DEFINITIONS AND ABBREVIATIONS
Allison Transmission Electronic Control System — The complete electronic control system for the transmission, including all detail components.
Bi-Directional Communication Link (BDCL) — Hard wire connections which allow the Allison Electronic
Control system to communicate with other engine or transmission controls.
Check Transmission Light — Optional instrument panel warning light that alerts the operator that a problem has occurred and the vehicle should be serviced as soon as possible. Also used by the technician to read diagnostic codes when a diagnostic data reader is not used.
Detroit Diesel Electronic Controls (DDEC) — Detroit Diesel’s electronic engine control system.
Diagnostic Codes (Trouble Codes) — Two-digit codes stored in the electronic control ECU memory. These codes are set when system self-diagnostics detects problems. Technicians access codes and use them to help troubleshoot problems.
Diagnostic Data Link (DDL) — Cab harness connector which allows a diagnostic data reader to interface with the Allison Electronic Control system.
Digital Display Unit (DDU) — Optional electronic component that displays various system operating and warning information.
Digital Volt Ohmmeter (DVOM) — Electrical device used for performing voltage, continuity and resistance tests.
Do Not Shift Light — Warning lamp located on the shift selector. This indicator alerts the driver that a potentially serious problem has been detected and shift selection has been limited.
Electronic Control Inquiry System (ECIS) — On-line data base (available through Distributor Parts Departments) that indicates which options are programmed on a particular PROM.
Electronic Control Unit (ECU) — The Allison Electronic Control system onboard microcomputer. This is the electronic “brain” for the system.
Fluidic Oil Level Sensor (FOLS) — One of the three types of switches that signal the ECU when a low lube pressure or low oil level condition exists. The FOLS uses a separate housing that bolts to the bottom of the valve body. It is very similar to the Low Oil Pressure/Level Sensor, but does not use a bi-metal strip.
Infinity (∞) — An indication that circuit or component resistance is so high it can not be measured. Generally, this means continuity is not present (the circuit is open).
Jumper Wire — A short piece of wire used to connect two electrical circuits or bypass a portion of a circuit.
Low Oil Level/Pressure Sensor — One of the three types of switches that signal the ECU when a low lube pressure or low oil level condition exists. The Low Oil Level/Pressure Sensor uses a separate housing that bolts to the bottom of the valve body. It is very similar to the Fluidic Oil Level Sensor and uses a bi-metal strip to compensate for cold oil temperatures until the transmission warms up.
Lube Pressure Switch — One of the three types of switches that signal the ECU when a low lube pressure or low oil level condition exists. The Lube Pressure Switch is configured like the forward and reverse pressure switches. It plumbs directly into the lubrication oil passage.
Ohm (Ω) — A unit of electrical resistance measurement.
Options — Programmed special features. Examples — Bed Hoist Interlock, Loading Hold, Neutral-To-Range
Inhibit, etc. Options must be programmed in the PROM and properly wired.
Programmable Read Only Memory (PROM) — This is the microchip that contains all the transmission shift and control information. The PROM is located in the ECU.
Power Take-Off (PTO) — Transmission-mounted accessory drive unit. PTOs are used to operate pumps and other accessories on specialty vehicles.
Self-Diagnostics — The Allison Transmission Electronic Control’s built-in capability to recognize system problems.
Solenoid — Components in the electro-hydraulic valve body that act as switches to direct hydraulic pressure into specific passages or to exhaust.
Speed Sensor (Output Speed Sensor) — Provides the electronic control system with output speed information.
The speed sensor replaces the conventional hydraulic governor system.
Splice — A connection of two or more wires. When repairing harness wires, they are spliced using special butt connectors.
Temperature Sensor — Monitors sump oil temperature for the ECU. On-highway sensors are mounted on the solenoid control circuit (on the internal wiring harness). Off-highway sensors are mounted in the lock-up valve body.
Throttle Position Sensor (TPS) — Provides the electronic control system with throttle position information. The TPS replaces the conventional hydraulic modulator system.
Transmission Engine Communication Link (TECL) — A type of Bi-Directional Communication Link
(BDCL) that allows the Allison Transmission Electronic Control to communicate with engine controls.
Transmission Test Switch — Vehicle manufacturer-installed switch that places the electronic control system in its diagnostic mode. When the switch is on, trouble codes can be retrieved.
Transmission to Transmission Communication Link (TTCL) — A type of Bi-Directional Communication
Link (BDCL) that allows the Allison Transmission Electronic Control to communicate with other
transmission controls.
Vehicle Interface — Term describing the electrical connections between the vehicle and the Allison
Transmission Electronic Control system.
