Remove the vapor line from the EVAP two way
valve, and connect it ro a T-fitting from a vacuum
gauge ano a vacuum pump as shown.

3. Apply vacuum slowly and continuously while watch-
ing the gauge. The vacuum should stabilize momen-
tarily at 0.8 - 2.1 kPa (6 - 16 mmHg, 0.2 - 0.6 in.Hg).
lf the vacuum stabilizes {valve opens) below
0.8 kPa (6 mmHg,0.2 in.Hg) or above 2.1 kPa(16'mmHg,0.6 in.Hg), install a new valve and retest.
4. Move the vacuum oumo hose from the vacuum fit-
ting to the pressure fining, and move the vacuum
gauge hose from the vacuum side to the pressure
side as shown.
PRESSUREstoE
Slowly pressurize the vapor line while watching thegauge. The pressure should be stabilize momentarily
above 1.0 kPa (8 mmHg, 0.3 in.Hg).
lf the pressure momentarily stabilizes (valve
opens) above'1.0 kPa (8 mmHg.0.3 in.Hg), the
valve is OK.
lf the pressure stabilizes below 1.0 kPa {8 mmHg,
0.3 in.Hg), install a new valve and retest.

Heater Unit
Replacement
SRS components are located in this area. Review the
SRS component locatio.s, precautions, and procedures
in the SRS section (23) before performing repairs or ser-
vtce.
1. When the engine is cool, drain the engine coolant
from the radiator (see section 1O).
@ oo not remove the radiator cap when
the engine is hot; the engine coolant is undol
prsssure and could sevdely scald you.
2. Ooen the clamD, then disconnect the heater valve
cable from the heater valve arm.

3. Disconnect the heater hoses lrom the heater unit.
CAUTION: Engine coolant will damaga paint. Ouick-
ly rinse any spilled engine coolant from painted
sudaces.
NOTE: Engine coolant will run out when the hoses
are disconnected, drain it into a clean drip pan.
4. Remove the mounting nut from the heater unit.
NOTE: When removing the mounting nut, take care
not to damage or bend the fuel pipes, brake pipes,
etc.

lgnition Control Module (lCM) Input Test
NOTE:
a See section 1 1 if the malfunction indicator lamp (MlLl
has been reported on.a Perform an input test for the ignition control module(lCM) after finishing the fundamental tests for the ig-nition system and the fuel and emissions systems.a The tachometer should operate normally.
1. Remove the distributo. ignition (Dl) cap, the rotor,and the leak cover.
2. Disconnect the BLK/YEL, WHT/BLU, YEL/GRN, andBLU wires from the lCM.
3. Turn the ignition switch ON {ll}. Check for voltage
between the BLK/YEL wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check the BLKiYEL
wire between the ignition switch and the lCM.a It there is battery voltage, go to step 4,

4. Turn the ignition switch ON (ll). Check for voltage
between the WHT/BLU wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check:- ignition coil.- WHT/BLU wire between the ignition coil and
tcM.
a lf there is battery voltage, go to step 5.
5. Disconnect the 32P connector from the ECM, and
check for continuity on the YEUGRN wire between
the ICM and ECM.
There should be continuity.
6. Check for continuity on the YEL/GRN wire to bodygrouno.
There should be no continuity.
7.Reconnect the ECM 32P connector.
Disconnect the gauge assembly 13P connector,
TCM 26P connector, and cruise control l4P connector.
9. Check for continuity on the BLU wire between the
ICM and tachometer.
There should be continuity.
'10. Check for continuity on the BLU wire to body ground.
There should be no continuity.
1 1 . lf all the tests are normal, reconnect the connectors,
and replace the lCM.
