battery location NISSAN X-TRAIL 2001 Service Repair Manual

GI-10
HOW TO USE THIS MANUAL
1.Before performing trouble diagnoses, read the “Preliminary Check”, the “Symptom Chart” or the
“Work Flow”.
2.After repairs, re-check that the problem has been completely eliminated.
3.Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.
4.Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a
sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG
section for identification of harness connectors.
5.When checking circuit continuity, ignition switch should be OFF.
6.Before checking voltage at connectors, check battery voltage.
7.After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
that all harness connectors are reconnected as they were.
HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES
1.Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in enclosed test groups.
2.Questions and required results
Questions and required results are indicated in bold type in test group.
The meaning of are as follows:
3.Symbol used in illustration

Num-
berItem Description
1 Power condition
●This shows the condition when the system receives battery positive voltage (can be oper-
ated).
2 Fusible link
●The double line shows that this is a fusible link.
●The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tion
●This shows the location of the fusible link or fuse in the fusible link or fuse box. For arrange-
ment, refer to PG section, POWER SUPPLY ROUTING.
4Fuse
●The single line shows that this is a fuse.
●The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating
●This shows the current rating of the fusible link or fuse.
6 Connectors
●This shows that connector E3 is female and connector M1 is male.
●The G/R wire is located in the 1A terminal of both connectors.
●Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ connec-
tor. Refer to PG section, SMJ (SUPER MULTIPLE JUNCTION).
7 Optional splice
●The open circle shows that the splice is optional depending on vehicle application.
8 Splice
●The shaded circle shows that the splice is always on the vehicle.
9 Page crossing
●This arrow shows that the circuit continues to an adjacent page.
●The A will match with the A on the preceding or next page.
10 Common connector
●The dotted lines between terminals show that these terminals are part of the same connector.
11 Option abbreviation
●This shows that the circuit is optional depending on vehicle application.
12 Relay
●This shows an internal representation of the relay. For details, refer to PG section, STAN-
DARDIZED RELAY.
13 Connectors
●This shows that the connector is connected to the body or a terminal with bolt or nut.

On Board Diagnosis LogicEBS00M1N
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation ProcedureEBS00M1O
CAUTION:
Always drive at a safe speed.
NOTE:
●If DTC P0011 is displayed with DTC P1111, first perform trouble diagnosis for “DTC P1111”. See
EC-271
.
●If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and
wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10V and 16V at
idle.
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Maintain the following conditions for at least 20 consecutive sec-
onds.
