CKP Pattern Clear/Learn Procedure
2005~06 MDX
NOTE:
^
The ECT must be at least 176 degrees F (80 degrees C).
^
Before doing this procedure, check "PULSER F/B LEARN" and "PULSER F/B LEARN (HIGH RPM)" in the DATA LIST with the HDS. If both
values show N/A, this procedure is not needed.
^
If only PULSER FIB LEARN (HIGH RPM)" shows N/A, skip steps 7 through 9.
1. With the engine stopped, clear the CKP pattern.
2. Turn the ignition switch to LOCK (0).
3. Turn the ignition switch to ON (II), and wait 30 seconds.
4. Test-drive the vehicle on a level road: Decelerate with the throttle fully closed from an engine speed of 2,500 rpm to 1,000 rpm with the A/T in 2.
5. Stop the vehicle, but keep the engine running.
6. Check PULSER FIB LEARN in the DATA LIST with the HDS. If it is NOT COMPLETED, go to step 4. If it is COMPLETED, go to step 7.
