C1293

CIRCUIT DESCRIPTION
This Diagnostic Trouble Code (DTC) is the second portion of DTC C1291. If DTC C1291 occurred during the last ignition cycle, DTC C1293 becomes a current malfunction during the next ignition cycle, keeping the TCS disabled until a Stoplamp/BTSI switch On state is seen. When a change is seen during an ignition cycle in which DTC C1293 is a current malfunction, DTC C1291 will clear itself at the end of the current ignition cycle, and the TCS will enable at the start of the next ignition cycle. DTC C1293 alone indicates that DTC C1291 occurred previously, but is intermittent. or has been corrected.
