-------------------------------------------------

Frozen values and counter for diagnostic trouble codes.
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. Driving conditions may be, e.g., if the engine was running, what speed the vehicle had, or how long the driving distance was.

Counter
The counters are used to determine the problem's status. For general information about the counters, see: Counters, description Description of Counter
Counter 1 indicates the number of drive cycles without fault since the fault was last validated.
If counter 1 is the same as 0, this means that the fault has been detected in this operating cycle (permanent fault). If no troubleshooting or repair has been performed in the vehicle in this driving cycle, the problem is probably in the vehicle.
If counter 1 is over 0, this indicates that the problem has not been detected in this driving cycle (intermittent problem). The problem has existed earlier but is not active right now.
Then check counter 4. Counter 4indicates number of driving cycles with problem since the problem was validated for the first time.
If the number of driving cycles with problems is high, this indicates an intermittent recurring problem, which means greater possibility of regenerating the problem in the workshop.
If the number of driving cycles with problems is low, this indicates an intermittent temporary problem, which means small possibility of regenerating the problem.

Hint: Counter 3 indicates number of driving cycles since first time that the problem occurred. If the value for counter 3 is divided by the value for counter 4, the intensity of the problem is obtained. The higher the value, the higher the problem intensity. A high problem intensity indicates that the malfunction recurs often.

Counter 5 can be used for more exact determination of when the problem occurred. To compare counter 5 for diagnostic trouble codes indicates in which order the diagnostic trouble codes were stored.

5-cyl. non-turbo engines
For model year 1999, only counter 1 and 2 are available.

Frozen values
The frozen values show the driving conditions when the control module detected the problem the first time. Check using the frozen values that the diagnostic trouble code has not been caused accidentally during troubleshooting of the vehicle. If the driving distance is 0 km/miles, this indicates that the problem has occurred at the control modules' start-up of the CAN-net, when reception of a relevant value has not been possible. This also applies to other values that come via the CAN-network. In these cases, counter 5 can be used to determine when the problem was generated.
If the diagnostic trouble code has been caused during this troubleshooting, it may be due to, e.g., disconnected component, too low or high battery voltage, or that some control module has been disconnected.
If the diagnostic trouble code has been stored since before, there has likely been a problem or interference, which has resulted in the control module detecting a problem.

Checking components
If the engine control module (ECM) registers that the signals from the steering wheel buttons indicate that they are all pressed simultaneously (which is impossible due to button design) for 0.3 seconds, diagnostic trouble code ECM-9200 Faulty signal is generated. Using VIDA vehicle communication, check that the parameters "Cruise control ON/OFF button", "Cruise control resume button", "Cruise control SET- button" and "Cruise control SET+ button" indicate correct values. If all parameters indicate ON, the fault is permanent. If the buttons work properly, the fault is intermittent.

Permanent fault
Check whether the steering wheel module (SWM) has stored any diagnostic trouble codes that indicate a fault in the cruise control buttons. Any diagnostic trouble codes that are stored should be fault traced first. If the steering wheel module (SWM) does not contain any diagnostic trouble codes indicating a fault in the cruise control buttons, check the buttons' electric switch and the connection to the contact reel in the steering wheel for short circuits and open circuits.

Intermittent fault
Use the diagnostic trouble code's frozen values, status identifiers and counter to determine the operating conditions when the fault was detected, the fault's current status and any degree of intermittence of the fault. The values show the problem's current status and how intermittent the problem is. The operating conditions can be, for example, whether the engine was running, what the speed of the vehicle was and what the battery voltage in the system was. If for example the trouble code was stored when battery voltage was low and engine speed was equal to 0 rpm, it could indicate that the fault arose when the vehicle was stationary with the ignition on for a long period, thereby draining the battery, or that the fault arose when the customer was attempting to start the vehicle.

Hint: Using VIDA vehicle communication, check that the parameters "Cruise control ON/OFF button", "Cruise control resume button", "Cruise control SET- button" and "Cruise control SET+ button" indicate correct values.

For markets where upgraded software, released during year 2006 or later, is available, the solution may be to download the upgraded software. Since detection time has been increased from 0.3 to 1.8 seconds, the upgraded software will be more tolerant to short, intermittent disruptions.
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 deleting diagnostic trouble codes and any reconfiguration may remain, despite the problem being fixed.
