Nissan Sentra Service Manual / Electrical & power control / Charging system / Dtc/circuit diagnosis / L terminal circuit (open)

Description

The “L” terminal circuit controls the charge warning lamp. The charge warning lamp turns ON when the ignition switch is set to ON or START. When the generator is providing sufficient voltage with the engine running, the charge warning lamp turns OFF. If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

Diagnosis procedure

Regarding Wiring Diagram information. Refer to CHG-9, "Wiring Diagram".Рњ

1.Check “l” terminal connection

  1. Turn ignition switch off.
  2. Check if “l” terminal is clean and tight.

Is the inspection result normal? Yes >> go to 2.

No >> repair “l” terminal connection. Confirm repair by performing complete charging system test using exp-800 ni or gr8-1200 ni (if available). Refer to applicable instruction manual for proper testing procedures.

2.Check “l” terminal circuit (open)

  1. Disconnect the generator connector.
  2. Apply ground to generator harness connector terminal.
  3. Check condition of the charge warning lamp with the ignition switch in the on position.

Does it illuminate?


Does it illuminate? YES >> “L” terminal circuit is normal. Refer to CHG-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or CHG-17, "Work Flow (Without EXP-800 NI or GR8-1200 NI)".

NO >> GO TO 3.

3.Check harness continuity (open circuit)

  1. Disconnect the battery cable from the negative terminal.
  2. Disconnect the combination meter connector.
  3. Check continuity between generator harness connector and combination meter harness connector.

Is the inspection result normal?


Is the inspection result normal? Yes >> go to 4.

No >> repair or replace the harness or connectors.

4.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?


Is the inspection result normal? Yes >> replace the combination meter. Refer to mwi-77, "removal and installation".

No >> repair or replace the harness or connectors.
