2007 NISSAN LATIO warning light

PG-22
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: June 20062007 Versa
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following six steps are repeated three times.
(A): Oil pressure warning lamp is blinking when the auto active test is operating.
Concept of Auto Active Test

IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.

DIAGNOSTIC PROCEDURE 1
Check Charge Warning Lamp Circuit
1. CHECK CHARGE WARNING LAMP CIRCUIT CONNECTION
Check to see if terminal 2 is clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair terminal 2 connection. Confirm repair by performing complete Battery/Starting/Charging
system test.
2. CHECK CHARGE WARNING LAMP CIRCUIT
1. Disconnect generator connector F1.
2. Apply ground to generator connector F1 terminal 2 with the igni-
tion switch in the ON position.
OK or NG
OK >> GO TO SC-28, "WORK FLOW" .
NG >> Check the following.

10A fuse [No. 3, located in fuse block (J/B)]

CHARGE lamp

Harness for open or short between combination
meter and fuse

Harness for open or short between combination meter and generator CHARGE lamp should light up.

Trouble Diagnosis Without CONSULT-IIEHS001V5
DIAGNOSTIC PROCEDURE 6
Inspect SRS Malfunction Using "AIR BAG" Warning Lamp—Diagnosis Mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is detected in User mode.
1. Turn ignition switch ON.
2. After “AIR BAG” warning lamp lights for 7 seconds, turn ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two times.
5. Turn ignition switch ON.
SRS is now in Diagnosis mode.
"AIR BAG" warning lamp operates in Diagnosis mode according to the Warning Lamp Flash Code Chart:
