if you are going to do it youself it is wise to pick up a Haynes Repair Manual. they have a fairly good troubleshooting section. it is well worth the $20. dodge pickups 1974 thru 1993 2 & 4WD Full-size Pickups, Ramchargers, Traildusters. gasoline engines only.

I had to make this diagram for myself and figure some of you guys might need it, The haynes manual was worthless.

This is the wiring harness coming from the cab going to brake distributor, tranny, fuel sending unit, license plate lights, and tail lights. The the connection to the cab is the view if you were looking from the wires to the interface.

This tip is credited to crazzywolfie. If your mirrors are of the single post fold in design, and are loose, there is a screw at the bottom you can remove. Slide the chrome cover up and tighten the clamp for the post.

I wanted to post this as a sticky to help all the new owners of newer 1st gens.


1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition

CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles (normal)
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid CKT or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
45 Overdrive solenoid shorted or open (automatic transmission only)
46 Charging system voltage too high
47 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure
54 No Cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure

This site has a free manual for the A518 transmission. From what I see it should be very helpful for those that have problems.
