Self diagnostics 2001 grand am - 2001 Pontiac Grand Am SE

Bernard,

HVAC failure
the car has 2 classes of HVAC< manual and ATC
the blower must blow on high.??? does it on high?
if not, check fuses, for blower. (if lower speeds only fail say so)
the blower is dead,
then say if dash controls are Manual or ATC<
atc = automatic temp,controls with a dash thermostat et cetra.

the diagnostic path is different.
the ATC has self test too. .with over 30 errors possible.

use comments to respond, not a new post. please.

working blind, no FSM sounds like it? factory service manual.
easter egg hunts,

climate control box.
the panel (control)

1. Disconnect and isolate the negative battery cable.
2. Remove the center bezel from the instrument panel and place it on a workbench.
3. Remove the screws that secure the electronic vehicle information center (EVIC) control and the A/C-heater control to the center bezel and remove the controls.

or
the automatic control zone module, option? AXC its called
The AXCM it it.

you scanned it and the DTC logs prove it bad.
FSM qoutes
The AZC control module is capable of three different
types of self-diagnostic tests, as follows:
² Fault Code Tests
² Input Circuit Tests
² Output Circuit/Actuator Tests
The information that follows describes:
² How to read the self-diagnostic display
² How to enter the AZC control module self-diagnostic
test mode
² How to select the self-diagnostic test types
² How to perform the different tests
and
To enter the AZC self-diagnostic mode, perform the
following:
(1) Depress the A/C and Recirc buttons at the
same time and hold. Rotate the left temperature control
knob clockwise (CW) one detent.
(2) If you continue to hold the A/C and Recirc buttons
depressed, the AZC control module will perform
a Segment Test of the vacuum fluorescent (VF) display.
In the Segment Test you should see all of the
display segments illuminate as long as both buttons
are held. If a display segment fails to illuminate, the
vacuum fluorescent display is faulty and the heater-
A/C control must be replaced.
(3) After viewing the Segment Test, release the
A/C and Recirc buttons and the display will clear
momentarily. If a 0 is displayed, then no faults
are set in the system.

find it,
unplug it
unscrew it
its out.


is it not inside this part?

the steps you want all steps
why not just read the book your self for 4bucks.

posted 100s of times.

its all there in the book and 4bucks aint squat.

Here is the definition.
You'll need a shop manual for the procedures.

P1494 JEEP Description The Evaporative emissions system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, can allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage.


During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LD pump to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

Hi James,

With the key in the ignition you cycle the key to the on position ( not start) 3 times and stop on the 4 th on position. it will appear in the odometer screen. It make take a few tries to get it. Cheers!

Check to ensure the front reservoir pump is connected and receiving power. Is the fuse bad?
It is possible the pump inlet is clogged. This would require removing the reservoir and flushing it.
If this is a washer with an external, self-priming pump, is the pump uptake tube in the cap missing?

check the fuses and blower motor resister first. Some systems don't have resisters. Use blower motor speed control instead.


SECTION 412-04: Control Components 2001 Crown Victoria/Grand Marquis Workshop Manual
REMOVAL AND INSTALLATION Blower Motor Speed Control Removal and Installation

1. Disconnect the wire harness connector.

1. Remove the screws and remove the blower motor speed control.

1. To install, reverse the removal procedure.

• The blower motor is inoperative—EATC

• Fuse.
• Circuitry open or shorted.
• A/C blower motor switch.
• A/C blower motor resistor.
• A/C blower motor.

• Go To Pinpoint Test

Electronic Automatic Temperature Control Module Self-Test

• The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A diagnostic tool must be used to retrieve these concerns.
• The EATC module self-test will detect concerns in the system control functions and will display hard diagnostic trouble codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 4° and 32°C (40° and 90°F) when carrying out the self-test. If the temperatures are not within the specified ranges, false in-car temperature sensor DTCs will be displayed.
• The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated.
• To enter the self-test, press the OFF and FLOOR buttons simultaneously and then press the AUTOMATIC button within two seconds. The display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed.
• If any DTCs appear during the self-test, follow the diagnostics procedure given under ACTION for each DTC given.
• If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Improper Operation.
• To exit self-test and retain all intermittent DTCs, push the blue (cooler) button. The control will exit self-test, retain all intermittent diagnostic trouble codes and then turn OFF (display blank).
• To exit the self-test and clear all DTCs, press the DEFROST button. The vacuum fluorescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared.
• Always exit the self-test before powering the system down (system turned OFF).
• Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.

have you changed fuel filter ?

Generally check engine light problems have to be checked with a diagnostic tool. Under the dash would be a rectangular shaped plug with about 8 prongs, not sure exactly. That's normally where you would plug in the diagnostic tool.

Technical Point: "Fire" aka high voltage, should be coming FROM the coil not TO it. If your coil is not being energized the first check after looking for obvious loose connections is testing voltages to the components IAW the shop manual. If all are go remove the coil and take it in for a test to see if it is producing sufficient spark energy. Alternatively swap coil with a known working coil to isolate the problem. Also initiate a self test of the built-in diagnostics and check for ignition related codes.( see the shop manual)
