Checking components
If one or several of the diagnostic trouble codes (DTCs), ECM-900E, ECM-901A, ECM-901E, ECM-902A, ECM-902B, ECM-910E, ECM-911A, ECM-912A, ECM-E000 and/or ECM-E003 are stored together with ECM-913F, continue fault-tracing according to one of these diagnostic trouble codes (DTCs). Otherwise, continue as follows.
Check, using the identification of the upgraded software Engine control module (ECM)/Electronic throttle module (ETM) that the correct software is in the Electronic throttle module (ETM) and the Engine control module (ECM). The diagnostic trouble code (DTC) is stored if software that is not compatible is mixed. This can, for example, occur if the software in the Electronic throttle module (ETM) is older than the upgraded software in the Engine control module (ECM) or if a throttle unit, which is designed for a 5-cylinder turbocharged engine, is installed on a 5-cylinder non-turbocharged engine.
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 diagnostic trouble code (DTC) was stored under operating conditions that means external factors, such as low battery voltage during engine start-up, are suspected to be the cause fault-trace and remedy as necessary. If no external factors are suspected and if the fault is permanent, i. e. the fault has been detected several times, try a new Engine control module (ECM).
Remedy as necessary.
Other information
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. If the electric cooling fan is running, you have to wait another two minutes after the electric cooling fan has stopped, to make sure that Electronic throttle module (ETM) has been 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.
- Continue
