Nissan Maxima Service and Repair Manual: Turn signal lamp circuit

Nissan Maxima Service and Repair Manual / Driver controls / Exterior lighting system / DTC/circuit diagnosis / Turn signal lamp circuit

Description

The BCM monitors inputs from the combination switch to determine when to activate the turn signals. The BCM outputs voltage direction to the left and right turn signals during turn signal operation or both during hazard warning operation. The BCM sends a turn signal indicator request to the combination meter via the CAN communication lines.

The BCM performs the fast flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is open.

NOTE: Turn signal lamp blinks at normal speed when using the hazard warning lamp.

Component Function Check

1.CHECK TURN SIGNAL LAMP

CONSULT

  1. Select "FLASHER" of BCM (FLASHER) active test item.
  2. While operating the test item, check that the turn signal lamp blinks.

LH : Turn signal lamp LH blinking
RH : Turn signal lamp RH blinking
OFF : The turn signal lamp OFF

Diagnosis Procedure

1.CHECK TURN SIGNAL LAMP BULB

Check the applicable lamp bulb to be sure the proper bulb standard is in use and the bulb is not open.

2.CHECK TURN SIGNAL LAMP OUTPUT VOLTAGE

  1. Turn the ignition switch OFF.
  2. Disconnect front combination lamp connector, door mirror connector (if equipped with turn signal in mirror) and rear combination lamp connector.
  3. Turn the ignition switch ON.
  4. With turn signal switch operating, check the voltage between the front combination lamp harness connector and ground.
  5. With turn signal switch operating, check the voltage between the rear combination lamp harness connector and ground.
  6. With turn signal switch operating, check the voltage between the door mirror (if equipped with turn signals in the mirrors) harness connector and ground.
