ECM-9A0A

Description of behaviors, ECM-9A0A
The purpose of this information is to provide a brief description of the types of negative behavior that may be observed in the car when diagnostic trouble code (DTC) ECM-9A0A is stored in the engine control module (ECM). Scope, frequency and magnitude of a behavior depend on a large number of parameters and circumstances, which can result in variations from case to case.

Hint: Combinations of behaviors can occur.

Behavior 1
- Cruise control is active. CRUISE-the lamp lights, but the buttons SET+, SET- and RESUME do not work.

Behavior 2
- The cruise control does not function at all. The CRUISE lamp goes out.

Behavior 3
- When the brake and accelerator pedal are depressed simultaneously, the function of the accelerator pedal is ignored.

Behavior 4
- Runs slightly jerkily.

Behavior 5
- Jerky operation. Uneven idle.

Behavior 6
- The relationship between the accelerator pedal and the throttle has the same characteristics as a system controlled by a mechanical cable.
Uneven idle.

Behavior 7
- Poor performance. The engine dies.

Behavior 8
- The behavior means that the Engine control module (ECM) does not permit auto start.
Occurs during the following fault causes:
- Due to the information from the Brake control module (BCM), the Engine control module (ECM) does not permit auto start.
- Fault in the clutch pedal sensor and/or clutch pedal switch.
- Incorrect or missing speed signal from the Brake control module (BCM) / transmission control module (TCM)
- Fault in supply to starter relay.
- Missing signal from the gear position sensor (P/N indication).

Behavior 9
- The behavior means that the Engine control module (ECM) switches off the fuel pump.
Occurs during the following fault causes:
- If the starter motor relay is connected but the Engine control module (ECM) has permitted start.
- The Engine control module (ECM) receives speed signals from the Brake control module (BCM) within one second after start attempt.
