I/M READINESS TESTING

■ See page 30 for procedures to erase DTCs from the vehicle's on-

board computer.

■ Write the codes down on a piece of paper for reference before

erasing.

3. After the erase procedure is performed, most of the Monitor icons

on the CanOBD2&1 Scan Tool’s display will be flashing. Leave the

CanOBD2&1 Scan Tool connected to the vehicle, and perform a Trip

Drive Cycle for each "flashing" Monitor:

Misfire, Fuel and Comprehensive Component Monitors run

continuously and their icons will always be on solid, even

after the erase function is performed.

■ Each DTC is associated with a specific Monitor.Consult the vehi-

cle's service manual to identify the Monitor (or Monitors) associ-

ated with the faults that were repaired.Follow the manufacturer's

procedures to perform a Trip Drive Cycle for the appropriate

Monitors.

■ While observing the Monitor icons on the CanOBD2&1 Scan

Tool’s display, perform a Trip Drive Cycle for the appropriate

Monitor or Monitors.

WARNING: If the vehicle needs to be driven in order to perform a

Trip Drive Cycle, ALWAYS have a second person help you. One

person should drive the vehicle while the other person observes

the Monitor icons on the CanOBD2&1 Scan Tool for Monitor RUN

status. Trying to drive and observe the CanOBD2&1 Scan Tool at

the same time is dangerous, and could cause a serious traffic

accident.

4. When a Monitor's Trip Drive Cycle is performed properly, the

Monitor icon on the CanOBD2&1 Scan Tool’s display changes from

"flashing" to "solid,” indicating that the Monitor has run and finished

its diagnostic testing.

■ If, after the Monitor has run, the MIL on the vehicle's dash is not

lit, and no stored or pending codes associated with that particu-

lar Monitor are present in the vehicle's computer, the repair was

successful.

■ If, after the Monitor has run, the MIL on the vehicle's dash lights

and/or a DTC associated with that Monitor is present in the vehi-

cle's computer, the repair was unsuccessful. Refer to the vehi-

cle's service manual and recheck repair procedures.
