turn signal bulb SUZUKI GRAND VITARA 1987 Service Repair Manual

7) After it isconfirmed through steps 1) to 5) that oxygen sensor sends signals to ECM properly, check feed
back signal according to the following procedure. If feed back system operates properly, ECM should
send out feed back signal.
a) Connect an ohmmeter between terminal @I and body (ground). Be sure to connect positive (+) prod
of the ohmmeter to body (ground) and negative (-) prod to terminal @J as shown in below figure
and never connect the other way around.
NOTE:
For this check, cancel switch must be OFF (“CHECK ENGINE” light off).
b) If indicator of ohmmeter deflects when connected as described in the above step, it means that ECM
sends out feed back signal, that is, feed back system operates properly.
NOTE:
If indicator doesn’t deflect at all, reverse connection (positive prod to terminal @ and negative prod to
body) and check.
In this state, turning ON cancel or check switch causes “CHECK ENGINE” light to flash. If “CHECK
ENGINE” light does not flash, wire harness, bulb of light or cancel/check switch may be defective.
8) After checking, install ECM to instrument main panel, and make sure coupler is connected to ECM
securely.

INSPECTION
1) Trouble diagnosis
Symptom
1. Lights will not come on in either left or
right group of light.
2. Hazard light comes on but turn signal
lights will not.
3. No light comes on; or lights light up but
do not flicker.
4. Turn signal lights are satisfactory, but
hazard light will not come on.
5. Flickering freueqncy is erratic, or lights
remain lit.
6. Turning on hazard warning switch lights up
only one group of lights.
2) Turn signal switch
Using circuit tester, check for continuity
between each pair of terminals by referring to
the chart given below and figure at the right
for each position of turn signal switch lever.
Discontinuity means that contact points are
burnt or otherwise defective in the switch.
For example, switch is in sound condition if
continuity is noted between terminals 2 and
3, with lever in right-turn position, and
between terminals 1 and 3, with lever in left-
turn position.
Possible cause
Fusible link is blown off.
Open circuit (due to poor point contact) in turn
signal dimmer switch.
Defective relay unit.
Open circuit in hazard warning switch.
Light bulbs are defective or improperly grounded.
Defective contact in dimmer switch.

3) Hazard warning switch
Disconnect, lead wire of the hazard warning switch at its coupler. Set switch to ON position and check
for continuity with circuit tester between each of the following pairs of terminals; 2 and 3, 1 and 3, 5
and 6 among those shown in Fig. 21-10. The switch is in sound condition if continuity is noted between
each pair.
