For 5-cyl. normally aspirated engines.
If ECM-130A is stored together with ECM-91CF, ECM-130A must be fault-traced and remedied first. This is because ECM-91CF is incorrectly stored when ECM-130A, Permanent fault is stored, at the same time as cruise control is activated. This can be solved by fault-tracing and remedying ECM-130A. Otherwise, continue as follows.
For turbo engines and 6-cylinder aspirated engines:
If ECM-91CF is stored but not ECM-130A, the solution for the markets where upgraded software, released during 2006 or later, is available, can be to download the upgraded software. Modifications have been made in the upgraded software, that do not place great demands on the Electronic throttle module (ETM) and Engine control module (ECM) reacting at precisely the same time, several seconds can now pass until the diagnostic trouble code (DTC) is stored. In other words, if cruise control is activated using the upgraded software, and then the brakes are applied, the Electronic throttle module (ETM) permits up to 2 seconds to pass before the Engine control module (ECM) signals that cruise control is no longer active. The diagnostic trouble code (DTC) is stored after 0.5 seconds in earlier software. Otherwise, continue as follows.
If there is another diagnostic trouble code (DTC) in the Engine control module (ECM) that indicates a brake fault, ECM-9400 and/or ECM-914F, this/these must be fault-traced first. Otherwise, continue as follows.
Check, using VIDA vehicle communication, that the Engine control module (ECM) receives the correct information about the status of the stop lamp switch and brake pedal position sensor. If the parameter for the brake light switch indicates the wrong status, check the signal cable between the brake light switch and the engine control module (ECM) for open circuit.
Use the diagnostic trouble codes' frozen values as well as the counters, to determine the driving conditions when the problem was detected the first time and how often the problem has occurred. The values show the problem's current status and how intermittent the problem is. If the counters show that the problem has occurred frequently in recent time, it is highly likely that the problem can be recreated during troubleshooting. If the counters show that the problem is extremely intermittent, it is not very likely that the problem can be recreated during troubleshooting.
Remedy as necessary.

CAUTION: In order for Electronic throttle module (ETM) to reset any reconfigurations as well as delete internally stored problems, the following must be performed:
- Ignition off, wait three minutes so that the main relay / system relay releases the voltage feed to, among other, Electronic throttle module (ETM).
- Then turn on the ignition and turn it off again.
- Wait another three minutes, but if the electric cooling fan is running you have to wait another two minutes after the cooling fan has stopped, to ensure that Electronic throttle module (ETM) is shut off correctly.
If this is not done correctly, diagnostic trouble codes may remain even after deletion of diagnostic trouble codes as well as any reconfiguration, despite the problem being fixed.
