B TERMINAL CIRCUIT STR-13 < COMPONENT DIAGNOSIS > C D E F G H I J K L M A STR N P O COMPONENT DIAGNOSIS B TERMINAL CIRCUIT Description INFOID:0000000005276063 Terminal "2" (B) is constantly supplied with battery power. Diagnosis Procedure INFOID:0000000005276064 Regarding Wiring Diagram information, refer to STR-18, "Wiring Diagram - VQ40DE - With Clutch Interlock STR-24, "Wiring Diagram - VQ40DE - Without Clutch Interlock Cancel Switch" . CAUTION: Perform diagnosis under the condition that the engine cannot start by the following procedure. Remove fuel pump fuse. 2. Crank or start the engine (where possible) until the fuel pressure is depleted. 1. CHECK TERMINAL 2 POWER SUPPLY VOLTAGE 1. Turn ignition switch OFF. 2. Make sure that starter motor connector E210 terminal 2 connection is clean and tight. 3. Check voltage between starter motor connector E210 terminal 2 Is there battery voltage present? YES >> GO TO 2 NO >> Check harness between battery and starter motor for open circuit. 2. CHECK BATTERY CABLE (VOLTAGE DROP TEST) 1. Shift the transmission into park or neutral. 2. Check voltage between battery positive terminal and starter Is the voltage drop less than 0.2V? YES >> GO TO 3 NO >> Check harness between the battery and the starter motor for high resistance. 3. CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST) (+) (-) Voltage Connector Terminal E210 2 Ground Battery voltage AWBIA0122GB (-) (+) Condition Voltage Connector Terminal E210 2 Battery (+) terminal While cranking the engine Less than 0.2V AWBIA0123GB |
