Using Check Engine
Malfunction Indicator Lamp
If suitable diagnostic read-out tool is not available, stored diagnostic
trouble codes (DTC's) can be accessed directly through the power loss/check
engine lamp. To call up DTC's, cycle ignition switch On, Off, On, Off and On
within five seconds. Once the lamp starts flashing the stored diagnostic
trouble codes (DTC's), it cannot be stopped. If a DTC is missed, the entire
procedure must be repeated. The lamp will not indicate if oxygen feedback
system is switching lean-rich or if idle motor system is operational.

Using C-4805 Tester
To obtain diagnostic trouble codes using diagnostic read-out tool No.
C-4805, connect the unit to the diagnostic connector located in the engine
compartment near the strut tower. Place the Read/Hold switch on the readout
box in Read position. Start the engine if possible, then cycle the
transmission selector and air conditioning switch and shutoff the engine.
Cycle the ignition switch on and off twice, then turn ignition on and record
all DTC's displayed within five seconds. Note that the power loss/check
engine lamp should light for two seconds as a bulb check.
Using Diagnostic Readout Box II (DRB
II)
1987-1988 Models
The Diagnostic Readout Box II (DRB II) must be used to enter the system
into one of five test modes: A Diagnostic Test Mode, Circuit Actuation Test
Mode (ATM), Switch Test Mode, Sensor Test Mode and Engine Running Test Mode.
These five test modes are required to diagnose the system as called for in
Diagnostic Procedures. To use the tester, proceed as follows:
- Connect the diagnostic readout box Serial Communication Interface
(SCI) to the engine controller connector located near engine controller,
and then connect the red power supply lead to the positive battery
terminal.
- Plug the desired cartridge into the readout box. For a few seconds a
test pattern, then an identification logo will appear on the display.
After a few more seconds the display will read Select Model Year.
- Press the F1 or F2 key until the display indicates 1988, then press
the Yes key. The display will now read Select System. If at this time
you wish to return to Select Model Year, press the No key.
- Press the F1 or F2 key until the display indicates Power Train, then
press the yes key. The display will now read Select Engine. If at this
time you wish to return to Select System, press the No key.
- Press the F1 or F2 key until the display indicates EFI/Turbo, then
press the Yes key. The display will now read Select Test. If at this
time you wish to return to Select Engine, press the No key.
- At this point, one of two tests must be selected: Engine Off Test or
Engine Running Test. If the Diagnostic Test Mode, switch Test Mode,
circuit Actuation Test Mode (ATM Test) or Sensor Test Mode is required,
select the Engine Off Test. If the Engine Running Test Mode is required,
select the Engine Running Test. Press the F1 or F2 key until the desired
test is displayed on the readout, press the Yes key, then proceed to the
desired test mode as outlined under Test Modes. If at this time you wish
to return to Select Test, press the No key.

- Connect DRB II tester to diagnostic connector, using suitable adapter.
On 2.2L and 2.5L models with TBI, the diagnostic connector is located in
the engine compartment near the engine controller. On 2.2L, 2.5L, 3.0L,
3.3L and 3.8L MFI engines except Concorde, Intrepid, Trucks, Vans,
Vision & 1994-95 New Yorker LHS models, the diagnostic connector is
located in the engine compartment near the strut tower. On Concorde,
Intrepid, Vision & 1994-95 New Yorker, and LHS models, the data link
connector (DLC) is located in the passenger compartment, under the
center of the instrument panel toward the driver’s side. On 1989-95
Mini-Vans, the DLC is located in the engine compartment on the left hand
inner front fender well. On 1989-1992 Full-Size Vans, the DLC is located
in the engine compartment on the cowl near the Single Module Engine
Controller. On 1993-95 Full Size Vans, the data link connector is
located in the engine compartment on the cowl near the brake booster. On
1989-95 Dakota models, the DLC is located in the engine compartment on
the right-hand inner front fender well near cowl. On Full-Size Pickup
& Ram charger models, the data link connector is located in the
engine compartment on the left- hand inner front fender well near cowl.
On all 1996 passenger car and light truck models, the DLC is located
below the instrument panel near the steering column.
- If possible start engine and cycle A/C compressor On and Off, then
place ignition switch in the Off position.
- Place ignition switch in the On position, access Read Fault Screen and
note all diagnostic trouble codes displayed on the DRB II screen.
