Trouble Code E.7.6
Cruise control "SET/COAST" switch sends 12 volt signal to ECM when "SET/COAST" switch is depressed.
NOTE:
The following step numbers refer to the numbers in the accompanying flow chart(s).
- Code indicates that ECM is not receiving 12 volt signal from "SET/COAST" switch when it is depressed. Rerun switch test. To begin diagnosis, turn ignition on and cruise enable switch on. Connect voltmeter (J-29125) between pin F of Orange ECM connector and ground.
- If voltage on pin F reads 12 volts, disconnect Orange ECM connector and measure voltage on pin F again. If voltage reads 12 volts, check circuit No. 84 for short to voltage. If circuit No. 84 is okay, replace "SET/COAST" switch. If voltage on pin F is 0 volts, check for faulty ECM connector or faulty ECM.
- While depressing "SET/COAST" switch, measure voltage on pin F of Orange ECM connector again. If voltage is 0 volts, check circuit No. 84 for open or short to ground and circuit No. 397 for open. If circuit Nos. 84 and 397 are okay, replace "SET/COAST" switch. If voltage on pin F is 12 volts, then check for faulty ECM connector or faulty ECM because it is not processing 12 volt signal.
