However, the code will remain in history until cleared. The CCM will not display “SYS” if the problem is repaired. If the problem causing the code is fixed, the code must be cleared. The code set and was not cleared after repairs were done. This may have been caused from someone driving the car with the radio out for service. All other codes will be displayed.Įxample: H72 code.
#1994 FORD ENGINE CODES DIGITAL ODOMETER MANUAL#
With LT5 engines, the automatic or manual sequence will not display the ECM codes. If any codes are missed, turn the ignition off and then back to the on position to restart the code display. Once all module codes are displayed, “-” displays, ending the sequence.
The codes themselves will be displayed in place of the speedo readout with a prefix: H for History or C for Current, followed by the code. Module numbers 1, 4 or 9 will display directly below the speedo readout area. 1990-1991 Corvette CCMs will not display any ABS/ASR or EBTCM codes. Module 1 CCM (central control module) is first, followed by module 4 ECM (engine control module) and finishing with module 9 ABS/ASR EBTCM (anti-lock brake system/acceleration slip regulation/electronic brake traction control module) codes. The CCM will display all module codes (sequentially) in the speedometer read-out area.

The ALDL connector is located above your right knee when seated in the driver seat. Place the other end of your jumper wire in the position directly below number 4.
#1994 FORD ENGINE CODES DIGITAL ODOMETER INSTALL#
Install one end of the the jumper wire 4 positions from the upper right. The ALDL numerals start with 1 in the upper left hand position and 9 in the lower left position. GM used numerals in place of alphas on all 1994 and up Corvettes at the ALDL. Position A is in the top right corner position G is the first position at the lower left of the ALDL.ġ994-1996 Corvette ECM, CCM and ASR/EBTCM codes are accessed placing the jumper wire in ALDL connector positions 4 and 12. There is no way to damage any component during the interrogation procedures just turn the ignition key off and start over.ġ990-1993 Corvette ECM and CCM codes can be accessed placing a jumper wire in ALDL positions A and G. There is no real concern if you are careful during the installation of the jumper wire. Our 1994-1996 ALDL has the jumper wire in place ready for CCM interrogation.ġ994-1996 Corvettes with the later designated OBDII (On-board Diagnostics) connector use battery voltage for scanner power, so it also has the potential for possible circuit damage. This connector position can harm other ALDL circuits if battery voltage is inadvertently jumped to a control circuit. It houses a fuel pump override lead that has battery voltage. Any loose strands could short another terminal.ġ990-1993 Corvettes use the first generation ALDL connector. Watch that the twisted wires stay inside the terminal during installation. This 1990-1993 ALDL has the jumper in place. The jumper wire is placed in the proper connector slots and the interrogation begins. The ALDL (Assembly Line Diagnostic Link) is used to access the codes with a jumper wire. For example, the CCM interaction is invaluable when diagnosing interior component or courtesy light problems and the VATS (Vehicle Anti-theft System). Although limited ECM data is available, it can point you in the right direction. In addition, ABS/ASR (Anti-lock Brake System/Acceleration Slip Regulation) and EBTCM (Electronic Brake Traction Control Module) trouble codes and data were introduced on the 1992-1996 Corvettes. When the 1990 Corvette debuted, GM introduced ECM (Engine Control Module) and CCM (Central Control Module) trouble codes. Have you noticed “SYS” intermittently showing up in your 1990-1996 Corvette’s speedometer display? This means there is a trouble code stored in one of the on-board control modules.
