Important Safety Messages

Always wear ANSI-ap-

proved goggles for 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.

• Before testing a vehicle, make

sure the transmission is in PARK

(automatic transmission) or

NEUTRAL (manual transmission)

and the 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 redily available.

• Never lay tools on the vehicle

battery.

• Always use caution when work-

ing around ignition coil, distribu-

tor cap, ignition wires, and spark

plugs. Components can produce

a High Voltage while engine is

running.

• Battery acid is caustic. If con-

tacted, rinse with water or neu-

tralize 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 PocketScan® 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 disconnect-

ing electrical components,

unless otherwise instructed.

Some vehicles are equipped with

safety air bags. Follow vehicle ser-

vice manual cautions when working

around air bag components or

wiring.

WARNING!

A vehicle airbag can open

for several minutes after

the ignition has been

turned off.

• Always follow vehicle manufac-

turer’s warnings, cautions, and

service procedures.

are currently used for state emis-

sions tests.)

PocketScan® Code Reader

Features

Read Codes

Reading Diagnostic Trouble Codes

allows the PocketScan®

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 Trou-

ble 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 Malfunction

Indicator Lamp on vehicle should

be ON indicating a possible

emissions problem.

9If 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:

| CP9125 | User guide | 7

Indicates the Malfunction Indica-

tor Lamp should be off and there

should be no emission problems.

9Some manufacturers will turn

the MIL off if a certain number

of drive cycles occur without the

same fault being detected.

9Diagnostic 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.

Inspection/Maintenance Monitors

(I/M Monitors

The I/M Monitors (Inspection /

Maintenance) function displays a

SNAPSHOT of the operations for the

Emission System.

9After a specific amount of drive

time (each monitor has specific

driving conditions and time

required), the computer’s “moni-

tors” will decide if the vehicles

emission system is working

correctly.

9Some 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.

• Monitors Viewed:

• Monitor Status:

Status Description

Ready Vehicle was driven enough under proper

conditions to complete the monitor.

Inc (Incomplete) Vehicle was not driven

enough under proper conditions to com-

plete the monitor.

• Monitors may be cleared by:

•Using the erase codes function.

• Disconnected or discharged

battery (on some vehicles.)

• Computer module losing

power (on some vehicles.)

Reading Diagnostic Trouble

Codes and Data

WARNING!

Avoid cooling fan. Fan

may turn on during test.

1. Turn ignition key to the OFF

position.

8|User guide | CP9125 |

2. Locate and plug in data link

connector (DLC).

NOTE: The data link connector

should be located under the

dashboard on the driverside of

the vehicle. If the data link con-

nector is not located under the

dashboard as stated, a label

describing the location of the

data link connector should be

there.

3. Observe display toggles between

“Pocket” and “Scan”.

NOTE: For a correct reading for

diagnostic trouble codes and I/M

monitor status, ignition key must

be in the ON position and engine

does not require starting. To get

a correct reading for MIL status,

engine must be started.

4. Start engine.

5. Press and release key.

NOTE: If diagnostice trouble

codes (DTCs) are already being

displayed from a previous read

operation, press and hold

for 3 seconds and release.

6. Observe a moving * on display.

NOTE: If “No Link” message

displays, cycle ignition key to the

OFF position for 10 seconds,

then back ON and repeat “Read-

ing Diagnostic Data” procedure.

7. View codes on display.

NOTE: If

there are no codes present, the

tool will display “0 Codes” and

proceed to display MIL Status

when is pressed.

• To view codes, press and

release .

• If the code is a pending code,

pd will be displayed.

8. View MIL status:

• Press and release .

9. View I/M monitors that are

incomplete.

• Press and release .

| CP9125 | User guide | 9

NOTE: If there are no more

I/M monitors that are incom-

plete, the tool will then

display ready monitors when

is pressed.

10.View I/M monitors that are

ready.

• Press and release .

NOTE: Pressing will

scroll up to review diagnostic

trouble codes and data.

Holding down for 3

seconds will read diagnostic

trouble codes and data again.

Erasing Diagnostic Trouble

Codes and Data

Erasing allows the PocketScan®

code reader to delete the codes and

IM monitor status from the vehicle’s

computer modules.

NOTICE

Only erase diagnostic data

after checking

system completely and

writing down results.

WARNING!

Avoid cooling fan. Fan

may turn on during test.

1. Turn ignition key to the OFF

position.

2. Locate and plug in data link

connector (DLC).

NOTE: The data link connector

should be located under the

dashboard on the driverside of

the vehicle. If the data link

connector is not located under

the dashboard as stated, a label

describing the location of the

data link connector should be

there.

3. Observe display toggles between

“Pocket” and “Scan”.

4. Turn ignition key to the ON

position leaving engine off.

NOTE: Make sure that the igni-

tion key is ON and NOT in the

accessory position.

5. Press and hold for 3 sec-

onds and release.

6. Observe “ERASE?” displays.

7. Press and hold for 3 sec-

onds and release.

8. Observe a moving — on display.

NOTE: If a “NO LINK” message

displays, cycle ignition key to the

OFF position for 10 seconds,

ing Diagnostic Data” procedure.

9. Observe “DONE” displays.

NOTE: If the problem causing

diagnostic trouble code(s) still

exists, the code will return. The

diagnostic trouble code may

return immediately or may

return after vehicle has been

driven.

NOTE: Pressing will read

diagnostic trouble codes and

data and holding will erase

results again.

Diagnostic Trouble Codes

This section contains the J2012

Diagnostic Trouble Codes (DTCs) as

defined by the Society of Automotive

Engineers (SAE).

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.

DTC definitions have been assigned

or reserved by the Society of Automo-

tive Engineers (SAE) to direct to

proper service area(s).

Codes not assigned or reserved by

the SAE are reserved for the manu-

facturer and referred to as Manufac-

turer Specific DTCs.

Remember:

•Visual inspections are important!

•Problems with wiring and connec-

tors 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 opera-

tion might even make the com-

| CP9125 | User guide | 11

puter show a known good sen-

sor as being bad!
