DTC 76 - Resume/ACCEL Switch Fault: Notes

The cruise ON/OFF, SET/COAST and RESUME/ACCEL switches are inputs to the fuel control portion of the PCM. These inputs allow the PCM to control and hold a requested speed. The resume/accel request signal circuit supplies ignition voltage to the PCM when resume/accel is depressed. DTC 76 will set when:

Cruise control is on.
Ignition voltage on the resume/accel request signal circuit is present for more than 25.5 seconds.

PCM will default to the PCM disallowing all cruise inputs. TCC shift schedules may be affected.

NOTE: Test numbers refer to numbers on diagnostic chart.

This step determines if the resume/accel request signal circuit is shorted to voltage.
This step determines if the PCM or switch is at fault.
