manifold absolute pressure
into electrical signals to the ECM/PCM.
The vehicle has certain readiness codes that are part of
the on-board diagnostics for the emissions systems. If
the vehicle’s battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these codes are reset. In some states,
part of the emissions testing is to make sure these
codes are set to complete. If all of them are not set to
complete, the vehicle may fail the test, or the test
cannot be finished.
To check if the readiness codes are set to complete,
turn the ignition switch to ON (II), but do not start the
engine. The MIL will come on for 15 20 seconds. If it
then goes off, the readiness codes are complete. If it
flashes five times, one or more readiness codes are not
complete. To set each code, drive the vehicle or run the
engine as described in the procedures (see page 11-69). The mass air flow (MAF) sensor/intake air temperature
(IAT) sensor contains a hot wire sensor, a cold wire
sensor, and a thermistor. It is located in the intake air
passage. The resistance of the hot wire sensor, the cold
wire sensor, and the thermistor change due to intake air
temperature and air flow. The control circuit in the MAF
sensor controls the current to keep the hot wire at a set
temperature. The current is converted to voltage in the
control circuit, then output to the ECM/PCM.
This sensor detects countershaft speed.

THROTTLE VALVE
THROTTLE POSITION
(TP) SENSOR and
THROTTLE ACTUATOR
The throttle body is a single-barrel side draft type. The
lower portion of the throttle valve is heated by engine
coolant from the cylinder head to prevent icing of the
throttle plate. When the engine is cold, the A/C compressor is on, the
transmission is in gear, the brake pedal is pressed, the
power steering load is high, or the alternator is
charging, the ECM/PCM sends signal to the throttle
position to maintain the correct idle speed.
The brake pedal position switch signals the ECM/PCM
when the brake pedal is pressed.
The EPS signals the ECM/PCM when the power steering
load is high.
During deceleration with the throttle valve closed,
current to the injectors is cut off to improve fuel
economy at engine speeds over 1,000 rpm. Fuel cutoff
control also occurs when the engine speed exceeds
6,900 rpm (K20Z3: 8,200 rpm), regardless of the
position of the throttle valve, to protect the engine from
over-revving. When the vehicle is st
opped, the ECM/
PCM cuts the fuel at engine speeds over 5,000 rpm
(K20Z3: 7,700 rpm). On a cold engine, fuel cut occurs at
a lower engine speed.
When the ignition switch is turned to ON (II), the ECM/
PCM grounds PGM-FI main relay 2 (FUEL PUMP) which
feeds current to the fuel pump for 2 seconds to
pressurize the fuel system. With the engine running, the
ECM/PCM grounds PGM-FI main relay 2 (FUEL PUMP)
and feeds current to the fuel pump. When the engine is
not running and the ignition is turned to ON (II), the
ECM/PCM cuts ground to PGM-FI main relay 2 (FUEL
PUMP) which cuts current to the fuel pump.
PGM-FI main relay 1 is energized whenever the ignition
switch is ON (II), to supply battery voltage to the ECM/
PCM, power to the injectors, and power for PGM-FI
main relay 2 (FUEL PUMP). PGM-FI main relay 2 (FUEL
PUMP) is energized to supply power to the fuel pump
for 2 seconds when the ignition switch is turned to
ON (II), and when the engine is cranking or running.
