Diagnostic procedure

NO. 8 HILL LAUNCH ASSIST (HLA) OPERATES EVEN ON DOWNHILL/HILL LAUNCH ASSIST (HLA) DOES NOT OPERATE ON SLOPE DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY DTC FOR RELATED MODULES Retrieve the DSC HU/CM, PCM, TCM (ATX) and instrument cluster DTC using the M-MDS. (See DTC INSPECTION [DYNAMIC STABILITY CONTROL (DSC)] .) (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (FW6A-EL, FW6AX-EL)] .) (See DTC INSPECTION [INSTRUMENT CLUSTER] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)] .) (See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (FW6A-EL, FW6AX-EL)] .) (See DTC TABLE [INSTRUMENT CLUSTER] .)
1		No	Go to the next step.
2	VERIFY IF FALSE DETECTION OF INCLINATION ANGLE CAUSED BY MALFUNCTIONING SAS CONTROL MODULE INSTALLATION Inspect the SAS control module installation condition for the following: Is the module installed with any twisting? Is the module installed correctly?	Yes	Go to the next step.
2		No	Repair the SAS control module installation condition. (See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM - MEXICO SPEC.] .) (See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .)
3	VERIFY IF MALFUNCTION CAUSED BY INITIALIZATION PROCEDURE FOR LOW-G SENSOR NOT PERFORMED Verify if malfunction caused by initialization procedure for low-G sensor not performed. Has the initialization for the low-G sensor been performed after replacing the DSC HU/CM and the SAS control module?	Yes	Go to the next step.
3		No	Perform the initialization procedure. (See DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE .)
4	VERIFY IF MALFUNCTION CAUSED BY TIRE MALFUNCTION PERFORMED Inspect the tire pressure and condition. Are tire pressure and condition normal?	Yes	Go to the next step.
4		No	If the pressure is incorrect, adjust the tire pressure to the specification. If the tires are worn, replace the tires.
5	INSPECT RELATED MODULES FOR MALFUNCTION CAUSED BY FALSE SIGNAL Access the following DSC HU/CM, PCM and instrument cluster PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION [DYNAMIC STABILITY CONTROL (DSC)] .) (See PCM INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) (See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [TCM (FW6A-EL, FW6AX-EL)] .) (See PID/DATA MONITOR INSPECTION [INSTRUMENT CLUSTER] .) DSC HU/CM BRAKE_SW (Brake signal) LON_ACCL_C (Low-G sensor (longitudinal G) calculated value signal) LON_ACCL_R (Low-G sensor (longitudinal G) raw value signal) BRK_F_P_C (Brake fluid pressure calculated value signal) BRK_F_P_R (Brake fluid pressure raw value signal) WSPD_LF (ABS wheel-speed sensor (LF) signal) WSPD_RF (ABS wheel-speed sensor (RF) signal) WSPD_LR (ABS wheel-speed sensor (LR) signal) WSPD_RR (ABS wheel-speed sensor (RR) signal) PCM RPM (Engine speed signal) APP (APP sensor signal) CPP (Clutch pedal signal: MTX) M_GEAR (Manual gear position signal: MTX) GEAR (Gear commanded signal: ATX) TCM (ATX) TR (Transaxle range sensor signal) INSTRUMENT CLUSTER P_BRAKE_SW (Parking brake signal) Are all PID values normal?	Yes	Inspect the following: Brake (foot brake/parking brake) drag Engine output malfunction Repair or replace any malfunctioning parts according to the inspection result.
5		No	Inspect the related parts and wiring harness. Repair or replace any malfunctioning parts according to the inspection result.
