2006 INFINITI M35 Color wire

EC-540
[VQ35DE]
DTC P1550 BATTERY CURRENT SENSOR
Revision: 2006 January2006 M35/M45
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
*: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to SC-5, "SPECIFIC GRAVITY CHECK" .
Diagnostic ProcedureNBS0053W
1. CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Loosen and retighten two ground screws on the body.
Refer to EC-172, "
Ground Inspection" .
OK or NG
OK >> GO TO 2.
NG >> Repair or replace ground connections.
