\n
1<\/div>\n<\/td>\n
\n
VERIFY EPS CONTROL MODULE DTCs<\/div>\n
\u2022 Switch the ignition off and maintain this condition approx. 1 minute<\/span>.<\/div>\n
\u2022 Switch the ignition ON (engine on).<\/div>\n
\u2022 Perform the DTC inspection. (See DTC INSPECTION<\/a>.)<\/div>\n
\u2022 Are any DTCs present?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to the applicable DTC inspection.<\/div>\n
(See DTC TABLE [ELECTRIC POWER STEERING (EPS) (US)]<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
2<\/div>\n<\/td>\n
\n
VERIFY ELECTRIC POWER STEERING WARNING LIGHT ILLUMINATION CONDITION<\/div>\n
\u2022 Ignition is switched ON (engine off)<\/div>\n
\u2022 Does the EPS warning light\/master warning light turn off?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Malfunction may be temporary.<\/div>\n<\/td>\n<\/tr>\n
\n
3<\/div>\n<\/td>\n
\n
VERIFY COMMUNICATION CONDITION BETWEEN EPS CONTROL MODULE AND BODY CONTROL MODULE (BCM)<\/div>\n
\u2022 Using the M-MDS, display the following PIDs for the body control module (BCM). (See PID\/DATA MONITOR INSPECTION<\/a>.)<\/div>\n
\n
\n
\u2015 EPAS_NETWORK<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Is the EPAS_NETWORK PID value Node Attached and Communicate correctly?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Perform the body control module (BCM) configuration, then repeat the inspection from Step 1.<\/div>\n
If the malfunction recurs, replace the instrument cluster.<\/div>\n
(See INSTRUMENT CLUSTER REMOVAL\/INSTALLATION<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
EPS control module malfunction. Replace the EPS control module.<\/div>\n
(See STEERING WHEEL AND COLUMN REMOVAL\/INSTALLATION [(US)]<\/a>.)<\/div>\n
Perform the repair completion verification.<\/div>\n<\/td>\n<\/tr>\n
\n
Repair completion verification<\/div>\n<\/td>\n
\n
VERIFY THAT MALFUNCTION SYMPTOMS DO NOT RECUR AFTER REPAIR<\/div>\n
\u2022 Install\/connect the part removed\/disconnected during the troubleshooting procedure.<\/div>\n
\u2022 Has the malfunction symptom been eliminated?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Complete the symptom troubleshooting.<\/div>\n
Explain to the customer what has been repaired.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.<\/div>\n
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)]<\/a>.)<\/div>\n
If the CAN communication is normal, perform the diagnosis from Step 1.<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
