Test C: No Module Response On Circuit 914 Or Circuit 915

  1. Repeat DATA LINK DIAGNOSTIC TEST under COMMUNICATIONS NETWORK DIAGNOSTICS. If NGS tester displays 000000003 for both circuits 914 and 915, go to step 3). If NGS tester does not display 000000003 for both circuits 914 and 915, go to next step.
  2. If NGS tester displays 000000003 for circuit 914, go to step 6). If NGS tester displays 000000003 for circuit 915, go to step 10).
  3. Inspect Data Link Connector (DLC) for physical damage, bent terminals or corrosion. Repair as necessary and retest system for normal operation. If connector is okay, go to next step.
  4. Measure resistance between terminals No. 2 (Tan/Orange wire) and No. 10 (Pink/Light Blue wire) at DLC. See Figure. If resistance is less than 5 ohms, go to step 14). If resistance is 5 ohms or more, go to next step.
  5. Disconnect PCM connector located behind right side of instrument panel. Measure resistance of Tan/Orange wire between terminal No. 16 at PCM connector and terminal No. 2 at DLC. See Figure and Figure. Also, measure resistance of Pink/Light Blue wire between terminal No. 15 at PCM connector and terminal No. 10 at DLC. If both resistance readings are less than 5 ohms, go to next step. If any resistance reading is 5 ohms or more, repair open Tan/Orange wire and/or Pink/Light Blue wire between PCM connector and DLC. Retest system for proper operation.
  6. Inspect DLC for physical damage, bent terminals or corrosion. Repair as necessary and retest system for normal operation. If connector is okay, go to next step.
  7. Disconnect PCM connector located behind right side of instrument panel. Measure resistance of Tan/Orange wire between terminal No. 16 at PCM connector and terminal No. 2 at DLC. See Figure and Figure. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Tan/Orange wire between PCM connector and DLC. Retest system for proper operation.
  8. Measure voltage between terminals No. 2 (Tan/Orange wire) and No. 4 (Black wire) at DLC. If no voltage is indicated, go to step 14). If any voltage is indicated, go to next step.
  9. Measure voltage between terminals No. 2 (Tan/Orange wire) and No. 16 (Orange/Light Green wire) at DLC. If no voltage is indicated, go to step 14). If any voltage is indicated, repair or replace NGS tester.
  10. Inspect DLC for physical damage, bent terminals or corrosion. Repair as necessary and retest system for normal operation. If connector is okay, go to next step.
  11. Disconnect PCM connector located behind right side of instrument panel. Measure resistance of Pink/Light Blue wire between terminal No. 15 at PCM connector and terminal No. 10 at DLC. See Figure and Figure. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Pink/Light Blue wire between PCM connector and DLC. Retest system for proper operation.
  12. Measure voltage between terminals No. 10 (Pink/Light Blue wire) and No. 4 (Black wire) at DLC. If no voltage is indicated, go to next step. If any voltage is indicated, go to next step.
  13. Measure voltage between terminals No. 10 (Pink/Light Blue wire) and No. 16 (Orange/Light Green wire) at DLC. If no voltage is indicated, go to next step. If any voltage is indicated, repair or replace NGS tester.
  14. Disconnect 42-pin harness connector C100 located in left rear engine compartment, right of brake master cylinder. Repeat DATA LINK DIAGNOSTIC TEST under COMMUNICATION NETWORK DIAGNOSTICS. If NGS tester displays 0001, go to next step. If NGS tester does not display 0001, go to step 16).
  15. Reconnect connector C100. Disconnect PCM connector located behind right side of instrument panel. Repeat DATA LINK DIAGNOSTIC TEST under COMMUNICATION NETWORK DIAGNOSTICS. If NGS tester displays 0001, replace PCM. Repeat DATA LINK DIAGNOSTIC TEST to confirm repair. If NGS tester does not display 0001, repair Tan/Orange wire and/or Pink/Light Blue wire between PCM connector and connector C100. Repeat DATA LINK DIAGNOSTIC TEST to confirm repair.
  16. Reconnect all wiring harness connectors. Disconnect Anti-lock Brake/Traction Control (ABS/TC) module connector located in left rear of engine compartment. Repeat DATA LINK DIAGNOSTIC TEST under COMMUNICATION NETWORK DIAGNOSTICS. If NGS tester displays 0002, replace ABS/TC module. Repeat DATA LINK DIAGNOSTIC TEST to confirm repair. If NGS tester does not display 0002, repair Tan/Orange wire and/or Pink/Light Blue wire between DLC and ABS/TC module connector. Reconnect all wiring harness connector and repeat DATA LINK DIAGNOSTICS to confirm repair.
