Diagnosis & Repair Procedure

  1. If engine system check has been performed, go to next step. If engine system check has not been performed, go to A4: ENGINE SYSTEM CHECK  under SYSTEM TESTS.
  2. If SUZUKI scan tool is not available, go to next step. If using SUZUKI scan tool, turn ignition on and shift through all gear positions while observing PNP SIGNAL SPECIFICATION on scan tool. If "D" (zero-one volt indicated) range is not present in all gear positions except Park and Neutral, go to step  4 . If "D" range is present in all gear positions except Park and Neutral, problem is probably intermittent. See problem is probably intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
  3. Backprobing at ECM, measure voltage between ground and ECM 22-pin harness connector E92 terminal No. 15 (Gray/Red wire). See Figure . Turn ignition on and shift transmission through all gear positions while observing voltmeter. If 0-1 volts is not present in all gear positions except Park and Neutral, go to step  5 . If 0-1 volts is present in all gear positions except Park and Neutral, problem is probably intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
  4. Turn ignition on, shift through all gear positions while observing scan tool. If P/N range is present in only Park and Neutral gear position, go to step  6 . If P/N range is present in any gear position besides Park and Neutral. Check transmission range sensor and circuits operation. See TRANSMISSION RANGE SENSOR under ENGINE SENSORS & SWITCHES in SYSTEM & COMPONENT TESTING article.
  5. Backprobing at ECM, measure voltage between ground and ECM 22-pin harness connector E92 terminal No. 15 (Gray/Red wire). See Figure . With ignition on, shift through all gear positions while observing voltmeter. If 10-14 volts is present in only Park and Neutral gear position, go to next step. If 10-14 volts is present in any gear position besides Park and Neutral. Check transmission range sensor and circuits operation. See TRANSMISSION RANGE SENSOR under ENGINE SENSORS & SWITCHES in SYSTEM & COMPONENT TESTING article.
  6. Turn ignition off. Disconnect TCM 20-pin harness connector E26. TCM is located under dash, and is attached to bracket near steering column. Turn ignition on. Check for poor terminal connection at TCM. If problem is found, repair as necessary. If no problem is found, go to next step.
  7. Turn ignition on. Measure voltage between ground and TCM 20-pin harness connector E26 terminal No. 10. See Figure . If battery voltage exists, go to next step. If battery voltage does not exist, go to step  10 .
  8. Check for open or poor terminal connection in Brown/Yellow wire between Park Neutral Position (PNP) switch and ignition switch. See WIRING DIAGRAMS article. If problem is found, repair as necessary. After repair, repeat DTC CONFIRMATION TEST  . If no problem is found with wiring, go to next step.
  9. Check transmission range sensor adjustment. See appropriate procedure in ON-VEHICLE ADJUSTMENTS article. After repair, repeat DTC CONFIRMATION TEST  . If sensor adjustment is okay and no problem was found in wiring, substitute a known good TCM, and repeat DTC CONFIRMATION TEST  . If DTC does not reset, testing is complete.
  10. Turn ignition off. Disconnect ECM 22-pin harness connector E92. ECM is located under instrument panel, behind glove box. See Figure . Check for open or poor terminal contact in Gray/Red wire between ECM harness connector E92 terminal No. 15 and TCM. If problem is found, repair as necessary. After repair, repeat DTC CONFIRMATION TEST  . If no problem is found, go to next step.
  11. Substitute a known good ECM, and repeat DTC CONFIRMATION TEST  . If DTC does not reset, testing is complete.
