Description
The terminal “l” circuit controls the charge warning lamp. The charge warning lamp turns on when the ignition switch is set to on or start. When the generator is providing sufficient voltage with the engine running, the charge warning lamp turns off. If the charge warning lamp illuminates with the engine running, a malfunction is indicated.
Diagnosis Procedure
Regarding wiring diagram information, refer to chg-9, "wiring diagram".
1.Check “l” terminal circuit (short)
Does charge warning lamp illuminate? YES >> GO TO 2.
NO >> Refer to CHG-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or CHG-17, "Work Flow (Without EXP-800 NI or GR8-1200 NI)".
2.Check harness continuity (short circuit)

Is the inspection result normal? Yes >> replace the combination meter. Refer to mwi-77, "removal and installation".
No >> repair or replace the harness or connectors.

Diagnosis procedure
1.Check connector
Turn the ignition switch OFF.
Disconnect the battery cable from the negative terminal.
Check the terminals and connectors of the ECM for damage, bend and loose

Measurement of weights
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the vehicle is loaded, drive
to a scale and weigh the front and the rear
wheels separately to determine axle
loads. Individual axle loads should not exceed
either of the gross axle weight ratings
