(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs, etc.
(9) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the
DTCs and freeze frame data, etc.
HINT:
Take care not to turn the ignition switch OFF, as turning it off
switches the diagnosis system from Check mode to Normal
mode, which all DTCs etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
(1) When using the hand±held tester:
The following operation will erase the DTC and
freeze frame data. Operate the hand±held tester to
erase the codes.
(2) When not using the hand±held tester:
Remove the EFI fuse from engine room J/B for 60
seconds or more.
4. DATA LIST
HINT:
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
of the methods to shorten the work time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) According to the display on tester, read the ºDATA LISTº.

HINT:
Performing the ACTIVE TEST using the hand±held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one of the
method to shorten the work time.
It is possible to display the DATA LIST during the ACTIVE TEST.

of the trouble. If the problem is that the transaxle does not shift up, shift down, or the shift point is too
high or too low, conduct the following road test referring to the automatic shift schedule and simulate
the problem symptoms.

DTC P0010 CAMSHAFT POSITION ”A” ACTUATOR
CIRCUIT (BANK1)
HINT:
This is the troubleshooting procedure of the oil control valve (OCV).
CIRCUIT DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, the Oil Control Valve (OCV) and the VVT control-
ler. The ECM sends a target ”duty−cycle” control signal to the OCV. This control signal, applied to the OCV,
regulates the oil pressure supplied to the VVT controller. Camshaft timing control is performed based on en-
gine operation conditions such as intake air volume, throttle position and engine coolant temperature.
The ECM controls the OCV based on the signals output from several sensors. The VVT controller regulates
the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the
camshaft and the crankshaft is optimized, and the engine torque improves, fuel economy improves, and ex-
haust emissions decrease. The ECM detects the actual valve timing using signals from the camshaft position
sensor and the crankshaft position sensor. The ECM performs feedback control and verifies target valve
timing.

DTC P2118 THROTTLE ACTUATOR CONTROL MOTOR
CURRENT RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is
monitored and when the voltage is low (less than 4V), the ECM concludes that the ETCS has a fault and
current to the throttle control motor is cut.
When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage
is low, the current to the motor is cut. If repairs are made and the system has returned to normal, turn the
ignition switch to OFF. The ECM then allows current to flow to the motor and the motor can be restarted.
HINT:
This Electrical Throttle Control System (ETCS) does not use a throttle cable.
