Possible causes, elimination, notes

Control module supply voltage too low (less than 9.5 V)

Normally, this fault occurs only when the engine is started in combination with a discharged battery.

Pull off the control module connector and measure the voltage between PIN 15 (plus) and PIN 19 (ground).
