Externally Controlled

Wiring Diagram:

BRAKE

The BRAKE telltale is directly controlled by switches in the vehicle. Power for the telltale is pulled from the IPC Ignition 1 input (pin 'C13' CKT 39). Refer to DIAGRAMS for diagnosis.

SERVICE ENGINE SOON

The SERVICE ENGINE SOON telltale is directly controlled by the engine control module (PCM). Power for the telltale is pulled from the IPC Ignition 1 input (pin 'C13', CKT 39). Refer to COMPUTERS AND CONTROL SYSTEMS for diagnosis. Computers and Control Systems

ANTI-LOCK BRAKE

The ANTI-LOCK BRAKE telltale is directly controlled by the Antilock Brake System (ABS) module. Power for the telltale is pulled from the IPC Ignition 1 input (pin 'C13', CKT 39). Refer to BRAKES AND TRACTION CONTROL for diagnosis. Brakes and Traction Control

INFLATABLE RESTRAINT

The INFLATABLE RESTRAINT telltale is directly controlled by the Diagnostic Energy Reserve Module (DERM). Power for the telltale is pulled from the IPC Ignition 1 input (pin 'Cl 3', CKT 39). Refer to Supplemental Inflatable Restraint (SIR) SYSTEM for diagnosis. Air Bag Systems

SECURITY

The SECURITY telltale is directly controlled by the Universal Theft Deterrent and Pass-Key modules. Power for the telltale is pulled from the IPC Battery input (pin 'C12', CKT 812). Refer to ANTITHEFT AND ALARM SYSTEMS for diagnosis. Antitheft and Alarm Systems

SAFETY BELT

The SAFETY BELT telltale is directly controlled by the Chime module. Power for the telltale is supplied by the Chime module at IPC pin 'A3' (CKT 237). The telltale is always grounded by the IPC single point ground (pin A5', CKT 804). Refer to AUDIBLE WARNINGS for diagnosis. Instrument Panel, Gauges and Warning Indicators

CRUISE ENGAGED - (Digital Only)

The CRUISE ENGAGED telltale is a vacuum fluorescent display controlled by the IPC. The telltale is illuminated at any time that the PCM indicates (via serial data to the IPC) that the cruise control system in engaged.
