For safety, read, understand and follow all safety messages and instructions in manual before operating the PocketScanTM Code Reader.
Always refer to and follow safety messages and test procedures provided by manufacturer of vehicle and PocketScanTM Code Reader.
Signal Words Used:
! DANGER Indicates a possible hazardous situation which, if not avoided, will result in death or serious injury to operator or bystanders.
! WARNING Indicates a possible hazardous situation which, if not avoided, could result in death or serious injury to operator or bystanders.
! CAUTION
IMPORTANT
Indicates a possible hazardous situation which, if not avoided, may result in moderate or minor injury to operator or bystanders.
Indicates a condition which, if not avoided, may result in damage to test equipment or vehicle.
Important Safety Messages
•Always wear ANSI approved eye protection.
•Always operate vehicle in a well-ventilated area.
•Always keep people, tools and test equipment away from all moving or hot engine parts.
•Always make sure vehicle is in PARK (automatic transmission) or Neutral (manual transmission) and parking brake is set.
•Always block drive wheels and never leave vehicle unattended while testing.
•Always keep a fire extinguisher suitable for gasoline/ electrical/chemical fires readily available.
•Never lay tools on vehicle battery.

•Always use caution when working around ignition coil, distributor cap, ignition wires, and spark plugs. Components can produce a High Voltage while engine is running.
•Battery acid is caustic. If contacted, rinse with water or neutralize with a mild base (i.e. baking soda). If in eyes, flush with water and call a physician immediately.
•Never smoke or have open flames near vehicle. Vapors from gasoline and battery during charge are explosive.
•Never use the PocketScanTM Code Reader if internal circuitry has been exposed to moisture. Internal shorts could cause a fire and damage.
•Always turn ignition key OFF when connecting or disconnecting electrical components, unless otherwise instructed.
•Some vehicles are equipped with safety air bags. Follow vehicle service manual cautions when working around air bag components or wiring. Note, air bag can still open several minutes after ignition key is off.
•Always follow vehicle manufacturer’s warnings, cautions and service procedures.

PocketScanTM Code Reader Features
Read Codes:
Reading Diagnostic Trouble Codes allows the PocketScanTM Code Reader to read the codes from the vehicle’s computer modules.
• Diagnostic Trouble Codes: |

Diagnostic Trouble Codes are |
|
: |
|
|
used to help determine the cause |
|
|
|
|
|
|
|
|
|
of a problem or problems with a |
|
|
|
|
vehicle. Diagnostic Trouble Codes are set when a fault is present for a sufficient amount of time.
• Pending Codes: Pending Codes are also referred to as “continuous monitor codes” and “maturing codes.” Pending Codes occurs when the code has not occurred a specific number of times (depending on
vehicle,) causing the code to mature.

MIL Conditions:
MIL (Malfunction Indicator Lamp) Status displays the state of the vehicles computer module(s).
• MIL ON: Indicates that the |
|
|
|
MIL ON |
: |
||
Malfunction Indicator Lamp on |
|||
|
9 |
||
vehicle should be ON indicating |
|
|
|
|
|
||
a possible emissions problem. |
|
|
√ If the MIL Status is ON and the MIL is not illuminated with the engine running, then a problem exists in the MIL circuit.
•MIL OFF: Indicates the Malfunction Indicator Lamp should be off and there should be no emission problems.
MIL OFF 9:
√Some manufacturers will turn the MIL off if a certain number of drive cycles occur without the same fault being detected.
√Diagnostic Trouble Codes related to a MIL are erased from the computer’s memory after 40 warm-up cycles if the same fault is not detected.
5
Inspection / Maintenance Monitors (I/M Monitors):
The I/M Monitors (Inspection / Maintenance) function displays a SNAPSHOT of the operations for the Emission System.
√After a specific amount of drive time (each monitor has specific driving conditions and time required), the computer’s “monitors” will decide if the vehicles emission system is working correctly.
√Some states MAY NOT require all monitors listed to be “Ready” to pass the emissions test. Check with state testing site for exact requirements. All states will fail a vehicle that has the “MIL Light” lit at time of test.

Diagnostic Trouble Codes (DTCs)
This section contains the J2012 Diagnostic Trouble Codes (DTCs) as defined by the Society of Automotive Engineers (SAE). Diagnostic Trouble Codes (DTCs) are recommendations not a requirement. Manufacturers may not follow these, but most do.
Check vehicle’s service manual for DTC meaning if the code(s) you are getting does not make sense.
Diagnostic Trouble Code (DTCs) definitions have been assigned or reserved by the Society of Automotive Engineers (SAE) to direct to proper service area(s).
Codes not assigned or reserved by the Society of Automotive Engineers (SAE) are reserved for the manufacturer and referred to as Manufacturer Specific Diagnostic Trouble Codes (DTCs).
Remember:
•Visual inspections are important!
•Problems with wiring and connectors are common, especially for intermittent faults.
•Mechanical problems (vacuum leaks, binding or sticking linkages, etc.) can make a good sensor look bad to the computer.
•Incorrect information from a sensor may cause the computer to control the engine in the wrong way. Faulty engine operation might even make the computer show a known good sensor as being bad!
NOTE: Additional DTC definitions can be obtained from the CD supplied. thereIf are any problems operating the supplied CD contact Customer Service
at 1(800) 228-7667.
