ALL INFINITI MODELS; FLUID LEAK REPAIR SERVICE INFORMATION
The following information is provided to help ensure correct diagnosis and repair of fluid leaks. All fluid leaks, when properly diagnosed, should be repaired (whether under warranty or customer pay) to ensure proper vehicle operation.
VARIOUS INFINITI MODELS; INTELLIGENT KEY NOT DETECTED / ENGINE WILL NOT START
Intelligent Key (I-Key) systems on the Applied Vehicles use two (2) different Radio Frequencies (RF) that are similar to other wireless devices; 315 MHz and 433 MHz.
In the event another wireless device (e.g. aftermarket alarm system) is transmitting at the same time as an I-Key, it can interfere with the I-Key signals being received by the BCM.

Basic Diagnosing of TPMS/LTPWS systems.
Aftermarket wheels.
Inflating/deflating tires with TPMS/LTPWS sensors.
Moving TPMS/LTPWS wheel assemblies from one vehicle to another and TPMS/LTPWS sensor registration.

-REVISED- 2011-2013 INFINITI QX56; WHINE NOISE FROM ENGINE AREA
A whine type noise is coming from the Bank 2 (B2) side of the timing chain system.
• The noise is best heard from the high pressure fuel pump area.
• The noise should increase in frequency with engine speed (RPM).
• If the noise does not increase with engine speed, the timing chain system may not be the cause.
Refer to the appropriate section of the Electronic Service Manual (ESM) for further diagnosis.
ALL INFINITI MODELS 2009 AND UP; CRUISE CONTROL WILL NOT SET AND DTC P0605 IS STORED
Improper adjustment or operation of the ASCD brake switch can cause the Automatic Speed Control Device (ASCD) to “not set” and/or DTC P0605 (ECM) to store.
If a malfunction in the ASCD system is detected, the “CRUISE” indicator may stay ON and the “SET” indicator may flash.
ALL INFINITI MODELS; LOCK/UNLOCK REQUEST BUTTON ON OUTSIDE DOOR HANDLE DOES NOT RESPOND
The “Lock / Unlock request buttons” that are located on the outside door handles of vehicles with Intelligent Key can be disabled (or enabled) through either the "Comfort & Conv." settings of the Audio/Visual/Navigation system, or through the “Combination Meter settings” depending on the vehicle model, year and trim level.
