Turn the ignition switch OFF. Disconnect the EPS control unit connector C (20P). Turn the ignition switch ON (II). Does EPS indicator come on? YES - Repair short to ground in the YEL/BLU wire between the gauge assembly and the EPS control unit, or replace the bulb circuit board in the gauge assembly. NO - Go to step 12. Measure the voltage between the EPS control unit connector C (20P) terminal No. 10 and body ground. EPS CONTROL UNIT CONNECTOR C (20P) Wire side of female terminals Is there battery voltage? YES - Go to step 13. NO - Repair open in the wire between the EPS control unit connector C (20P) and No. 10 (7.5A) fuse.

Measure the voltage between the EPS control unit connector A (2P) terminal No. 1 and body ground. EPS CONTROL UNIT CONNECTOR A (2P) Wire side of female terminals Is there battery voltage? YES - Go to step 14. NO - Check for a blown No. 18 (60A) fuse in the under-hood fuse/relay box or open/short in the WHT/BLU wire between the under-hood fuse/relay box and the EPS control unit. Turn the ignition switch OFF. Reconnect the EPS control unit connector A (2P). Turn the ignition switch ON (II). Measure the voltage between the EPS control unit connector C (20P) terminal No. 8 and body ground. EPS CONTROL UNIT CONNECTOR C (20P) Wire side of female terminals Is there battery voltage? YES - Check for loose EPS control unit connectors. If necessary, substitute a known-good EPS control unit and retest. NO - Repair short to ground in the BRN wire between the data link connector (KB, KE, KG, TR models: service check connector) and the EPS control unit.
