1994 Eagle Summit Wagon AWD L4-1795cc 1.8L SOHCSECTION Troubleshooting Steps
FOREWORD
The most important point in troubleshooting is to determine "Probable Causes". Once the probable causes are determined, parts to be checked can be limited to those associated with such probable causes. Therefore, unnecessary checks can be eliminated. The determination of the probable causes must be based on a theory and be supported by facts and must not be based on intuition only.
TROUBLESHOOTING STEPS
If an attempt is made to solve a problem without going through correct steps for troubleshooting, the problem symptoms could become more complicated, resulting in failure to determine the causes correctly and making incorrect repairs. The four steps below should be followed in troubleshooting.
1. Observation of Problem Symptoms problems.
Observe the symptom carefully. Check if there are also other problems.
2. Determination of Probable Causes
In determining the probable causes. it is necessary to check the wiring diagram to understand the circuit as a system. Knowledge of switches. relays and other parts is necessary for accurate de termination. The causes of similar problems in the past must be taken into account.
3. Checking of Parts Associated with Probable Causes And Determining of Faulty Parts
Troubleshooting is carried out by making step by step checks until the true case is found. Always go through the procedures considering what check is to be made where for the best results.
4. Repair and Confirmation
After the problems are corrected. be sure to check that the system operates correctly. Also check that new problems have not been caused by the repair.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
