GENERAL INFORMATION

WARNING
• To prevent damage to the ECU, never mix the black and gray connectors that attach to it. The black
connector is tethered to the ECU mounting plate to help avoid installing it in the gray port.
This section contains the information required to correctly troubleshoot the EFI gas vehicle. In addition to
troubleshooting, this section contains general information on the electrical system and the circuits of the electrical
system.

ACCESSORIES

For certain powered accessories, use the 9-pin connector located behind the instrument panel.

LOW OIL WARNING LIGHT

NOTE: When the key switch is placed in the ON position, the Low Oil Warning Light will illuminate for approximately 3
seconds as a bulb check function.
If the Low Oil Warning Light comes ON due to low oil level, and oil is added to correct the issue, the Low Oil
Warning Light will still remain ON. Cycle the key switch OFF and ON to reset the Low Oil Warning Light.
The gasoline vehicle is equipped with a low oil warning light (4), located at the top of the instrument panel. If the
warning light comes on, oil should be checked and added to the engine as necessary before continuing to use the
vehicle. See following CAUTION. The vehicle should never be driven when the low oil warning light remains on. If the
warning light goes on and off, the vehicle may be driven, but oil should be added at the first opportunity. The light will
flash repeatedly to indicate a possible problem with the electronic fuel injection (EFI) system. If the oil level is correct
and the warning light stays on, have a trained technician check the vehicle.
CAUTION
• Failure to add oil immediately when the low oil warning light stays on may result in permanent
engine damage.

GROUND LOCATIONS

Electrical grounds are located at the following areas:
• At the Battery: The starter/generator, voltage regulator, ECU, throttle position sensor and fuel pump module all
connect to the main wire harness and goes to the B– battery terminal.
• Between Engine and Battery: The engine and chassis each have a separate lead that connects to the main wire
harness and goes to the B– battery terminal.
