The stop lamp switch is normally opened. When the ignition switch ON and brake ON, the battery voltage is supplied to
the ECM. A scan tool should display ON when brake pedal is depressed and should read OFF with brake pedal rele-
ased.

ENGINE CONTROL MODULE
YAA1F830
The Engine Control Module (ECM), located inside the right side kick panel, is the control center of the fuel injection
system. It constantly looks at the information from various sensors and controls the systems that affect the vehicle’s
performance. Engine rpm and air mass are used to measure the air intake quantity resulting in fuel injection metering.
The ECM also performs the diagnostic functions of the system. It can recognize operational problems, store failure
code(s) which identify the problem areas to aid the technician in making repairs.
There are no serviceable parts in the ECM. The calibrations are stored in the ECM in the Programmable Read Only
Memory (PROM).
The ECM supplies either 5 or 12 volts to power the sensors or switches. This is done through resistance in the ECM
which are so high in value that a test light will not come ON when connected to the circuit. In some cases, even an
ordinary shop voltmeter will not give and accurate reading because its resistance is too low. You must use a digital
voltmeter with a 10 Mohm input impedance to get accurate voltage readings. The ECM controls output circuits such as
the ignition coils, the fuel injectors, the fuel pump relay, the intake manifold resonance flap, the camshaft actuator, the
canister purge valve, etc., by controlling the ground circuit.

CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless other -
wise noted.

Circuit Description
The 58X reference signal is produced by the CKP sensor. During one crankshaft revolution, 58 crankshaft pulseswill
be produced. The ECM uses the 58X reference signal to calculate engine rpm and CKP. The ECM constantly monitors
the number of pulses on the 58X reference circuit and compares them to the number of Camshaft Position (CMP)
signal pulses being received. If the ECM receives and incorrect number of pulses on the 58X reference circuit, this
failure code will set.

Circuit Description
The KS system is used to detect engine detonation, allowing the ECM to retard the ignition control spark timing based
on the KS signal being received. The KS signal’s amplitude and frequency depend upon the amount of knock being
experienced. The ECM monitors the KS signal and can diagnose the KS sensor and circuitry.

2. Measure the resistance between the coupling terminal pin No. 118 and No. 117 using a multimeter.
Specified Value

Notice:Replace the KS if the measured values is out of the specified values. Check the connector and wire connec-
tion between ECM and the KS if the measured values are normal.
