SUBJECT: Interior Fuse Box (F/B) “IG” and “ACC” Relay Under-Hood Fuse Box (M/B) Main Relay Replacement for Engine Will Not Crank / Start Condition

 

INTRODUCTION

If you receive a customer concern of a no crank / no start condition during very cold temperatures, the IG1, IG2, ACC1, ACC2 and/or the EGI Main relays may be the root cause and require replacement.  It is generally reported that the car starts normally after an overnight soak.  After the initial start, the customer drives a short distance then shuts the car off (example: at a gas pump or coffee shop).  After the time that it takes to pump their gas or get their coffee, they return to the car and it will not start.  The customer may also notice the instrument cluster and/or interior lights are not illuminating along with the HVAC being inoperative.  The source of this condition has been identified as condensation flash-freezing inside the relays. This bulletin provides a service procedure for replacement of all 5 relays, 4 of which are located together in the vehicle’s interior fuse box (F/B) and the EGI Main relay which is located in the under-hood Main fuse box (M/B).

SERVICE PROCEDURE

Fuse Box

 

*VERY IMPORTANT:  To prevent damage to the F/B itself or the relay connections inside it, the F/B MUST be removed from the vehicle and allowed to stabilize to a reasonable temperature PRIOR to relay removal.  DO NOT attempt to remove the relays with the F/B still installed in the vehicle.

  • Remove the 12mm nut and disconnect the negative cable from the battery temperature sensor.
  • Release the 3 push clips securing the under dash cover and push it up towards the pedals / bulkhead to get it out of the way.
  • Using a plastic trim tool, CAREFULLY remove the trim cover on the end of the instrument panel. Once removed, you will have access to the 1 Philips screw at the bottom, just above the hood release lever which secures the lower dash trim panel.
  • The remaining fasteners securing the lower dash trim panel are simply claws which will release easily. Once the trim panel is removed, unplug the harness connectors and put the panel aside.
  • There are three – 10mm hex fasteners securing the F/B to the dash structure; a bolt at the bottom and 2 nuts at the top on studs. Remove the 3 fasteners and start CAREFULLY unplugging harness connectors as you drop the F/B down, gaining more access as each harness connector is released.  There are 16 harness connectors plugged into the F/B.  Use a plastic trim tool to release the hinged yellow cover for the connector in the upper right corner (green arrow in photo below).

 

*IMPORTANT REMINDER:  To prevent damage to the F/B itself or relay connections inside it, the F/B MUST be removed from the vehicle and allowed to stabilize to reasonable temperature  PRIOR to relay removal.   DO NOT attempt to remove the relays with the F/B still installed in the vehicle.

  • Using a large pair of needle-nosed pliers, remove the 4 black relays by PULLING STRAIGHT UP on them in a motion perpendicular to the F/B as shown in the photos below. DO NOT WIGGLE THEM as damage to the relay connectors or the F/B itself may result.

4 black relays

 

  • Once ALL 4 of the black relays have been replaced, reinstall the F/B and re-assemble in the opposite order of removal.

NOTE: Always make sure all of the harness connectors are fully locked back in place (audible “click”) as each one is plugged back into the F/B.

IMPORTANT:  Relay identification:

The photos above show the IG1, IG2, ACC1 and ACC2 relays.  The EGI Main Relay photos are shown below.

  • Remove the under-hood M/B cover and CAREFULLY replace the EGI Main Relay indicated in the illustration below.

EGI Main RelayUnder-hood Main Fuse Box (M/B)

 

NOTE:  Make sure all of the harness connectors are fully locked back in place (audible “click”) as each one is plugged back into the F/B.

  • Reconnect the battery cable and torque the 12mm nut to 5.5 ft. lbs.
  • Start the car and verify all the combination meter warning lights cycle on / off normally.
  • For the power window Auto Up / Down feature to operate, the system will need to be re-initialized on BOTH front doors.
  • Confirm the HVAC and all electrical systems operate as designed to complete the repair.
