NOTE: If DTCs irrelevant to the immobilizer are detected, perform diagnosis according to the DTCs irrelevant to the immobilizer first. 1. ECM
2. BODY INTEGRATED UNIT NOTE: Except for C0 and C5 models
NOTE: The starter relay control is performed in immobilizer system. When the body integrated unit detects a nonconformity of reference code, it immediately outputs a starter relay cut signal to ECM, and then ECM stops the starter relay operation. In this case, engine does not start, and DTC is not recorded in ECM. Check that the engine does not start on the DTC of body integrated unit. 3. IMMOBILIZER CM NOTE: For C0 and C5 models
NOTE: The starter relay control is performed in immobilizer system. When the immobilizer CM detects a nonconformity of reference code, it immediately outputs a starter relay cut signal to ECM, and then ECM stops the starter relay operation. In this case, engine does not start, and DTC is not recorded in ECM. Therefore, check DTC for the immobilizer CM to identify the cause of the engine not starting. |

Read diagnostic trouble code (dtc) operationDisassembly
NOTE:When replacing the coupling sleeve and synchronizer hub, replace them as a set. Because these must engage at the specified point, avoid disassembly as much as possible. If it is necessary to disassemble, mark the engaging points on the splines beforehand.1. Put vinyl tape around the main shaft ...
