DTC 112 - Fault In ECM
WARNING: This page is about a different car, the 1996 Volvo 850. However, it is still accessible from the selected car via links, so may be relevant.
- If ECM detects a fault in ROM/EPROM or RAM memory circuits, circuit for ECM's temperature sensor, knock control circuit, or ECT sensor circuit's NTC coupling, DTC 112 is set. If DTCs 432 and 513 are also present, go to testing for those DTCs. If these DTCs are not present, go to next step.
- If fault is permanent and signal is faulty, replace ECM. If fault is intermittent and signal is faulty, erase DTC. If DTC reoccurs, check ECM connector for good terminal contact. If terminal contact is okay, replace ECM.
