Diagnostic procedure

NO. 7 HILL LAUNCH ASSIST OPERATES EVEN ON DOWNHILL/HILL LAUNCH ASSIST DOES NOT OPERATE ON SLOPE (DYNAMIC STABILITY CONTROL) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	VERIFY DTC FOR RELATED MODULES Retrieve the DSC HU/Control Module, PCM, TCM (ATX) and instrument cluster DTC using the M-MDS. (See DTC INSPECTION .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [DSC HU/Control Module (US)] .) (See DTC TABLE [PCM (VINs 7, L, M) (US)] .) (See DTC TABLE [PCM (VIN Y)] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (GW6AX-EL) (US)] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (ET6A-EL ) (US)] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (EV6A-EL, EV6AX-EL) (US)] .) (See DTC TABLE [BODY CONTROL MODULE (BCM) (US)] .) (See ON-BOARD DIAGNOSTIC TEST MODE [TCM (EV6A-EL, EV6AX-EL)] .) (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (EV6A-EL, EV6AX-EL) (US)] .)
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, and perform the repair completion verification. (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/Control Module and the SAS control module?	Yes	Go to the next step.
3		No	Perform the initialization procedure, and perform the repair completion verification. (See DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE (US) .)
4	VERIFY IF MALFUNCTION CAUSED BY TIRE MALFUNCTION PERFORMED Inspect the tire pressure and condition. Are tire pressure and condition normal? (See WHEEL AND TIRE SPECIFICATION (US) .)	Yes	Go to the next step.
4		No	If the pressure is incorrect, adjust the tire pressure to the specification. (See TIRE PRESSURE ADJUSTMENT (US) .) If the tires are worn, replace the tires. Perform the repair completion verification.
5	INSPECT RELATED MODULES FOR MALFUNCTION CAUSED BY FALSE SIGNAL Access the following DSC HU/Control Module, PCM and TCM PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION .) DSC HU/Control Module BRK_PEDAL_SW (Brake signal) ACC_LON_C (Low-G sensor (longitudinal G) calculated value signal) ACC_LON (Low-G sensor (longitudinal G) raw value signal) BRK_FLD_PRES (Brake fluid pressure raw value signal) WSPD_SEN_L/F (ABS wheel-speed sensor (LF) signal) WSPD_SEN_R/F (ABS wheel-speed sensor (RF) signal) WSPD_SEN_L/R (ABS wheel-speed sensor (LR) signal) WSPD_SEN_R/R (ABS wheel-speed sensor (RR) signal) PCM ENG_RPM (Engine speed signal) APP1 (APP sensor signal) CLTCH_PEDAL_POS (Clutch pedal signal: MTX) MANUAL_GEAR_POS (Manual gear position signal: MTX) TCM (ATX) SFTR_DOWN (Transaxle range sensor signal) SFTR_UP (Transaxle range sensor signal) SHIFT_D (Transaxle range sensor signal) SHIFT_N (Transaxle range sensor signal) SHIFT_P (Transaxle range sensor signal) SHIFT_R (Transaxle range sensor signal) SHIFT_A_M (Transaxle range sensor signal) Are all PID values normal?	Yes	Inspect the followings: Brake (foot brake/parking brake) drag Engine output malfunction Repair or replace any malfunctioning parts according to the inspection result. Perform the repair completion verification.
5		No	Inspect the related parts and wiring harness. Repair or replace any malfunctioning parts according to the inspection result. Perform the repair completion verification.
Repair completion verification	VERIFY THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR Install/connect the part removed/disconnected during the troubleshooting procedure. Has the malfunction symptom been eliminated?	Yes	Complete the symptom troubleshooting. Explain to the customer what has been repaired.
Repair completion verification		No	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW (US) .) If the CAN communication is normal, perform the diagnosis from Step 1.
