Test W: Low Tire Pressure Warning Never On
- Turn ignition switch to RUN position. Observe low tire pressure indicator in overhead console. If low tire pressure indicator proves out, go to next step. If low tire pressure indicator does not prove out, perform TEST AE: LOW TIRE PRESSURE WARNING ALWAYS ON OR FLASHING
.
- Turn ignition switch to OFF position. Disconnect instrument cluster harness connector C256. Disconnect low tire pressure module harness connector C927. Measure resistance between ground and terminal No. 2 (Dark Green wire) at low tire pressure module harness connector C927. Resistance should be greater than 10 k/ohms. Measure resistance in Dark Green wire between terminal No. 2 at low tire pressure module harness connector C927 and terminal No. 2 at instrument cluster harness connector C256. See Figure
and Fig 1
. Resistance should be less than 5 ohms. If any resistance is not as specified, repair open or short in Dark Green wire. If resistances are as specified, replace instrument cluster.
