Scheme 113

1. DESCRIPTION Vehicle ECUs store trouble codes when malfunctions occur. The diagnostic system allows for reading of the trouble codes from the DLC3. Use the Techstream to check and solve the problem.
2. CHECK DLC3 Check the DLC3. Refer to «GENERAL INFORMATION [03/2012 - ]»(ref-602551-S10595751552014030500000) .
3. CHECK DIAGNOSTIC FACTOR INDICATION NOTE: Turn the engine switch off before performing the diagnostic function. If the diagnostic connectors are not connected, the remote engine starter system will not enter diagnostic mode. HINT: The diagnostic mode will finish when either of the following conditions is met: The diagnostic connectors are disconnected. 10 minutes elapse after the time the diagnostic connectors were connected. To prepare the vehicle for diagnostic mode, connect the diagnostic connectors. The steps are as follows. Remove the front door scuff plate RH. Refer to «REMOVAL [03/2012 - 07/2012]»(ref-602734-S33529861002014030500000) . Remove the cowl side trim sub-assembly RH. Refer to «REMOVAL [03/2012 - 07/2012]»(ref-602734-S33529861002014030500000) . Find and connect the diagnostic connectors (labeled RDIG), located in the passenger cowl area. Perform the following steps to enter diagnostic mode after connecting the diagnostic connectors. Turn the engine switch from off to on (IG) and wait more than 3 seconds. Depress the brake pedal. The diagnostic mode is entered after the hazard lights flash. HINT: Confirm the factor that caused the engine to stop by checking the number of times the hazard lights flash. The diagnostic mode indicates the causes of the engine stop or failure to start by flashing the hazard lights as listed below. ENGINE STOP FACTOR Engine Stop Factor Number of Flashes Order of Priority No abnormal stop in the past 0 0 Engine switch on (ACC or IG) 1 1 Any door is unlocked 2 4 Engine speed is too high or low 3 7 Any door or engine hood is opened 5 2 Shift lever is not in P 6 5 Brake pedal is depressed 7 3 Vehicle speed is abnormal 8 6 Immobiliser collation discrepancy 9 9 HINT: When two or more of these conditions are responsible for the engine stop or failure to start, they will be indicated in the order of priority. The remote engine starter will store the code for the last engine stop factor in its memory, even after exiting the diagnostic mode. The code can not be cleared from the remote engine starter ECU. The engine stop factor that flashes the hazard lights 4 times does not occur for this type of vehicle.

DATA LIST / ACTIVE TEST [03/2012 - ]

1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. NOTE: In the following table, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Enter the following menus: Body Electrical / Remote Engine Starter / Data List. Read the Data List according to the display on the Techstream.
