Control Modules — 1988 Chevrolet Corvette
Every control module on the 1984-1996 Chevrolet Corvette — where it lives, replacement time, and what it takes to program a replacement. Modules marked dealer / factory tool won't work after a part swap alone — budget for programming.
Heating Ventilation Air Conditioning Programmer (HVAC Programmer)4.5 hr R&Rrelearn only +0.3 hrautomatic climate control (standard)▸ programming details
📍 center of HVAC plenum, behind center console
🔧 Self-calibration procedure
⚠️ Electronic servo-driven blend door actuator. Must perform self-calibration after installation (ignition on, press OFF and WARM simultaneously). Notorious for gear failure requiring replacement.
Digital Instrument Panel (DIC)3.0 hr R&Rno coding
📍 instrument panel behind LCD/VFD display
⚠️ Fully digital LCD (1984-1989) or VFD vacuum fluorescent (1990-1996) display. Receives data from ECM via serial link. No programming required but may require odometer transfer per state law.
Electronic Brake Control Module / Bosch ABS Modulator (EBCM/BPMV)2.0 hr R&Rrelearn only +0.3 hrABS option (standard 1986+)▸ programming details
📍 driver side frame rail, forward of driver door
🔧 Scan tool or drive cycle
⚠️ Bosch ABS 2 system (1986-1987), Bosch ABS 2S (1988-1991), Bosch ABS 2U (1992-1996). Integrated pump/motor/valve body assembly. Bleeding procedure critical after replacement.
Radio / Entertainment System (Radio)1.5 hr R&Rrelearn only +0.1 hr▸ programming details
📍 center stack, integrated with climate control panel
🔧 Theft code entry
⚠️ Delco/Bose systems standard. Theft-lock feature requires 3-digit code entry after power loss (1990+). Code typically on card in owner's manual or retrievable from dealer.
⚠️ PROM chip contains all calibration data and must be transferred or replaced. 1986+ uses 8,192-baud ALDL. 1995 models may support early flash programming. LT1 and LT5 engines use different ECM hardware.
Selective Ride Control Module (SRC)1.0 hr R&Rno codingSelective Ride Control option (FX3, 1989-1996)
📍 rear storage compartment, driver side
⚠️ Controls Bilstein electronic dampers with Tour/Sport/Performance modes. Dash switch communicates with module. No programming required.
Low Tire Pressure Warning Module (LTPW)0.8 hr R&Rrelearn only +0.2 hrLow Tire Pressure Warning system (standard 1989-1996)▸ programming details
📍 rear storage compartment, passenger side
🔧 Magnet relearn procedure
⚠️ Monitors wheel speed sensor differences to infer low tire pressure. Relearn requires magnet held to sensor in each wheel well in sequence. Not a true TPMS with pressure sensors.
Vehicle Anti-Theft System Module (VATS)relearn only +0.5 hr▸ programming details
📍 integrated within ECM and ignition lock cylinder
🔧 Resistor pellet key and 3-minute relearn
⚠️ Pass-Key I system (1986-1988) or Pass-Key II (1989-1996). Resistor pellet in key must match ECM-stored value. Relearn requires 3-minute wait with key on after failed attempt. No separate module; logic in ECM.
