Test Item
Description
RETAINED PWR
This test is able to supply RAP signal (power) from smart entrance control unit to power window
system, power sunroof system. Those systems can be operated when turning on “RETAINED
PWR” on CONSULT-II screen even if the ignition switch is tuned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch “OFF” position.
“RETAINED PWR” should be turned “ON” or “OFF” on CONSULT-II screen when ignition
switch is ON. Then turn ignition switch OFF for checking retained power operation. CON-
SULT-II might be stuck if “RETAINED PWR” is turned “ON” or “OFF” on CONSULT-II
screen when ignition switch is OFF.
Trouble Diagnoses
NHEL0258
WARNING:
I
The xenon headlamp has a high-tension current generating area. Be extremely careful when remov-
ing and installing. Be certain to disconnect the battery negative cable prior to removing or install-
ing.
I
When the xenon headlamp is lit, do not touch the harness (covered with red or amber insulation),
bulb itself or the bulb socket with your bare hands.
I
Never service a xenon headlamp with wet hands.
I
When checking body side harness with a circuit tester, be certain to disconnect the harness con-
nector from the xenon headlamp.
I
When the xenon headlamp is lit, the xenon bulb must be installed in the headlamp housing. (Never
turn on xenon headlamp, if the bulb is out of the headlamp housing.)
CAUTION:
Make sure to install the bulb securely; if the xenon bulb is improperly installed in its socket, high-ten-
sion current leaks occur. This may lead to a melted bulb and/or bulb socket.
Symptom
Possible cause
Repair order
Neither headlamp operates.
1. 10A fuse
2. Lighting switch
3. Smart entrance control unit
1. Check 10A fuse [No. 13, located in fuse block (J/B)].
Verify battery positive voltage is present at terminal
49 of smart entrance control unit.
2. Check Lighting switch.
3. Check smart entrance control unit. (EL-406)

2. Headlamp LH relay
3. Headlamp LH relay circuit
4. Lighting switch circuit
5. Smart entrance control unit
1. Check 20A fuse (No. 54, located in fusible link and
fuse box). Verify battery positive voltage is present
at terminals 1 and 6 of headlamp LH relay.
2. Check headlamp LH relay.
3. Check harness between headlamp LH relay and
smart entrance control unit.
4. Check harness between smart entrance control unit
and lighting switch.
5. Check smart entrance control unit. (EL-406)
