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 Counters, Description
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 4 indicates 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.

As described in the diagnostic trouble code information, this diagnostic trouble code is stored when the engine's current torque exceeds a maximal permitted torque for a short time. The diagnostic trouble code may be stored alone or exists as a subsequent problem of any another diagnostic trouble code.
If any of the diagnostic trouble codes ECM-1300, ECM-130A, ECM-260A, ECM-261A, ECM-262A, ECM-270A, ECM-271A, ECM-272A, ECM-6800, ECM-6805 and/or ECM-6806 are stored together with ECM-981A, continue troubleshooting according to any of these diagnostic trouble codes. Otherwise, continue as follows.
If there is no other diagnostic trouble code that indicates what may have caused exceeding of the engine's torque, then use the frozen values to try to determine when the problem occurred and what has caused the high torque. Also check the counters to get an idea if it is likely that the problem can be recreated or not. 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. A damage to following components or system would mean that the engine's torque becomes too high.
- Check the intake system for air leakage and loose charge-air pipe.
- Check that the wastegate valve does not jam, that the turbo control valve is not damaged or that there are cracked or blocked hoses between the turbo control valve and intake manifold or wastegate valve.
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.
