Corporation could not possibly know, evaluate, and advise the service trade of all conceivable ways that service may be performed, or of the possible hazards of each. Consequently, Chrysler Corporation has not undertaken any such broad service review. Accordingly, anyone who uses a service procedure, or tool, that is not recommended in this publication must assure oneself thoroughly that neither personal safety, nor vehicle safety, be jeopardized by the service methods they select.

Page 27 HARNESS CONNECTOR INSPECTION CONNECTOR CONTINUITY AND VOLTAGE TEST When checking continuity and/or voltage at the waterproof connectors, follow the steps below to avoid poor connector contact and/or reduced waterproof performance of connectors. (1) When checking is performed with the circuit in the state of continuity, be sure to use the special tool (harness connector).
Page 28 HARNESS CONNECTOR INSPECTION (2) Insert harness of terminal to be rectified deep into connector from harness side and hold it there. (3) Insert tip of screwdriver [I.4 mm (.06 in.) width] into connector in a manner as shown in the figure, raise housing lance slightly with it and pull out harness.
Page 29 HARNESS CONNECTOR INSPECTION RECTANGULAR WATERPROOF CONNECTOR (2) Insert tip of screwdriver [*0.8 mm (.03 in.) width] into connector in a manner as shown in the figure, push it lightly to raise housing lance and pull out harness. conventional driver to suit the size. (3) Press contact point of male terminal down by holding a screwdriver [I .4 mm (.06 in.) width] in a manner as shown in the figure.
Page 30 HOW TO DIAGNOSE 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.
Page 31 HOW TO DIAGNOSE INSPECTION Check relay operation, blower motor rotation, light illumina- tion, etc. visually or aurally. The flow of current is invisible but can be checked by the operation of the parts. 2. Simple checks For example, if a headlight does not come on and a faulty fuse or poor grounding is suspected, replace the fuse with a new one or ground the light to the body by a jumper wire to determine which part is responsible for the problem.
Page 32 HOW TO DIAGNOSE 3. Jumper wire A jumper wire is used to close an open circuit. Never use one to connect a power supply directly to a load. 1600227 4. Voltmeter A voltmeter is used to measure the circuit voltage. Normally, the positive (red lead) probe is applied to the point of voltage measurement and the negative (black lead) probe to the body ground.
Page 33 HOW TO DIAGNOSE 2. SWITCH CONNECTION This figure illustrates a complex switch. The continuity between terminals at each position is as indicated in the table below. 1 st stage 3’ O-O denotes continuity between terminals. CHECKING RELAYS Cover Coil . Spring magnetized to attract the iron piece, closing (ON) the contact at the tip of the iron piece.
Page 34 HOW TO DIAGNOSE When a normal close type relay as illustrated here is Normal close (NC) type checked, there should be continuity between terminals (1) Deenergized state Energized state and (2) and between terminals 3 and 4 when the relay is deenergized, and the continuity should be lost between terminals 3 and 4 when the battery voltage is applied to the terminals 1 and 2.
Page 35 HOW TO DIAGNOSE CHECKING CABLES AND WIRES 1. Check connections for looseness, rust and stains. 2. Check terminals and wires for corrosion by battery electro- lyte, etc. 3. Check terminals and wires for open circuit or impending open circuit. 4. Check wire insulation and coating for damage, cracks and degrading.
Page 36 HOW TO DIAGNOSE GENERAL ELECTRICAL SYSTEM CHECKS A circuit consists of the power supply, switch, relay, load, ground, etc. There are various methods to check a circuit including an overall check, voltage check, shortcircuit check and continuity check. Each of these methods is briefly described in the following.
Page 37 HOW TO DIAGNOSE 2. SHORT CIRCUIT CHECK A blown fuse indicates that a circuit is shorted. The circuit responsible can be determined by the following proce- dures. connector @...
Page 38 HOW TO DIAGNOSE 3. CONTINUITY CHECK test light should come on or the ohmmeter should read 0 ohm only when the terminals 1 and 2 are intercon- nected. (2) When the switch is in the ON position, the self power test light should come on or the ohmmeter should read 0 ohm only when the terminals 3 and 4 are intercon- nected.

Page 423 CHASSIS ELECTRICAL - Theft-alarm System CHECKING THE CIRCUIT AND INDIVIDUAL PART 1. ETACS POWER-SUPPLY AND GROUND CIRCUITS Description of operation The battery supplies a stabilized 5V power supply to the ECU, via the constant-voltage circuit and terminal 51 (which is directly connected to the battery).
Page 424 CHASSIS ELECTRICAL - Theft-alarm Svstem 3. HOOD SWITCH INPUT CIRCUIT Description of operation When the hood is closed (the hood switch is switched OFF), HIGH-level signals are sent to the ECU: When the hood is opened (the hood switch is switched ON), LOW-level signals are sent to the ECU.
Page 425 CHASSIS ELECTRICAL 5. DOOR LOCK ACTUATOR SWITCH INPUT CIRCUIT Description of operation When a door is locked by the lock knob or the key, the door lock actuator switch is switched OFF, and HIGH-level signals are sent to the ECU. These signals activate the timer circuit of the ECU, thereby causing the activation circuit to function, thus activating the door lock actuator of all doors.
