Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
NOTE:
If no fault code is displayed in B.U.D.S., the E-RAVE
actuator can still be faulty. It could be a mechanical
problem.
If actuator overheating occurs, fault code P0078 will
appear. It could be caused by mechanical problems
such as overtighten cables or damaged pulleys.
If a communication problem occurs between ECM
and actuator, fault code P0600 will appear. It could
also be caused by a not-powered actuator.
Voltage Test
Remove the headlight relay (R2).
NOTE: To prevent battery discharge, headlight
fuse (F8) can be removed.
Bypass relay with a jumper.

1. Jumper
2. Headlight fuse
Disconnect the E-RAVE actuator connector.
Measure voltage between terminal 1 (on harness
side) and battery ground.
If battery voltage is read, check continuity be-
tween terminal 2 (on harness side) and battery
ground.
If continuity is faulty, repair/replace
wiring/connector.
If battery voltage is not read, check the cor-
responding fuse(s), relay and continuity of cir-
cuit V V-1. If continuity is faulty, repair wiring/
connector.
Communication Test
A not-working actuator can be caused by a com-
munication problem between ECM and E-RAVE
actuator.
If no power goes to the E-RAVE actuator, no com-
munication can take place.
If B.U.D.S. works, it validates the ECM works and
can communicate. Therefore the problem is in the
wires going to the E-RAVE actuator.
Check continuity of wires V V-3 and V V-5. If con-
tinuity is faulty, repair wiring/connector.
If continuity is good, try a new actuator.
Dynamic Test, Replacement and
Cable Adjustment
Refer to RAVE system.
DOUBLE IGNITION COIL
A35C3RB

1. Ignition coil
NOTE: The ECM energizes the primary side of
each ignition coil individually. It can detect if the
double ignition coil is connected otherwise a trou-
ble code will appear upon starting.
Using the vehicle communication kit (VCK) with
the B.U.D.S. software, energize the ignition coil
from the
Activation section.
You should hear the spark occurring. In doubt, use
an inductive spark tester or a sealed tester – avail-
able from after-market tool/equipment suppliers –
to prevent spark occurring in the engine compart-
ment. Otherwise, perform the following checks.
An ignition coil with good resistance measure-
ment can still be faulty. Voltage leak can occur
at high voltage level which is not detectable with
an ohmmeter. Replacing the ignition coil may be
necessary as a test.
