ION L4-2.2L VIN F (2004)
charts. Some vehicles produced after VIN 4Z160000 have already had the resistance added to the turn signal circuit within the main body
wiring harness. These main body wiring harnesses are identified with pink tape on the passenger side tail lamp harness in the trunk.
^
For all 2003 model year vehicles and 2004 model year vehicles built prior to VIN 4Z160000 refer to Chart A.
^
For 2004 model year vehicles built after and including VIN 4Z160000 refer to Chart B.
Important:
Perform steps 12-16 Only if required in Chart A or Chart B.
12.
Locate mounting hole for resistor (3) on both the passenger and driver side. This hole is on the vertical metal between the radiator core support
and the frame rail, just outboard of the radiator/condenser assembly. (Driver's side shown, passenger side in similar location.)
Notice:
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints,
lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint
clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid
damage to parts and systems.
Important:
DRL jumper kit is to be installed on both the driver and passenger side headlamp wiring.
13.
Install one resistor to each mounting hole using bolt, washer, and nut provided in DRL jumper kit, P/N 15146012. The washer needs to go between
the resistor and the sheet metal surface to protect the resistor.
14.
Prior to installation of each nut, apply Loctite(R) Threadlocker 242, P/N 21485277 (in Canada, P/N 10953489), or equivalent (GM Material
Specification 998 5283) to exposed threads and tighten bolt.
