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.
Circuit Description
The ignition mode switch has 2 contact buttons.
The upper button, with a circle indicator on it, that starts the engine if the brake pedal is applied.
The lower button has two indicators on it, O and ACC. This button cycles the ignition through the following modes
- OFF This is the normal state upon entering the vehicle, and can also be reached from any other mode by depressing the button. The O indicator illuminates.
- Accessory This mode can be reached from the Off state by depressing the button. The ACC indicator illuminates.
- ON with the engine OFF This state can be reached from the Off or Accessory modes by depressing the button for about 5-6 seconds. The upper LED illuminates.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
- 1: This step insures that the battery, and the vehicle primary power and ground systems are functioning correctly.
- 4: Lack of communication may be due to a particular malfunction of a serial data circuit. The link to "Data Link References" will provide a list of modules and the associated data network no communication diagnostic link.
| Step | Action | Yes | No |
|---|---|---|---|
| 1 | Perform the following preliminary inspections: Ensure that the battery is fully charged. Refer to Battery Inspection/Test in Engine Electrical. Ensure that the battery cables are clean and tight. 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 in Wiring Systems. 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 | Turn ON the ignition, with the engine OFF. Is the NO FOB DETECTED message displayed on the driver information center (DIC)? | Go to Key Fob Not Detected in Keyless Entry | Go to Step 4 |
| 4 | Turn ON the ignition, with the engine OFF. Attempt to establish communication with all of the control modules on the vehicle. Refer to Data Link References in Computer/Integrating Systems for the modules you should expect to observe. Does the scan tool communicate with all of the expected vehicle control modules? | Go to Step 5 | Go to Data Link References in Computer/Integrating Systems |
| 5 | Attempt to start the engine. Does the engine crank? | Go to Step 6 | Go to Symptoms - Engine Electrical in Engine Electrical |
| 6 | Attempt to start the engine. Does the engine start and idle? | Go to Step 7 | Go to Engine Cranks but Does Not Run in Engine Controls - 3.6L (LY7) or Go to Engine Cranks but Does Not Run in Engine Controls - 4.6L (LH2) |
| 7 | IMPORTANT: Do NOT clear any DTCs unless instructed by a diagnostic procedure. Diagnose the DTCs in the order that the DTCs appear on the scan tool or mis-diagnosis may occur. If multiple powertrain DTCs are stored, diagnose the DTCs in the following order: Component level DTCs, such as sensor DTCs, solenoid DTCs, and relay DTCs. System level DTCs, such as misfire DTCs, EVAP system DTCs, and fuel trim DTCs. Advance to the List All DTCs screen on the scan tool.Does the scan tool display any DTCs? | Go to Diagnostic Trouble Code (DTC) List - Vehicle | Go to Step 8 |
| 8 | Is the customers concern with inspection/maintenance (I/M) testing? | Go to Inspection/Maintenance (I/M) System Check in Engine Controls - 3.6L (LY7) or Go to Inspection/Maintenance (I/M) System Check in Engine Controls - 4.6L (LH2) | Go to Symptoms - Vehicle |
| IMPORTANT |

DTC Symptom Description
A DTC symptom is a 2-digit number which adds additional detail to a DTC. The DTC symptom provides additional information without requiring a large increase in the number of new DTCs.
DTC Symptom Categories
The DTC symptom is made up of 2 alphanumeric digits. The first digit following the DTC indicates the DTC symptom category. There are 16 possible categories available in the range of 0 through the letter F. Currently there are 8 categories in use, 0 through 7. These 8 categories together with their definitions are given below.
| Category Number | Category Name | Category Description |
|---|---|---|
| 0 | General Electrical Failures | This category includes standard wiring failure modes, direct current quantities related by Ohm's Law and quantities related to amplitude, frequency or rate of change, and wave shape. |
| 1 | Additional General Electrical Failures | This category includes the overflow from the previous category. |
| 2 | FM/PWM (Frequency/Pulse Width Modulated) Failures | This category includes faults related to frequency modulated and pulse width modulated inputs and outputs of the electronic control module (ECU). This category also includes faults where position is determined by counts. |
| 3 | ECU Internal Failures | This category includes faults related to memory, software, and internal electrical circuitry; requiring ECU replacement. |
| 4 | ECU Programming Failures | This category includes faults related to operational software, calibrations, and options, remedied by programming the ECU. |
| 5 | Algorithm Based Failures | This category includes faults based on comparing two or more input parameters for plausibility or comparing a single parameter to itself with respect to time. |
| 6 | Mechanical Failures | This category includes faults detected by inappropriate motion in response to an ECU controlled output. |
| 7 | Bus Signal/Message Failures | This category includes faults related to bus hardware and signal integrity. This category is also used when the physical input for a signal is located in one ECU and another ECU diagnoses the circuit. |
| 8-F | Reserved by Document | Not in use at this time. |
DTC Symptom Description
DTC Symptom Subtypes
The second digit of the DTC symptom is the subtype of the DTC symptom. These subtypes and their categories, together with their definitions, are given in the following table. DTC symptom 00 is a special case. If 00 is displayed, only the base code number and its description apply. Information regarding the fault will be provided in the code setting criteria.
Example
The DTC symptoms associated with each DTC provide more information about the fault that caused that DTC. An example of a DTC displayed can be B1451 05 where the B1451 is the DTC, and 05 after the space represents the DTC symptom. While the DTC indicates that the fault is in the accessory power circuit, this DTC symptom indicates the circuit is shorted to battery or open. Another possible symptom for this code is B1451 02, where B1451 indicates the accessory power circuit, and 02 indicates the circuit is shorted to ground.
