Retrieving Problem Codes

NOTE: The 4WS control unit may store 10 codes each in its main and secondary CPUs. Codes from the main CPU will be displayed first, followed by a 1.6 second pause and 3 seconds of rapid blinking. The codes stored in the secondary CPU will then be displayed. The cycle will repeat until ignition is turned off.

The 4WS indicator light will illuminate whenever a fault is sensed in system. Problem codes are stored in 4WS control unit even if condition is temporary. To retrieve problem codes, pull 2-pin service connector (Blue wires) from behind center console. Connect terminals with jumper wire. See Figure. 4WS indicator light will display problem codes. Record codes and address them in numerical order. The 4WS indicator light will NOT come on when Code 71, 72 or 73 is set. Indicator light will flash these codes, if stored, when code retrieval function is activated. See Figure - Figure .
