Inspection Procedure
WARNING: This page is about a different variant/trim than selected.
- Inspect fuse (ECU-IG).
- Remove the ECU-IG fuse from the instrument panel J/B. See Fig 2.
- Check the continuity of the ECU-IG fuse.
OK: Continuity
NG , replace fuse.
OK , go to step 2.
- Inspect terminal voltage (B).
- Remove the cruise control ECU assy with connector still connected.
- Turn the ignition switch to ON.
- Measure voltage between terminals 2 (B) and 16 (GND) of the cruise control ECU assy connector. See Fig 3.
OK:
Voltage: 10-16 V
OK , proceed to next circuit inspection shown on problem symptoms table. See PROBLEM SYMPTOMS TABLE under PROBLEM SYMPTOMS TABLE.
NG , go to step 3.
- Check harness and connector (between cruise control and body ground).
- Measure resistance between terminal 16 (GND) of the cruise control ECU assy connector and body ground. See Fig 3.
OK:
Resistance: Below 1 Ω
NG , repair or replace harness or connector.
OK , check and repair harness and connector between cruise control ECU assy and battery.
- Measure resistance between terminal 16 (GND) of the cruise control ECU assy connector and body ground. See Fig 3.
