P1700 CHEVROLET Description
This Diagnostic Trouble Code (DTC) indicates that a transmission related OBDII failure has occurred. Transmission Control Module (TCM) controls a dedicated service transmission light, which is illuminated when a failure is reported by certain non-emission related TCM diagnostics. TCM has no direct control of engine MIL, but if transmission fault occurs that is emission related, MIL must illuminate. A MIL request circuit between Engine Control Module (ECM) and TCM provides a means for illuminating MIL, even though the fault was detected by TCM. This circuit is increased to battery voltage within ECM. To illuminate MIL, TCM lowers circuit voltage. ECM detects this and DTC is set, which illuminates MIL. The DTC will set when an OBDII transmission DTC has been stored by TCM.
