Set/Resume/Cancel Switch Test: 3.2TL
- Disable air bag system. Remove steering column covers. Disconnect SET/RESUME/CANCEL switch 4-pin connector. See Fig 1.
- With SET button in ON position, continuity should exist between cable reel 4-pin connector terminals No. 2 and 4. See Fig 1. With RESUME button in ON position, continuity should exist between cable reel 4-pin connector terminals No. 2 and 3. With CANCEL button in ON position, check for continuity by probing cable reel 4-pin connector terminal No. 2 with positive terminal of DVOM, and terminals No. 3 and 4 with negative terminal of DVOM. With CANCEL button in ON position, continuity should exist between cable reel 4-pin connector terminals No. 2 and 4 and between terminals No. 2 and 3. If continuity exists as specified, go to next step. If continuity does not exist as specified, go to step 5.
- Remove instrument panel lower left cover and knee bolster. Disconnect in-line Blue 14-pin harness connector, located under left side of instrument panel, above driver's underdash fuse/relay box. Using DVOM, check for continuity in Light Green/Black wire between cable reel 4-pin harness connector terminal No. 3 and in-line 14-pin harness connector terminal No. 8. Also check for continuity in Light Green/Red wire between cable reel 4-pin harness connector terminal No. 4 and in-line 14-pin harness connector terminal No. 7. If continuity exists, go to next step. If continuity does not exist, replace wiring harness.
- Disconnect in-line 16-pin harness connector, located behind glove box. Using DVOM, check for continuity in Light Green/Blue wire between cable reel 4-pin harness connector terminal No. 2 and in-line 16-pin harness connector terminal No. 9. See Fig 2. If continuity does not exist, replace combination switch wiring harness.
- Remove SET/RESUME/CANCEL switch. See SET/RESUME/CANCEL SWITCH under REMOVAL & INSTALLATION. With SET button in ON position, continuity should exist between SET/RESUME/CANCEL switch connector terminals No. 1 and 3. See Fig 2. With RESUME button in ON position, continuity should exist between SET/RESUME/CANCEL switch connector terminals No. 1 and 2. Go to next step.
- With CANCEL button in ON position, check for continuity by probing SET/RESUME/CANCEL switch 4-pin connector terminal No. 1 with positive terminal of DVOM, and terminals No. 2 and 3 with negative terminal of DVOM. Continuity should exist at both circuits. If continuity does not exist as specified, replace switch. If continuity does exist, replace cable reel.
