I am not familiar with code 19, but my code 26 is due to a faulty passive restraint control module. I have intermittent problems with the passenger side restraint. Heard a clicking sound under the console near the gear shifter (that is where the prcm is located). Thus, my code 26 is most likely the prcm. However, code 26 has 8 or so different possible explanations.

For the code 26, follow these trouble shooting steps.

DTC 26 Trouble Shooting.

1. Turn key to the ON position.
2. Do the light come ON and the SES light shut off? If YES go to next step. If NO:
-Check circuit(s) for voltage (fuse), short to ground, open wire or bulb.
3. Ground ALDL A to B. Is coolant fan running? If YES go to next step. If NO:
-Check circuit for voltage, (fuse), or open. Coolant fan relay resistance 70-90 ohms.
4. Remove ALDL ground. Start engine. Turn on A/C.
5. Does A/C clutch operate? If YES go to next step. If NO:
-Check circuit for voltage, (fuse), or open. A/C relay resistance 70-90 ohms.
6. Does the speedometer operate correctly? If YES go to next step. If NO:
-Check circuit(s) for voltage (fuse), short to ground, or open wire.
7. Disconnect PCM and ground circuit 456.
8. Does upshift (man) or shift to D2 (auto 1991-1992) or traction control telltale light?
If YES go to next step. If NO:
-Check circuit(s) for voltage (fuse), short to ground, open wire or bulb.
9. Measure voltage at circuits 428 and 435 at PCM harness connector.
10. Is voltage present on both circuits? If YES go to next step. If NO:
-Check circuit(s) for voltage(fuse)m short to ground, open wire or solenoid(s).
11. Key OFF. Measure resistance of EGR and EVAP canister purge solenoid. EGR
should be 20-50 ohms;EVAP canister should be 20-50 ohms.
12. Are solenoids within specification? If YES go to next step. If NO:
-Shorted solenoid(s).
13. Put vehicle on lift or on jackstands securely enough and high enough to allow
wheels to spin. Leave driver's sode door open, start vehicle, place in DRIVE and
slowly increas vehicle speed to 24 km/h (15 mph).
14. Does vehicle drivers belt move from A-pillar to the B-pillar? If YES go to next step. If NO:
-Check circuit 817 to passive restraint module for open or shorts.
-Is circuit 817 OK? If YES Check terminal tightness or passive restraint module. If NO:
-Repair circuit 817.
15. Reconnect PCM. Clear diagnostic trouble codes. Start engine.
16. Does DTC 26 reset? If NO go to next step. If YES:
-Terminal tightness or PCM.
17. Problem intermittent; see diagnostic aids
