ENGINE BRAKE DISABLE

Engine Brake Disable is a digital input which is switched to battery ground whenever a vehicle
system such as a traction control device does not want engine braking to occur.
The CPC, which controls the Engine Brake directly, will not allow engine braking when the
input is switched to battery ground. DDEC VI supports the J1939 message to disable engine
brake (TSC1 command to source address 15).

Installation

The Engine Brake Disable Switch is wired to pin 4/18 on the CPC.

Programming Requirements and Flexibility

The options for this digital input are listed in Table 4-10.
