DESCRIPTION

SYMPTOM

Thermal cut-back due to high motor

temperature or high power bridge

temperature.

Traction system is operating at a reduced

performance level.

Probable Causes and Test Procedures

6.

Check the resistance through the main contactor coil. Refer to the section Electrical System 2200 SRM
1451 or Electrical System 2200 SRM 1287, Contactor Coil Check.
a. The resistance should measure approximately 22 ohms ±10%.

• Replace the coil.

7.

Check for shorts with truck frame.
a. Check resistance between the following points for greater than 1Mohm:

• CANH and truck frame
• CANL and truck frame
• B+ and truck frame
• B

and truck frame

• UT wire (traction motor) to truck frame
• VT wire (traction motor) to truck frame
• WT wire (traction motor) to truck frame
• PS2 wire (steer motor) to truck frame (if applicable)
• PM2 wire (pump motor) to truck frame
• PM1 wire (pump motor) to truck frame
