Do the Idle Learn Procedure
The idle learn procedure must be done on all 2008
MDX models at the TQI after the No. 4 fuse is installed
(see Install the Fuses in this bulletin.) If the idle learn
procedure is not done or is done incorrectly, the engine
may have an erratic idle.
NOTE: If you have not reset the AcuraLink control unit,
do that first.
1. Make sure all electrical items (A/C, radio, rear
window defogger, lights, etc.) are off.
2. Start the engine, and let it reach operating
temperature (the cooling fans cycle twice).
3. Let the engine idle for 10 minutes with the throttle
closed.
NOTE: Idle speed adjustment is done by the ECM/
PCM; there is no adjustment screw.
So that the PCM can learn the engine idle
characteristics, also do the idle learn procedure
whenever you do any of the following:
• Disconnect the battery.
• Replace the PCM, or unplug its connectors.
• Reset the PCM with the HDS.
• Remove the Main (120 A) and Backup fuses.
• Remove either of the wires from the under-hood
fuse/relay box terminal.
• Disconnect any of the connectors from the back of
the under-hood fuse/relay box.
• Disconnect the connector between the engine
compartment wire harness and the PCM wire
harness.
NOTE: Idle learn does not need to be repeated after
you erase DTCs.
Do the CKP-Pattern Learn Procedure
To ensure proper engine operation, do the CKP-
pattern learn procedure after doing the idle learn
procedure. Do this procedure on a level road during the
TQI test-drive. The procedure consists of a low-rpm
and a high-rpm pattern learn. Make sure you do the
low-rpm pattern learn first.
1.
Low-rpm Pattern Learn
: Shift to 2 or D3, and
decelerate with the throttle fully closed from
2,500 rpm to 1,000 rpm.
2.
High-rpm Pattern Learn
: With the transmission in
the sequential sportshift mode, shift to 1, and
decelerate with the throttle fully closed from
5,000 rpm to 3,000 rpm.
Check/Clean the Front Grilles
The new grilles’ upper and lower shields have dark
silver satin plating. Fingerprints can only be removed
using a cleaner. Use common spray-on glass cleaner
or mild soap to clean the plating.
Complete the Personalized Settings Check Sheet
(To Be Done by Sales Staff)
Sales staff will ask the client to complete a check sheet
specifying their preferences for the personalized
settings in the MID. While the client is in the finance
and insurance department, sales staff will program the
features that will likely be set only once; when sales
staff are ready to deliver the new vehicle to the client,
they will then review and program the features that the
client is likely to change often.
