First you must find the codes. This is very easy. Just turn your car off. Start with the key in the off position. Turn the iginition key to the on and off positions (do not turn the key to the start position) within 5 seconds using this sequence: ON-OFF-ON-OFF-ON. Count the # of flashes between the pauses. For example for a code 12 you will get Flash Pause Flash Flash or for 55 you will get Flash Flash Flash Flash Flash Pause Flash Flash Flash Flash Flash.

Here are the codes for the 1984-1993 Chrysler Engine Control Unit.
Note these are for my car, which is a 1990 Lebaron 3.0L V6 as described in the Chilton's Repair Manual.
Code# Description
11
No Referance Signal During Cranking(No camshaft position sensor signal detected during engine cranking)
12
Power has been disconnected(will go away in 15 start stop cycles)
13
No change in MAP-Manifold Absolute Pressure from start to run(No differance recognized between the engine MAP reading and the barometric pressure reading at start-up)
14
MAP voltage to low or high(MAP sensor input below minimum or above maximum acceptable voltage)
15
No vehicle speed signal(No vehicle distance sensor signal detected during road load conditions)
16
Loss of Battery voltage While Running
17
Engine is cold too long(Engine coolant temp. remains below normal operating temp. during vehicle travel[bad thermostat])
21
O2 signal stays at center(Neither rich or lean condition detected from the oxygen sensor input) or O2 signal shorted to voltage(O2 sensor input voltage maintained above the normal operating range)
22
Coolant Sensor voltage to low or high(Coolant temp. sensor input above the maximum or below the minimum acceptable voltage)
24
Throttle Position Sensor-TPS voltage to high or low(Throttle position sensor input above the maximum or below the minimum acceptable voltage)
25
Idle air control motor circuits(an open or shorted cont=dition detected in one or more of the idle air control motor circuits)
26
Peak Injector Current not Reached
27
Injector Control Circut(Injector ouput driver does not respond properly to the control signal)
31
Evap purge solenoid circuit(An open or shorted condition detected in teh purge solenoid circuit)
32
EGR solenoid circuit(An open or shorted condition detected in the EGR transducer solenoid circuit) or EGR system failure(Requred change in air/fuel ratio not detected during diagnostic test)
33
Air conditioning clutch relay circuit(an open or shorted condition detected in teh A/C clutch relay circuit)
34
Speed control solenoid circuit(An open or shorted condition detected in teh speed control vacume or vent solenoid circuits)
35
Radiator Fan Relay circuits(An open or shorted condition detected in the radiator fan circuit)
36
Air switching solenoid is messed up
37
Torque convertor cluth solenoid CKT(An open or shorted condition detected in the torque convertor clutch solenoid circuit[Automatic Transmission only])
41
Generator field not switching properly(An open or shorted condition detected in the generator field control circuit)
42
Auto Shutdown Relay control Circuit(An open or shorted condition detected in the auto shutdown relay circuit)
43
Ignition Coil Is Messed up
44
Bad Connection or wiring from SMEC and the ignition key
46
Charging System voltage to high(Battery voltage sense input above target chargnig voltage during engine operation)
47
Charging System Voltage to low(Battery voltage snse input below target charging voltage during engine operatoin. Also no significand change detected in battery voltage during active test of alternator output)
51
Oxygen Sensor signal stays below center[lean](O2 Sensor signal input indicates lean air/fuel ratio condition during engine operation)
52
Oxygen Sensor Signal stays above center[rich](O2 sensor signal input indicates rich air/fuel ratio conditoin during engine operation)
53
Internal Controller Failure(Powertrain control moduel internal fault condition detected)
54
No sync pick-up signal(No fuel sync signal detected during engine rotation
62
Controller Failure EMR miles not stored(Unsucessful attemplt to write to an EEPROM location by the powertrain control module)
63
Controller Failure EEPROM write denied(Unsuccessful attempt to write to an EEPROM location by the powertrain control module.
55

I got my codes out of my Chilton's Chrysler Front Wheel Drive Cars 6-Cyl 1988-95 Repair Manual
