Details of time display
 CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-
tion switch OFF → ON again.
 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1
→ 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter
remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch
OFF → ON after returning to the normal condition if the malfunction is detected again.

TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

5. Remove hood opener on bottom left of instrument panel, and
then remove hood lock cable.
6. Remove grommet on lower dashboard, and pull out hood lock
cable from passenger room side.
CAUTION:
While pulling the cable, be careful not to damage (peel)
hood opener cable outer surface on edges of body through
hole.
INSTALLATION
Installation is in the reverse order of removal.
 Perform hood fitting adjustment. Refer to DLK-213, "
Fitting Adjustment".
Hood Lock Reinforcement
When installing hood lock reinforcement, loosen hood bolts, and
then tighten bolts in the order as shown.
Hood Lock Cable
1. Pull the hood lock cable through the panel hole to the engine compartment.
CAUTION:
Be careful not to bend the cable too much, keeping the
radius 100 mm (3.94 in) or more.
2. Check that the cable is not offset from the positioning grommet,
and push the grommet into the panel hole securely.
3. Apply the sealant around the grommet (at * mark).
4. Install cable securely to lock.
