TL960 SERVICE MANUAL
To make up a "breakout" T harness:
Join three 12" 10 AWG wires in the center of each with a 6" 20 AWG wire, making sure of 100% bond.
Place male Deutch connector #DT 04-3P-E004 on one end of the three 12" wires.
Place a female Deutch connector on the opposite end and on the 6" lead.
Using Caterpillar crimping tool, #1U5804, crimp the terminals onto each wire. See Figure 1.
There may be times when it is more expedient to install a new sensor or a new ECM in a process of elimination, which means it would be wise to have one of each in stock.
Troubleshooting the Throttle Position Sensor System
Considerable training is required of the service technicians, and investment must be made in some new sophisticated test equipment, as well as, having on hand the appropriate service and troubleshooting manuals from Caterpillar. The most critical manual is Caterpillar Electronic Troubleshooting #7AS1-UP, available from your area Caterpillar dealer. This manual goes through a step-by-step sequence in checking any given fault code that appears on the dash light.
