Engine Controls - Tests W/codes - Body Control Computer Plymouth Voyager II

DESCRIPTION

The body control computer system consists of a combination of modules that communicate over the Chrysler Collision Detection (CCD) bus system. Through the CCD bus, information related to the operation of vehicle components and circuits is relayed to the appropriate system module(s). Each module receives the same component information. This reduces the complexity of vehicle wiring and size of wiring harness.

The following body control computer systems are covered in this article: electronic instrument cluster, electro/mechanical instrument cluster, automatic door locks, compass/mini-trip module, illuminated entry, headlights, key-in light system, liftgate release, seat belt warning light system and intermittent wipers. System failures within these systems can be diagnosed via the CCD bus diagnostic connector using Chrysler Diagnostic Readout Box II (DRB-II) tester.

OPERATION

Diagnostic test procedures are designed to detect system faults as quickly as possible. Body and chassis fault codes are accessed through CCD bus diagnostic connector. CCD bus diagnostic connector is located under left side of dash. (Scheme 32) DRB-II tester is used to access information from CCD bus.

Scheme 32

The body control computer, sometimes referred to as body controller, is located under left side of instrument panel. Body control computer stores odometer information for electronic instrument cluster and electro/mechanical instrument cluster display and provides power and ground for a variety of systems. Systems are monitored by body control computer through voltage drops.

CCD BUS

The CCD bus is a twisted pair of wires traveling from module to module receiving and delivering coded information. The code identifies the message and its importance. When multiple messages attempt to access CCD bus at once, code assigns priority ranking. The 2 twisted wires used by the CCD bus system are called Bus "+" and Bus "--". Both wires carry approximately 2.5 volts. The network consists of some modules with "bias" and some with "termination".

Bias is the part of the voltage divider network which places both bus "+" and bus "--" at 2.5 volts. Termination is the part of the circuitry required to complete the voltage divider network and also provide some electromagnetic protection for the CCD bus. Terminations in all CCD applications have approximately 120 ohms resistance.

ELECTRONIC INSTRUMENT CLUSTER

The electronic instrument cluster includes a digital speedometer, odometer, oil pressure gauge, coolant temperature gauge, fuel gauge, voltage gauge and a series of warning lights. Electronic instrument cluster receives all of its information for its displays from the body controller and the Powertrain Control Module (PCM) by means of CCD bus system.

SELF-DIAGNOSTIC SYSTEM

Use diagnostic tests listed in BODY CONTROL COMPUTER TESTS DIRECTORY table when using DRB-II.

PRETEST INSPECTION

Before proceeding with diagnosis, the following precautions must be followed

1. Vehicle must have a fully charged battery and functional charging system.
2. Always start at TEST 1A: IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS. Starting with any other test may result in incorrect results.
3. Only perform test steps indicated. It is NOT necessary to perform all steps in a test.

5. Always perform TEST VER-1 after repairs are completed.
6. Turn ignition switch to OFF position before disconnecting or connecting components.
7. At end of each test step, reconnect all wires and install any components removed for testing.
8. Use extreme care when connecting or disconnecting wiring during testing to prevent accidental grounding or shorting.
9. DO NOT use a test light in place of a voltmeter.
10. Always disconnect DRB-II after use.
11. Always disconnect DRB-II before charging battery.

PROCEDURE

Note. Before proceeding with diagnosis, certain precautions must be followed. See PRETEST INSPECTION under SELF-DIAGNOSTIC SYSTEM.

8. If voltage is more than 10 volts, check voltage on Blue BCM connector terminal No. 6, fused ignition feed run/start circuit (Dark Blue/White wire). If voltage is not more than 10 volts, repair Dark Blue/White wire as necessary. Perform TEST VER-1.
9. If voltage is more than 10 volts, turn ignition off and change DRB-II to ohmmeter mode. Check resistance of Blue BCM connector terminal No. 19, ground circuit (Black/Light Green wire). If resistance is more than 15 ohms, repair open to ground in Black/Light Green wire. Perform TEST VER-1.
10. If resistance is less than 15 ohms, check resistance of BCM case ground. If resistance is more than 5 ohms, repair BCM case ground as necessary. Perform TEST VER-1. If resistance is less than 5 ohms, replace BCM. Perform TEST VER-1.

TEST 14A - NOT RECEIVING BUS MESSAGES CORRECTLY

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section.

1. Using DRB-II, indicate whether vehicle is equipped with specific module. Turn ignition off. Disconnect Transmission Control Module (TCM), if equipped. TCM is located on left side of engine compartment, near cowl. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace TCM. Perform TEST VER-1.
2. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Powertrain Control Module (PCM). PCM is located between data link connector and battery, on fenderwell. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace PCM. Perform TEST VER-1.
3. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Controller Anti-Lock Brake (CAB) module, if equipped. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace CAB module. Perform TEST VER-1.
4. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Mechanical Instrument Cluster (MIC) or Electronic Instrument Cluster (EIC). Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace MIC or EIC. Perform TEST VER-1.
5. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Vehicle Theft Alarm (VTA) module, if equipped. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace VTA module. Perform TEST VER-1.
6. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect compass/mini-trip module, if equipped. Compass/mini-trip module is located at center of roof, above visors. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace compass/mini-trip module. Perform TEST VER-1.
7. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off. Disconnect auto temperature control head, if equipped. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace auto temperature control head. Perform TEST VER-1.
8. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Body Control Module (BCM), if equipped. BCM is located behind right knee panel below dashboard.
9. Turn ignition on. If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace BCM. Perform TEST VER-1. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, replace DRB-II cable or cartridge as necessary. Perform TEST VER-1.

VERIFICATION PROCEDURE VER-1

1. Ensure ignition is off and DRB-II is connected. Turn ignition on. If DRB-II screen is blank, go to TEST 2A. If DRB-II screen is not blank, go to next step.
2. If there is a bus failure message on DRB-II, go to TEST 1A. If there is no bus failure message on DRB-II, select module in question. If DRB-II shows NO RESPONSE, go to TEST 1A.
3. If DRB-II does not show NO RESPONSE, inspect vehicle for original complaint. If original complaint is present, go to TEST 1A. If original complaint is not present, repair is complete.
