2005-2009 Pontiac Montana SV6 Service & Repair Manual

2006 ACCESSORIES & EQUIPMENT Vehicle DTC Information - Terraza, Uplander & Montana SV6 DIAGNOSTIC INFORMATION AND PROCEDURES DIAGNOSTIC STARTING POINT - VEHICLE Begin the system diagnosis with Diagnostic System Check - Vehicle . The Diagnostic System Check - Vehicle will provide the following information:  The identification of the control modules which are not communicating through the serial data circuit.  The identification of any stored diagnostic trouble codes (DTCs) and their status. The use of the Diagnostic System Check - Vehicle will identify the correct procedures to begin vehicle diagnosis. These must be performed before system DTC or symptom diagnosis. DIAGNOSTIC SYSTEM CHECK - VEHICLE Test Description The numbers below refer to the step numbers on the diagnostic table. 1: This step ensures that the battery and the vehicle primary power and ground systems are functioning correctly. 3: Lack of communication may be due to a particular malfunction of a serial data circuit. The information in Scan Tool does not Communicate with Class 2 Device will provide a list of modules and the associated data network no communication diagnostic link. 4: A module that is operating in the incorrect power mode based on key position may cause other vehicle symptoms and/or DTCs to set. The information in Power Mode Mismatch will correct the condition before checking for module DTCs or symptoms. 8: This step ensures that all data link communication DTCs are diagnosed before system level DTCs. 9: This step ensures that all electronic control unit (ECU) internal DTCs are diagnosed before other system level DTCs. 10: This step ensures that all device voltage DTCs are diagnosed before other system level DTCs. Diagnostic System Check - Vehicle Step Action Yes No Perform the following preliminary inspections:  Ensure that the battery is fully charged. Refer to Battery Inspection/Test .  Ensure that the battery cables are clean and tight. 2006 Chevrolet Uplander 2006 ACCESSORIES & EQUIPMENT Vehicle DTC Information - Terraza, Uplander & Montana SV6 2006 Chevrolet Uplander 2006 ACCESSORIES & EQUIPMENT Vehicle DTC Information - Terraza, Uplander & Montana SV6

1  Inspect for any open fuses.  Inspect the easily accessible systems or the visible system components for obvious damage or conditions that could cause the symptom.  Ensure that the grounds are clean, tight and in the correct location.  Inspect for aftermarket devices that could affect the operation of the system. Refer to Checking Aftermarket Accessories .  Search for applicable service bulletins. Did you find and correct the condition? System OK Go to Step 2 2 Install a scan tool. Does the scan tool power up? Go to Step 3 Go to Scan Tool Does Not Power Up 3 1. Turn ON the ignition, with the engine OFF. 2. Attempt to establish communication with all of the control modules on the vehicle. Refer to Scan Tool Does Not Communicate with Class 2 Device for the modules you should expect to observe. Does the scan tool communicate with all of the expected vehicle control modules? Go to Step 4 Go to Scan Tool Does Not Communicate with Class 2 Device 4 1. Access the Power Mode parameter on the scan tool. 2. Rotate the ignition switch, operate the ignition mode switch, through all positions while observing the Power Mode parameter. Refer to Body Control System Description and Operation for a list of the power mode states that correspond with each switch position. IMPORTANT:  To ensure that retained accessory power (RAP) mode is inactive, if equipped, open the drivers door during the following step.  The engine may start during the following step. Turn OFF the engine as soon as you have observed the crank power mode. 2006 Chevrolet Uplander 2006 ACCESSORIES & EQUIPMENT Vehicle DTC Information - Terraza, Uplander & Montana SV6
