Scheme 209: CHECKING THE COMPONENT AND WIRING

Check the engine speed (RPM) sensor connector. Check for contact resistance and oxidation. HINT: The components and its cables are sensitive to interference from nearby cables, such as the starter motor cable or a similar cable with a high current rating. Interference may cause difficult engine start, the engine does not start at all or intermittent function of the tachometer, etc. Check whether any cables with high power consumption are incorrectly installed, i. e. too close to the engine speed (RPM) sensor or its wiring. Check that the engine speed (RPM) sensor is correctly installed. Remedy as necessary.

REPLACING THE COMPONENT

Note. If the diagnostic trouble code (DTC) for sensors connected to 5 volt supply is stored, the diagnostic trouble code (DTC) must be fault-traced before this diagnostic trouble code (DTC).

The engine control module (ECM) has registered an internal fault.

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the engine control module (ECM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. Replace the engine control module (ECM) if the fault recurs.

Replace the engine control module (ECM) in the event of a permanent fault.

see ENGINE CONTROL MODULE (ECM)

FAULTY SIGNAL

See FAULTY SIGNAL

No fault-tracing has been developed for this diagnostic trouble code (DTC). The diagnostic trouble code (DTC) for this fault is stored first in the brake control module (BCM), then in the engine control module (ECM). This diagnostic trouble code (DTC) can not be erased before the diagnostic trouble code (DTC) in the brake control module (BCM) has been remedied and erased.

First read off the diagnostic trouble codes (DTCs) in the brake control module (BCM). Fault-trace and remedy as necessary. This diagnostic trouble code (DTC) can then be erased.

For further information about this diagnostic trouble code (DTC), select Information, then DTC information.

See FAULT-TRACING INFORMATION

Ignition on. Read off the diagnostic trouble code (DTC) status. Check whether the fault is permanent or intermittent.

The engine control module (ECM) has registered an internal fault.

Note. This diagnostic trouble code may have been stored incorrectly due to the Engine control module (ECM) considering that the battery voltage has been lower than normal. Newer software for Engine control module (ECM) has been made more durable and thus this problem cause is eliminated. Make sure that the Engine control module (ECM) has the latest software. Troubleshooting shall only continue if the control module already has the latest software.

Ignition off
Check the throttle unit and engine control module (ECM) connectors. Check for contact resistance and oxidation. Check the resistance values of the potentiometers in the throttle unit. Check the signal cable (potentiometer 1) between engine control module (ECM) terminal #A65 (#B5) and throttle unit terminal #6 (cable harness side). Check for an open-circuit. Check the signal cable (potentiometer 2) between engine control module (ECM) terminal #A88 (#B28) and throttle unit terminal #5 (cable harness side). Check for an open-circuit. Check the signal cables (potentiometer 1) terminal #A65 (#B5) and (potentiometer 2) terminal #A88 (#B28). Check for a short-circuit to each other.

CHECKING THE SIGNAL

Check whether any diagnostic trouble codes (DTCs) are stored in the brake control module (BCM) or in the central electronic module (CEM). If diagnostic trouble codes (DTCs) are stored in the brake control module (BCM) or in the central electronic module (CEM), these shall be taken care of first.

If there are any other diagnostic trouble codes (DTCs) stored for the brake pedal position sensor or for the stop lamp switch, fault-trace these first.

HINT: If diagnostic trouble code ECM-941C is stored in the engine control module (ECM), the brake pedal switch probably is or has been damaged.

Check the signals from the brake pedal switch and the brake pedal sensor during vehicle communication for the engine control module. The switch should be closed and the brake pedal sensor value should be updated when the brake pedal is depressed.

Check the cables for short-circuit to voltage, short-circuit to ground and open circuit.

Remedy as necessary.
