Material required: – Remote Car Starter – Xpresskit : XK05-PKT2 or Bypasskit :PKT2 – One 5-wire relay for auto lamp circuit Key required for programming: 1 Average installation time: 2.5 hours Difficulty level: Medium 2.0 Preparation: -Remove the driver’s side under dash, as well as the knee airbag bolts. Move the Airbag aside, but DO NOT DISCONNECT the Airbag connector in order to avoid setting any vehicle codes. -Remove the driver’s side floor heating duct, in order to access the vehicle IMI & IMO wires easily. 3.0 Installation: The remote car starter will be installed in a conventional manner even if the car is equipped with the Smart Key “Push-to-Start” system. 3.01 Main Ignition Harness Connection: Most of the connections will be done behind the Fuse box. This fuse box is located under the driver side underdash. Also, the vehicle’s TACH wire can be found inside vehicle, as per diagram below and it is suggested to use this wire for the remote start tach source. The remote start hood pin switch wire is the only wire which must be run into the engine compartment for safety. Accessory (+): White Ignition 1 (+): Pink Ignition 2 (+): Light Green Starter (+): Grey Tach: Black 3.02 Wiring location for the Bypasskit XK-05 PKT2: The connection for the XK05-PKT2 will be done on the driver side under dash. The wires required are from a 5 wires harness coming from behind the heater module, high above the gas pedal near the firewall. The five wires in this harness are as follows: Blue: transponder IMI (Immobilizer in) wire, which gets cut in two and wired in series. The bottom-half wire connects to the kits Violet/White wire and the top-half wire connects the kits Violet wire. Green: transponder IMO (Immobilizer out) wire, which gets wired in parallel with the kits Orange wire. White/Black, White & Orange… these wire are not used for installation The GREEN LED output wire from the XK05-PKT2 is not required for this installation. The vehicle LED does come on during remote start. 3.03 Wiring location for door locks and factory alarm control: The wires to control the factory alarm and the door locks are located behind the driver’s kick panel. These wires must receive negative pulses. It is mandatory to disarm the OEM alarm system before remote start sequence Grey Unlock Wire : A double pulse unlock (-) output is required to disarm and unlock all doors. The first unlock (-) pulse disarms OEM alarm and unlocks driver’s door, the second pulse will unlock all other doors. In order to disarm the OEM alarm when remote starting, this GREY wire requires a pulse before start, which unlocks the driver’s door. So, if the remote systems unlock output does offer a pulse before start, then connect both the unlock and disarm (-) output wires to the vehicle’s GREY unlock wire. Brown Lock Wire : In order to lock and arm the OEM alarm system a (-) pulse is required for the vehicle’s BROWN lock wire. If the vehicle’s ignition on the alarm will not arm, if locking with remote.

The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter . Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi). Cause The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil. Correction
