Chrysler Operations This chapter explains how to begin the scan tool s basic setup and test functions. This information is specific to Chrysler vehicles. For general scan tool functionality, see the user s manual appropriate to your diagnostic tool. For additional information on Chrysler vehicles, see the following sections: Chrysler Testing on page 13 Chrysler and Jeep Data Parameters on page 211 Chrysler Communications Problems on page 707 TEST THE SAME VEHICLE AND SYSTEM? YES NO IDENTIFY THE VEHICLE SELECT A SYSTEM SELECT VEHICLE OPTIONS CONN ECT TO THE VEHICLE MAIN MENUS SYSTEM TESTS CODES & DATA FUNCTIONAL TESTS Figure 3-1 Basic Chrysler test routine 3.1 Identifying a Vehicle Many late-model vehicles have an automatic vehicle identification (ID) function that identifies the test vehicle based on information transmitted on the serial data stream. For others, the vehicle must be manually identified by entering specific vehicle identification number (VIN) characters into the scan tool. 5
Identifying a Vehicle 3.1.1 Manual Identification You must manually enter the vehicle ID for all 1995 and earlier vehicles. You may also manually identify automatic ID systems. Note the following when manually identifying Chrysler vehicles: Because of midyear manufacturing changes in engine computer systems, you should always enter a new identification when you test a different vehicle, even when two vehicles are the same year, model, and have the same engine and accessories. Models with Mitsubishi-built engines must be identified as an Asian Import. The following models were built using 1986 logic modules: Some 1987 Sundance and Shadow (P-body) models with turbocharged engines Some 1987 Omni, Horizon, and Charger (L-body) Vehicle identification for these models should be entered into the scan tool as 1986 models (10th VIN character G for 1986, instead of H for 1987). A 1986 logic module can be identified by the MAP sensor mounted on the module case. The 1987 logic modules use MAP sensors mounted in the engine compartment. To test Jeep vehicles with the US Domestic software: 1990 and later select CHRYSLER from the manufacturer selection menu 1989 and earlier select JEEP from the manufacturer selection menu Many 1983 and later Chrysler imports, except Maserati TC, are tested with the Asian Import software. The US Domestic software does not test these vehicles, which often have Diamond Star imprinted on the body label attached to the firewall. The vehicle ID process begins from the Software Confirmation menu ( To manually ID a vehicle: on page 6). >CHRYSLER DATABASE (1990-2004) V 9.0 PRESS Y TO CONTINUE Figure 3-2 Sample Software Confirmation menu z To manually ID a vehicle: 1. Press Y to confirm the software selection. 2. Do one of the following: 1989 and earlier: Select CHRYSLER (Figure 3-3).

For instance, select ENGINE and a Vehicle Options menu displays (Figure 3-9). SCROLL TO SELECT VEHICLE OPTIONS: >A/T WITH A/C A/T WITHOUT A/C M/T WITH A/C Figure 3-9 Sample Chrysler Vehicle Options menu This menu describes whether the vehicle has an automatic or standard transmission, and if it has air conditioning. Other menus are similar and all require a selection. 8
3.3 Connecting to the Vehicle Once a vehicle has been identified and a system has been selected, a scan tool connection message instructs you to use the vehicle test adapters supplied to connect the scan tool for testing (Figure 3-10). CONNECT OBD-II K13 ADAPTER TO CONNECTOR LOCATED UNDER LEFT SIDE OF DASH, NEAR HOOD RELEASE. PRESS Y TO CONTINUE. Figure 3-10 Sample Chrysler connection message Each test adapter plugs into a specific vehicle diagnostic connector and attaches to one end of the data cable. The other end of the data cable attaches to the scan tool. The following adapters are available to test Chrysler vehicles: CHRY-1 (MT2500-30) engine test adapter (except LH cars) CHRY-2 (MT2500-31) body, ABS, transmission, and LH-car engine test adapter MITSU-1 (MT2500-55) Mitsubishi engine and transmission test adapter (used for Avenger, Sebring, and Talon) OBD-II (MT2500-46) 16-pin adapter for vehicles with the 16-pin OBD-II connector The K-7 device must be installed into the OBD-II adapter when used with MITSU-1 for the Avenger, Sebring, and Talon. The K-13 device must be installed for all other Chrysler applications Figure 3-11 MT2500-30 CHRY-1 adapter Figure 3-12 MT2500-31 CHRY-2 adapter Figure 3-13 MT2500-55 MITSU-1 adapter Figure 3-14 MT2500-46 OBD-II adapter 9
Connecting to the Vehicle The CHRY-1 test adapter has a socket for connecting the battery power or cigarette lighter power cables. A power cable is not required with the CHRY-2 and the OBD-II test adapters.table 3-2 contains connector locations for Chrysler vehicles.
