00-7 GENERAL HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS TROUBLESHOOTING CONTENTS DANGER The SRS-ECU adopts the rollover specification that the curtain air bag and seat belt pre-tensioner operate at the occurrence of rollover. Therefore, do not tilt the vehicle to the right and left with the IG ON or tilt the SRS-ECU to the right and left with the IG ON and the harness installed. CAUTION During diagnosis, a diagnostic trouble code associated with other system may be set when the ignition switch is turned "ON" with connector(s) disconnected. On completion, confirm all systems for diagnostic trouble code(s). If diagnostic trouble code(s) are set, erase them all. WARNING Since the radiator fan rotates during CAN bus line diagnostics, make sure that no one is servicing the engine compartment before diagnosing the CAN bus line. Since the CAN communication stops when diagnosing the CAN bus line, the ETACS-ECU detects the time-out of the engine control module, and activates the radiator fan to prevent overheating as fail-safe. 1. STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING Troubleshooting sections are based on the diagnostic flow as below. If the diagnostic flow is different from that given below, or if additional explanation is required, the details of such differences or additions will also be listed. TSB Revision M1001013300653 Troubleshooting of electronic control systems for which scan tool MB991958 can be used follows the basic outline described below. Even in systems for which scan tool MB991958 cannot be used, some of these systems still follow this outline.
