DTC B2262: Left Mirror Horizontal Position Sensor Fault

WARNING: This page is about a different car, the 2000 Chevrolet Corvette, 1999 Chevrolet Corvette, and 1998 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. Go to next step.
  2. Using scan tool, select LDCM DTC display. If DTC B2262 is stored as a history code, go to next step. If DTC B2262 is not stored as a history code, go to step  8 .
  3. Using scan tool, select LDCM data display. Monitor horizontal position sensor data while operating left-side mirror. Mirror horizontal position sensor voltage should display 0.1-4.8 volts. If reading is not as specified, go to next step. If reading is as specified, check mirror horizontal position sensor circuit for poor connections or intermittent operation. See WIRING DIAGRAMS  . If mirror horizontal position sensor circuit checks okay, retest system. If DTC B2262 sets as a history code, go to step  11 .
  4. Turn ignition off. Disconnect left power mirror 4-pin connector C2. Turn ignition on. Using DVOM, check voltage between left power mirror harness connector C2 terminal "A" (Gray wire) and ground. See Fig 1 . If reading is 4.0-5.5 volts, go to next step. If reading is not 4.5-5.5 volts, go to step  7 .
  5. Check voltage between left power mirror harness connector C2 terminals "A" (Gray wire) and "C" (Black/White wire) while operating left-side mirror. If reading is 4.0-5.5 volts, go to next step. If reading is not 4.0-5.5 volts, go to step  9 .
  6. Replace left power mirror. See POWER MIRROR ASSEMBLY  under REMOVAL & INSTALLATION. Recheck system operation.
  7. Check for open , short to ground or short to voltage in Gray wire between left power mirror connector C2 terminal "A" and Left Door Control Module (LDCM) connector C1 terminal No. 5. Repair as necessary. Recheck system operation. If circuit is okay, go to step  11 .
  8. Turn ignition off. Disconnect left power mirror 4-pin connector C2. Turn ignition on. Using DVOM, check voltage between left power mirror harness connector C2 terminal "D" (Gray wire) and ground while operating left-side mirror. See Fig 1 . If reading is 3.5-5.5 volts, go to step  6 . If reading is not 3.5-5.5 volts, go to step  10 .
  9. Check for open or short to voltage in Black/White wire between left power mirror connector C2 terminal "C" and LDCM connector C1 terminal No. 6. See Figure . Repair as necessary. Recheck system operation. If circuit is okay, go to step  11 .
  10. Check for open, short to ground or short to voltage in Gray wire between left power mirror connector C2 terminal "D" and Left Door Control Module (LDCM) connector C1 terminal No. 15. See Figure . Repair as necessary. Recheck system operation. If circuit is okay, go to next step.
  11. Replace LDCM. See DOOR CONTROL MODULE  under REMOVAL & INSTALLATION.
