Test B: Memory Mirror Inoperative At Memory Set Switch

  1. Place transmission in Park. Turn ignition off. Connect New Generation Star (NGS) tester to data link connector. Retrieve and record DTCs. Clear continuous DTCs. Perform Driver Seat Module (DSM) on-demand self-test. If memory set switch LED does not illuminate during DSM self-test, go to step  5. If no DSM DTCs were retrieved, go to next step. If any DSM DTCs were retrieved, go to appropriate step. See DTC TO TEST STEP  table.
    DTC TO TEST STEP

    DTC Go To
    B1342 (1)
    B1529 Step  3
    B1533 Step  3
    B1537 Step  3
    B1667, B1668, B1669 & B1670 Concurrently Step  9
    B1667 Step  10
    B1668 Step  10
    B1669 Step  13
    B1670 Step  13
    (1) Replace Driver Seat Module (DSM).
  2. Monitor DSM PIDs MEM1_SW, MEM2_SW and MEM_SW, while operating memory set and recall switches. If PID values correspond to switch position, go to step  9. If PID values do not correspond to switch position and central junction box fuse No. 4 (15-amp) blows while operating switch, go to step  7. If PID values do not correspond to switch position and fuse No. 4 does not blow while operating switch, go to next step.
  3. Turn ignition off. Test memory set switch. See MEMORY SET SWITCH  under COMPONENT TESTS. If switch is okay, go to next step. If switch is defective, install new switch and check system for normal operation.
  4. Measure voltage between ground and memory switch harness connector terminal No. 1 (Orange/Light Green wire). See Figure. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Orange/Light Green wire and check system for normal operation. See WIRING DIAGRAMS .
  5. Turn ignition off. Measure resistance between ground and memory switch harness connector terminal No. 8 (Black/Light Blue wire). If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black/Light Blue wire and check system for normal operation. See WIRING DIAGRAMS .
  6. Disconnect DSM 22-pin harness connector. Turn ignition switch to RUN position. Measure voltage between ground and listed memory switch harness connector terminals. See MEMORY SET SWITCH TERMINAL IDENTIFICATION  table. If voltage does not exist at any terminal, go to next step. If voltage exists at any terminal, repair short to voltage in appropriate wire and check system for normal operation. See WIRING DIAGRAMS .
    MEMORY SET SWITCH TERMINAL IDENTIFICATION

    Terminal No. Wire Color
    3 Brown/Light Green
    4 Black/Orange
    6 Brown/Orange
    9 White/Orange
  7. Turn ignition off. Measure resistance between ground and listed terminals at memory switch harness connector. See MEMORY SET SWITCH TERMINAL IDENTIFICATION  table. If all resistance readings are greater than 10 k/ohms, go to next step. If any resistance reading is 10 k/ohms or less, repair short to ground in appropriate wire and check system for normal operation. See WIRING DIAGRAMS .
  8. Turn ignition off. Measure resistance in listed wires between memory switch harness connector and DSM 22-pin harness connector. See MEMORY SET SWITCH CIRCUIT IDENTIFICATION  table. See Figure and Figure . If all resistance readings are 5 ohms or less, replace DSM. If any resistance reading is greater than 5 ohms, repair open in appropriate wire and check system for normal operation. See WIRING DIAGRAMS .

    3 6 Brown/Orange
    13 9 White/Orange
    15 4 Black/Orange
    16 3 Brown/Light Green
  9. Monitor PIDs DMIR_R, DMIR_UP, PMIR_R and PMIR_UP, while using NGS tester to operate both side mirrors through all positions. If PID values agree with mirror actual positions, replace DSM. If PID values do not agree with driver side mirror actual positions, go to next step. If PID values do not agree with passenger side mirror actual positions, go to step  13.
  10. Turn ignition off. Disconnect DSM 22-pin harness connector. Disconnect driver side mirror harness connector. Turn ignition switch to RUN position. Measure voltage between ground and listed terminals at driver side mirror harness connector. See DRIVER MIRROR TERMINAL IDENTIFICATION  table. See Figure. If voltage does not exist at any terminal, go to next step. If voltage exists at any terminal, repair short to voltage in appropriate wire and check system for normal operation. See WIRING DIAGRAMS .

  11. Turn ignition off. Measure resistance between ground and listed terminals at driver side mirror harness connector. See DRIVER MIRROR TERMINAL IDENTIFICATION  table. If all resistance readings are greater than 10 k/ohms, go to next step. If any resistance reading is 10 k/ohms or less, repair short to ground in appropriate wire and check system for normal operation. See WIRING DIAGRAMS .
  12. Turn ignition off. Measure resistance in listed wires between driver side mirror harness connector and DSM 22-pin harness connector. See DRIVER MIRROR CIRCUIT IDENTIFICATION  table. See Figure and Figure . If all resistance readings are 5 ohms or less, replace driver mirror assembly. If any resistance reading is greater than 5 ohms, repair open in appropriate wire and check system for normal operation. See WIRING DIAGRAMS .
