Vehicle Check/Preparation

VEHICLE CHECK/PREPARATION

Before using the diagnostic tool to carry out any test, refer to the Important Safety Notice and the necessary visual checks listed below.

Visual Checks

WARNING: This vehicle is equipped with high voltage cables, components, and wiring. The high voltage warning labels containing the high voltage symbol are located on each high voltage component. High voltage cables, and wiring are orange in color. Certified rubber insulating gloves and a face shield must be worn when working with the high voltage cables, components, or wiring. The ignition key must be cycled to the OFF position for a minimum of 5 minutes, and the high voltage traction battery service disconnect plug placed in the servicing/shipping position before disconnecting the high voltage cables. Failure to follow these instructions may result in personal injury or death.

Do not disconnect, disable, or touch the high voltage cables, components, or wiring during the module reprogramming procedure because high voltage is present. The high voltage warning labels containing the high voltage symbol are located on each high voltage component. High voltage cables, and wiring are orange in color. Failure to follow these instructions may result in personal injury or death.

- Inspect the air cleaner and inlet duct.
- Check all engine vacuum hoses for damage, leaks, cracks, kinks and proper routing.
- Check the powertrain control module (PCM) or transaxle control module (TCM) wiring harness for proper connections, bent or broken pins, corrosion, loose wires and proper routing.
- Examine all high voltage cables and connectors for secure connection, damaged, burned or overheated insulation and loose or broken condition.
- Verify the traction battery high voltage service plug is properly connected.
- Verify the front and rear inertia fuel shutoff (IFS) switches are not tripped.
- Check the powertrain control module (PCM), sensors, and actuators for physical damage.
- Check the engine coolant for proper level and mixture.
- Check the motor electronics coolant for proper level and mixture.
- Check the transaxle fluid level and quality. Refer to Automatic Transmission/Transaxle.
- Make all necessary repairs before continuing with the quick test.

Vehicle Preparation
- Carry out all safety steps required to start and run vehicle tests. Apply the parking brake, place the gear selector firmly into the PARK position and block the drive wheels.
- Verify the high voltage traction battery state of charge is equal to or greater than 45% by monitoring the traction battery control module (TBCM) state of charge PID. If the monitored PID displays the state of charge below 45%, start and idle the engine with full A/C ON.
- Turn the A/C on and verify it functions correctly.
- Turn off all electrical loads, such as radios, lamps, A/C, blower, and fans.
- Start the engine and bring it up to the normal operating temperature before running the quick test.
