DIAGNOSIS & TESTING

Note. The following trouble shooting charts and illustrations are Courtesy of Chrysler Motors.

DIAGNOSTIC TEST PROCEDURE

Diagnostic test procedures are designed to detect system faults as quickly as possible. Body fault codes are accessed through Chrysler Collision Detection (CCD) bus diagnostic connector. On Dynasty and New Yorker, CCD bus diagnostic connector is located under middle of dashboard. On Fifth Avenue and Imperial, CCD bus diagnostic connector is located under left side of dash. (Scheme 9) Chrysler's Diagnostic Readout Box II (DRB-II) tester is used to access information from CCD bus diagnostic connector.

Scheme 9

DRB-II tester, jumper wires, analog volt/ohmmeter and circuit tester will be needed for testing. Proceed to TEST 1: IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS in this article. When system problem is identified according to customer's complaint, perform diagnostic test indicated in flow chart. Information for using the DRB-II during testing is given in diagnostic charts. Once problem has been determined, perform test procedures using these guidelines

1. Always start at the first test in each category or incorrect results may occur.
2. Only perform test steps indicated. It is NOT necessary to perform all steps in a test.
3. At the end of each test step, reconnect all wires and install any components removed for testing.
4. Vehicle battery must be fully charged.
5. Use extreme care when connecting or disconnecting wiring during testing to prevent accidental grounding or shorting.
6. DO NOT use a test light in place of a voltmeter. Damage to electronic components may occur.

CCD BUS TESTING

Using DRB-II tester, a bus problem will show up in one of 3 ways. Despite passing automatic bus test, a NO RESPONSE message may be displayed rather than an expected value on the DRB-II. It is impossible to use DRB-II until reason for NO RESPONSE message is found and corrected. A NO RESPONSE message can be caused by

1. A bus wire open or poorly connected at a module.
2. Ground or power supply is missing at certain modules.
3. Ignition is turned off and body controller has timed out.

A major bus failure can cause anything from an ENGINE NO START CONDITION to a blank message screen on Electronic Vehicle Information Center (EVIC) head. The automatic bus test will not complete or allow access to further system tests at this point and Red light on DRB-II will come on. A major bus failure can be caused by

1. Short To Ground
2. Short To Battery Voltage
3. Short To 5 Volts
4. Bus "+" & Bus "-" Shorted Together

Critical bus messages preventing bus from operating properly are

1. NO TERMINATION
2. BIAS LEVEL TOO HIGH
3. BIAS LEVEL TOO LOW
4. NO BUS BIAS
5. BUS - OPEN
6. BUS + OPEN
7. BUS + & BUS - OPEN
8. NOT RECEIVING BUS MESSAGES CORRECTLY

DRB-II will display any of these messages on display screen and then go to the next level of testing with no Red light. The only interference will come when trying to access a module directly related to or causing bus failure. A NO RESPONSE message will then appear.
