DescriptionINFOID:0000000001724511
The terminal “2” (L) circuit controls the charge warning lamp. The charge warning lamp illuminates when the
ignition switch is set to ON or START. When the generator is providing sufficient voltage with the engine run-
ning, the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a
malfunction is indicated.
Diagnosis ProcedureINFOID:0000000001724512
1.CHECK CHARGE WARNING LAMP CIRCUIT CONNECTION
Verify generator connector F1 terminal 2 is clean and tight.
Is the connection secure?
YES >> GO TO 2
NO >> Repair the connection. Confirm repair by performing complete Starting/Charging system test.
Refer to Technical Service Bulletin.
2.CHECK CHARGE WARNING LAMP CIRCUIT
1. Disconnect generator connector F1.
2. Apply ground to generator harness connector F1 terminal 2 with
the ignition switch in the ON position.
Does the charge lamp illuminate?
YES >> Check generator function. Refer to CHG-33, "Work
Flow".
NO >> GO TO 3
3.CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect the generator connector F1 and combination meter
connector M24.
3. Check continuity between generator harness connector F1 ter-
minal 2 and combination meter harness connector M24 terminal
38.
4. Check continuity between generator harness connector F1 ter-
minal 2 and ground.
Are the continuity results as specified?
YES >> Replace the combination meter. Refer to XX-XX, "*****".
NO >> Repair the harness or connector.Charge lamp should illuminate

FUEL PUMP
FUEL PUMP
DescriptionINFOID:0000000001671103
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine
startability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows
that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when
the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging,
thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump
relay, which in turn controls the fuel pump.
