Performance Test
Disconnect the wire from terminal N4.
Make a connection as described below using as
heavy a wire as possible (preferably equivalent to
the wire used for the vehicle).
Connect the battery as shown. lf the starter pinion
pops out. it is working properly. To avoid damaging
the starter, do not leave the battery connected for
more than 10 seconds.

Disconnect the battery from the M terminal. lf the
pinion does not retract, the hold-in coil is working
properly. To avoid damaging the starter, do not
leave the battery connected for more than 10 sec
onds.

pinion retracts immediately, it is working properly,
To avoid damaging the starter, do not leave the bat-
terv connected for more than 10 seconds.

7.
Clamp the starter firmly in a vise.
Connect the starter to the battery as described in
the diagram below, and confirm that the motor
starts and keeps rotating.
8, lf the electric current and motor soeed meet the
specifications when the battery voltage is at 11.5 V,
the starter is working properly.

lgnition System
lgnition Coil Test
Using an ohmmeter, measure resistance between the
terminals. lf the resistance is not within sDecifications,
replace the ignition coil.
NOTE: Resistance will vary with the coil temperature;
specifications are at 68"F (20'C).
Plimary Winding Resistance
{Between the A and B terminals):
0.6it - 0.77 0
Secondary Winding Resistance
{Between the A and secondary winding terminals):

lgnition Wire Inspection and Test
1.Carefully remove the ignition wires by pulling on
the rubber boots. Do not bend the wires; you might
break them inside.
Check the condition of the ignition wire terminals. lf
any terminal is corroded, clean it, and if it is broken
or distorted, replace the ignition wire.
IGNITION WIRE
Connect the ohmmeter probes and measure resis-
tance.
lgnition Wire Resistance:
25 kO max. at 68'F 120'Cl
IGNITION WIRE
4. lf the resistance exceeds 25 kO, replace the ignition
wire.

Description
Misfire detection is accomplished by monitoring the crankshaft speed with the crankshaft speed fluctuation (CKF) sensor
which is attached to the crankshaft.
lf misiiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence. and DTC
P0301, P0302, P0303 and/or P0304 will be stored. Then, after the misfire has ceased, the MIL will come on.
lf misfiring that increases emissions is detected during two consecutive driving cycles. the MIL will come on, and DTc
P0301, P0302, P0303 and/or P0304 will be stored.
NOTE: lJ some of the DTcs listed below are stored at the same time as a misfire DTc, troubleshoot those DTcs first, then
troubleshoot the misfire DTC.
