The pre-return checklist
Work these in order. Each one on its own has resolved installs we were sure were bad modules.
-
Soft reset
Perform this task even if you’ve already done so once. Follow the sequence exactly — the timing matters.
Key ignition
-
Insert key into ignition.
-
Turn key to the ON position — just short of cranking. Don’t crank.
-
Hold for 120 seconds. Then turn off and remove the key.
Push-to-start
-
Push the Start button 2×.
-
Wait 120 seconds.
-
Push the Start button again and start as normal.
-
-
Reconnect all cables
Disconnect your battery cables and the ECM cables, then reconnect everything. Make sure every plug is fully seated — a single loose cable can trigger a whole range of symptoms.
-
Battery cables check
Check that your battery cables are securely attached and tightly fastened; a loose battery post causes the same faults. Then check the state of charge — optimally 12.6 volts or more after the vehicle has been sitting overnight.
-
Clear codes
Make an attempt to clear any engine codes, if possible, and re-test the vehicle.
