Innova 5610: Plugging and Scanning Codes (Code Retrieval Procedures)
To guide you on first plugging in your device and scanning codes while using the Innova 5610.
Code Retrieval Procedures
Always refer to the vehicle's service manual for detailed testing instructions. Never replace a part based only on the DTC's code definition. Each DTC has a unique set of testing procedures, instructions, and flow charts that must be followed to confirm the location of the problem.
Always observe safety precautions whenever working on a vehicle and check your vehicle thoroughly for hazards before performing any test.
Step 1 - Turn the Ignition off.
|Make sure to turn off your vehicle's ignition.|
Step 2 - Locate the vehicle's 16-pin Data Link Connector (DLC).
|Some DLCs have a plastic cover that must be removed before connecting the Scan Tool. If the Scan Tool is manually turned On, turn it off before connecting to the DLC.|
Step 3 - Connect the Scan Tool to the vehicle's DLC.
The cable connector is keyed and will only fit one way.
If you have problems connecting the cable to the DLC, rotate the connector 180°.
If you still have problems, check the DLC on the vehicle and on the Scan Tool to see if any pins look damaged.
Step 4 - Turn the ignition on. Do not start the engine.
|Turn on the Ignition but do not start the engine.|
Step 5 - When the Scan Tool is properly connected to the vehicle’s DLC, the unit itself will automatically turn 'On.'
If the unit does not power on automatically, it may indicate there is no power present at the vehicle’s DLC connector. Check the fuse panel and replace any burned-out fuses.
If replacing the fuse(s) does not correct the problem, consult the vehicle’s repair manual to identify the proper computer (PCM) fuse/circuit, and perform any necessary repairs before proceeding.
Step 6 - The Scan Tool automatically starts a check of the vehicle’s computer to determine which communication protocol it is using.
When the Scan Tool identifies the computer’s communication protocol, a communication link is established:
If the Scan Tool cannot link to the vehicle’s computer after three attempts, the message 'Contact Technical Support' will display.
- Select System Menu to return to the System Menu. If Global OBD2 is not supported, you may still use other systems such as ABS.
- Turn the ignition 'Off', and disconnect the Scan Tool.
- Contact Technical Support for assistance.
Step 7 - If the Scan Tool can automatically decode the Vehicle Identification Number (VIN) for the vehicle under test, the Confirm Vehicle screen will display.
If the Scan Tool cannot decode the Vehicle Identification Number (VIN) for the vehicle under test, the Select Vehicle screen will display. Proceed to step 8.
If the information shown is not correct for the vehicle under test, or if you wish to manually select the vehicle, select 'No', then proceed to step 9.
If the information shown is correct for the vehicle under test, select 'Yes', then proceed to step 10.
Step 8 - When No is selected from the Vehicle information screen, the Select Vehicle screen will display.
The 'Select Vehicle' screen lists the three most recently tested vehicles.
To select a new vehicle, select 'New Vehicle.' Proceed to step 9.
To use a previously tested vehicle, select the desired vehicle, then press ENTER ↵ to proceed to step 10.
Step 9 - When New Vehicle is chosen from the Select Vehicle screen, the Select Year screen will display.
Press the UP ▲, DOWN ▼, and ENTER ↵ buttons.
You will be prompted to select your vehicle's Year, Make, Model, Engine Size, and Transmission Type.
Step 10 - Refer to Display Functions for a description of display elements.
After approximately 10-60 seconds the Scan Tool will retrieve and display any Diagnostic Trouble Codes, Monitor Status, and Freeze Frame Data retrieved from the vehicle's computer memory.
The Scan Tool will display a code only if codes are present, if no codes are present, the message 'No Powertrain DTCs or Freeze Frame Data presently stored in the vehicle's computer' message will display.
If DTCs are retrieved and you are going to perform the repairs yourself, proceed by consulting your Vehicle’s Service Repair Manual for testing instructions, testing procedures, and flow charts related to retrieved code(s).
In the case of long code definitions, a small arrow is shown in the upper/lower right-hand corner of the display area to indicate the presence of additional information. If a definition for the currently displayed code is not available, an advisory message will show.
To prolong battery life, the Scan Tool automatically shuts 'Off' approximately three minutes after it is disconnected from the vehicle. The DTCs retrieved, Monitor Status, and Freeze Frame data (if any) will remain in the Scan Tool’s memory, and may be viewed at any time by turning the unit 'On.'
If the Scan Tool’s batteries are removed, or if the Scan Tool is re-linked to a vehicle to retrieve codes/data, any prior codes/data in its memory are automatically cleared.
Step 11 - Read and interpret Diagnostic Trouble Codes/system conditions using the display and the green, yellow and red LEDs.
The green, yellow, and red LEDs are used (with the display) as visual aids to make it easier to determine engine system conditions.
|Green LED – Indicates that all engine systems are 'OK' and operating normally. All monitors supported by the vehicle have run and performed their diagnostic testing, and no trouble codes are present. All Monitor icons will be solid and not flashing.|
Yellow LED – Indicates one of the following conditions:
A. A pending code is present – If the yellow LED is illuminated, it may indicate a Pending code is present. Check the display for confirmation. A pending code is confirmed by the presence of a numeric code and the word 'PENDING.'
|B. Monitor Not Run Status – If this display will show, then it means that no DTCs or Freeze Frame Data is presently stored in the vehicle's computer (indicating there are no DTCs present in the vehicle’s computer memory), but the yellow LED is illuminated, it may be an indication that some of the Monitors supported by the vehicle have not yet run and completed their diagnostic testing. Check the display for confirmation. All Monitor icons that are blinking have not yet run and completed their diagnostic testing; all Monitor icons that are solid have run and completed their diagnostic testing.|
|C. Red LED – Indicates there is a problem with one or more of the vehicle’s systems. The red LED is also used to indicate that DTC(s) are present. In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will be illuminated.|
Select Freeze Frame to view Freeze Frame data for the 'priority' DTC.
DTCs that start with 'P0', 'P2', and some 'P3' are considered Generic (Universal). All Generic DTC definitions are the same on all OBD2-equipped vehicles. The Scan Tool will automatically display the code definitions (if available) for Generic DTCs.
DTCs that start with 'P1' and some 'P3' are Manufacturer specific codes and their code definitions vary with each vehicle manufacturer.
Step 12 - To view Freeze Frame Data, press and release the Freeze Frame button, as necessary.
Each time DTC/FF is pressed and released, the Scan Tool will scroll and display the next DTC in sequence until all DTCs in its memory have been displayed.
Freeze Frame Data (if available) will display after DTC #1.
In OBD2 systems, when an emissions-related engine malfunction occurs that causes a DTC to set, a record or snapshot of engine conditions at the time that the malfunction occurred is also saved in the vehicle’s computer memory. The record saved is called Freeze Frame data. Saved engine conditions include, but are not limited to engine speed, open or closed loop operation, fuel system commands, coolant temperature, calculated load value, fuel pressure, vehicle speed, air flow rate, and intake manifold pressure.
If more than one malfunction is present that causes more than one DTC to be set, only the code with the highest priority will contain Freeze Frame data. The code designated '01' on the Scan Tool display is referred to as the priority code, and Freeze Frame data always refers to this code. The priority code is also the one that has commanded the MIL to turn on.
The retrieved information can be uploaded to a Personal Computer (PC) with the use of optional software as well.
