STARTING SYSTEM
Revision: 2006 November2007 350Z
DIAGNOSTIC PROCEDURE 1
Check “B” Terminal Circuit
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
1. CHECK “B” TERMINAL CIRCUIT
1. Turn ignition switch OFF.
2. Make sure that starter motor “B” terminal connection is clean
and tight.
3. Check voltage between starter motor “B” terminal and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between battery and starter motor for open circuit.
2. CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)
1. Shift A/T selector lever to “P” or “N” position. (A/T models)
Keep depressing clutch pedal fully. (M/T models)
2. Check voltage between starter motor “B” terminal and battery
positive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter motor for poor continuity.
*1 For battery testing, use Battery Ser-
vice Center (J-48087). For details
