2. 6 pin and 1 pin DLC: connect a suitable jumper wire from the self test input (STI) terminal 1 pin DLC
(single lead, shell color gray or black) to ground.
3. Reading Key On, Engine Off (KOEO) DTCs: Warm engine to normal operating temperature. Turn the
ignition key off and wait 10 seconds. Now turn the ignition key to run.
DTC indication will begin on dashboard MIL. The dashboard MIL will flash KOEO DTCs first, then a
separator code, followed by Continuous DTCs (see Figure M-2). For 3-digit DTCs the first set of MIL
flashes will equal the 100s digit. After a 2.0 second pause, the second set of flashes will equal the 10s
digit. After another 2.0 second pause, the third set of flashes will equal the 1s digit. Then a 6.0-9.0
second pause between the separator code and KOEO or Continuous DTCs will occur. If there are 2 or
more DTCs of the same type, there will be a 4.0 second pause between each DTC. After recording
DTCs, turn off ignition switch and disconnect jumper lead from DLC.
4. Reading Key On, Engine Running (KOER) DTCs: Warm engine to normal operating temperature.
Turn the ignition key off and wait 10 seconds. Now start the engine.
5. DTC indication will begin on dashboard MIL. Rotate steering wheel 1/2 turn, depress and release brake
pedal. If a single MIL flash occurs, depress and release throttle pedal. Wait for PCM to exercise all
outputs. The dashboard MIL will flash KOER DTCs. For 3-digit DTCs the first set of flashes will equal
the 100s digit. After a 2.0 second pause, the second set of flashes will equal the 10s digit. After another
2.0 second pause, the third set of flashes will equal the 1s digit. If there are 2 or more DTCs, there will be
a 4.0 second pause between each DTC. After recording DTCs, turn off ignition switch and disconnect
jumper lead from DLC.
