NOTE: Always disconnect the negative side first. Disconnect the positive cable (B) from the battery. Wait at least 3 minutes before starting work.
  2. Driver's Dashboard Undercover Turn the lock knob (A) 90 °, then gently pull down the front edge of the driver's dashboard undercover (B) to detach the clip (C). Pull away the undercover to release the pin (D) from the holder (E), then remove the driver's dashboard undercover.
  3. Driver's Dashboard Panel Assembly Carefully pry out the driver's dashboard panel assembly (A) with the appropriate trim tool to detach the clips (B). Disconnect the connector (C), then remove the driver's dashboard panel assembly.
  4. Driver's Dashboard Lower Cover Carefully pry out the driver's dashboard lower cover (A) with the appropriate trim tool to detach the clips (B). Disconnect the connector (C), then remove the driver's dashboard lower cover.
  5. Under-Dash Fuse/Relay Box Disconnect the connectors from the fuse side of the under-dash fuse/relay box (A). Detach the under-dash fuse/relay box. Disconnect the connectors from the back side of the under-dash fuse/relay box, then remove the under-dash fuse/relay box. Carefully remove the relays using a relay puller. NOTE: Do not use pliers. Pliers will damage the relays, which could cause the engine to stall or not start or cause other functions to fail.
  6. Under-Dash Fuse/Relay Box - Canada models Disconnect the connectors from the fuse side of the under-dash fuse/relay box (A). Remove the covers (B) from the under-dash fuse/relay box. Detach the under-dash fuse/relay box. Disconnect the connectors from the back side of the under-dash fuse/relay box, then remove the under-dash fuse/relay box. Carefully remove the relays using a relay puller. NOTE: Do not use pliers. Pliers will damage the relays, which could cause the engine to stall or not start or cause other functions to fail.

  1. Under-Dash Fuse/Relay Box - Canada models NOTE: The imoes unit is built into the MICU, which is part of the under-dash fuse/relay box. Because of this construction, the imoes must be registered, or the vehicle will not start. Install the relays in the under-dash fuse/relay box (A). Connect the connectors to the back side of the under-dash fuse/relay box. Install the under-dash fuse/relay box. Install the covers (B) to the under-dash fuse/relay box. Connect the connectors to the fuse side of the under-dash fuse/relay box.
  2. Under-Dash Fuse/Relay Box NOTE: The imoes unit is built into the MICU, which is part of the under-dash fuse/relay box. Because of this construction, the imoes must be registered, or the vehicle will not start. Install the relays in the under-dash fuse/relay box (A).
