Nissan Qashqai (2007-2010). Manual — part 1860

CHG-12

< COMPONENT DIAGNOSIS >

L TERMINAL CIRCUIT (OPEN)

4.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check continuity between combination meter harness connector M34 terminal 2 and 10A fuse [No.4, located
in the fuse block(J/B)].

Does continuity exist?

YES

>> GO TO 5.

NO

>> Repair the harness.

5.

CHECK POWER SUPPLY CIRCUIT

1.

Connect the battery cable to the negative terminal.

2.

Check voltage between combination meter harness connector and ground.

Is the inspection result normal?

YES

>> Replace combination meter.

NO

>> Inspect the power supply circuit. Refer to

PG-47, "Wiring Diagram - IGNITION POWER SUPPLY -

"

L TERMINAL CIRCUIT (SHORT)

Description

INFOID:0000000000955247

The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the igni-
tion switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running,
the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunc-
tion is indicated.

Diagnosis Procedure

INFOID:0000000000955248

1.

CHECK “L” TERMINAL CIRCUIT (SHORT)

1.

Turn ignition switch OFF.

2.

Disconnect alternator harness connector.

3.

Turn ignition switch ON.

Does charge warning lamp illuminate?

YES

>> GO TO 2.

NO

>> Refer to

CHG-3, "K9K MODELS : Work Flow"

(K9K models) or

CHG-4, "HR16DE/MR20DE MOD-

ELS : Work Flow"

(HR16DE/MR20DE models).

2.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Disconnect combination meter connector.

4.

Check continuity between combination meter harness connector and ground.

Is the inspection result normal?

YES

>> Replace combination meter.

NO

>> Repair the harness.

S TERMINAL CIRCUIT

S TERMINAL CIRCUIT

Description

INFOID:0000000000955249

The output voltage of the alternator is controlled by the IC regulator at the “S” terminal detecting the input volt-
age.
The “S” terminal circuit detects the battery voltage to adjust the alternator output voltage with the IC regulator.

Diagnosis Procedure

INFOID:0000000000955250

1.

CHECK “S” TERMINAL CONNECTION

1.

Turn ignition switch OFF.

2.

Check if “S” terminal is clean and tight.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair “S” terminal connection.

2.

CHECK “S” TERMINAL CIRCUIT

Check voltage between alternator harness connector and ground.

Is the inspection result normal?

YES

>> Refer to

CHG-4, "HR16DE/MR20DE MODELS : Work Flow"

.

NO

>> Check harness for open between alternator and fuse.
