LESSON 4: SPECIAL SERVICE TOOLS AND PROCEDURES

4-9

•

Oil Pressure Switch Operation – The Electric Motor/Transaxle Test

Box interfaces directly with the oil pressure switch. By manually

turning on and off the oil pump, the Electric Motor/Transaxle Test

Box turns a light on and off respectively.

•

Oil Pump Operation – In addition to monitoring the oil pressure

switch, the Electric Motor/Transaxle Test Box also provides

information on oil pump operation. A manual switch to turn the oil

pump on and off is provided on the front of the tester along with an

interface for a digital voltmeter. This interface will provide the

technician with a voltage that is directly proportional to the current

flowing to the oil pump. This current will be checked to verify that

it is within a specified range for proper operation.

Equipment Hookup

•

The Electric Motor/Transaxle Test Box connects to both the

transaxle connections and the cigar lighter socket.

– 9-Pin Transaxle Connector – Located on the top of the motor

assembly in front of the three power leads.

– Oil Pressure Switch Connector – Located on the lower rear of

the gear cover.

– Oil Pump Bulkhead Connector – On the gear cover in front of

the driver side halfshaft.

•

The Capacitor Discharge Tool is used to ensure that capacitors

have discharged prior to performing vehicle service.

•

Connects to a Digital Volt-Ohmmeter (DVOM) to determine when

the voltage has completely discharged.

8-Volt Battery Charger

•

It is used to charge the 8-volt battery modules of the traction
