TEST S: UNABLE TO AUTO TEST 1. Check Air Suspension Test Connector Disconnect suspension control module harness connectors. Measure resistance in Dark Green/Light Green, Black/Pink and Gray/Red wires between suspension control module harness connector and air suspension test connector. If resistance is 5 ohms or less in all wires, go to next step. If resistance is greater than 5 ohms in any wire, repair appropriate wire(s) and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 2. Check For Short To Voltage Measure voltage between ground and both Dark Green/Light Green and Gray/Red wires at suspension test connector. If voltage does not exist at either wire, go to next step. If voltage exists at either wire, repair short to voltage in appropriate wire(s) and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 3. Check For Short To Ground Measure resistance between ground and Dark Green/Light Green wire and Gray/Red wire at air suspension test connector. If both readings are more than 10,000 ohms, go to next step. If any reading is 10,000 ohms or less, repair short to ground in appropriate wire(s) and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 4. Check Suspension Warning Indicator Turn air suspension switch, located on right side of trunk, to OFF position. Turn ignition on. Observe CHECK AIR SUSPENSION warning light. If light is on, go to next step. If light is off, repair instrument cluster as necessary and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 5. Check Power Circuit Disconnect positive battery cable. Measure resistance between terminal No. 1 (Light Blue/Pink wire) at suspension control module harness connector and positive battery terminal. If resistance is less than 5 ohms, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If resistance is 5 ohms or more, repair open or poor connection in Light Blue/Pink wire between battery and suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If the system check out, at the rear axle there is a hieght adjustment possible. But check that the rear shocks are in place.TEST L: CODE 68 - HEIGHT SENSOR OUTPUT SHORTED 1. Check For Codes Turn air suspension switch, located on right side of trunk, to OFF position. Disconnect height sensor harness connector. Turn air suspension switch to ON position. Perform auto test. See AUTO TEST under TESTING & DIAGNOSIS. If Code 68 is displayed, go to next step. If Code 71 is displayed, replace height sensor. Repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 2. Check For Short To Ground Turn air suspension switch to OFF position. Disconnect suspension control module harness connectors. Control module is located behind right side of instrument panel, above glove box. Measure resistance between terminals No. 3 (Orange/Black wire) and No. 6 (Black wire) at suspension control module harness connector. If resistance is more than 10,000 ohms, go to next step. If resistance is 10,000 ohms or less, repair short to ground in Orange/Black wire. Go to next step before making repairs. 3. Check For Short To Ground Measure resistance between terminals No. 6 (Black wire) and No. 17 (Pink/Black wire) at suspension control module harness connector. If resistance is more than 10,000 ohms, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If resistance is 10,000 ohms or less in this step and/or step 2 , repair short to ground in Pink/Black wire and/or Orange/Black wire. Repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. TEST M: CODE 46 - HEIGHT SENSOR SHORTED 1. Check Height Sensor Turn air suspension switch, located on right side of trunk, to OFF position. Raise vehicle on hoist. Disconnect height sensor harness connector. Lower vehicle. Turn air suspension switch to ON position. Repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. Ignore all codes except Code 46. If Code 46 is received, go to next step. If Code 46 is not received, replace height sensor and repeat auto test. If Code 46 repeats, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 2. Check For Short To Battery Turn air suspension switch to OFF position. Disconnect suspension control module harness connectors. Control module is located behind right side of instrument panel, above glove box. Turn air suspension switch to ON position. Measure voltage between terminals No. 6 (Black wire) and No. 22 (Purple/Light Green wire) at suspension control module harness connectors. If voltage is zero volts, go to next step. If voltage is not zero volts, repair short to voltage in Purple/Light Green wire and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS.3. Check For Short To Ground Measure resistance between terminals No. 6 (Black wire) and No. 22 (Purple/Light Green wire) at suspension control module harness connectors. If resistance is more than 10,000 ohms, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If resistance is 10,000 ohms or less, repair short to ground in Purple/Light Green wire and repeat auto test. TEST N: CODE 71 - HEIGHT SENSOR CIRCUIT OPEN 1. Visual Inspection Turn ignition switch to RUN position. Turn air suspension switch, located on right side of trunk, to ON position. Enter Function Test mode. See FUNCTION TEST under TESTING & DIAGNOSIS. DO NOT select test at this time. Scan tester button should remain in TEST (down) position. Raise vehicle. Ensure height sensor harness connector is connected and that connector and wiring are in good condition. If connector and wiring are in good condition, go to next step. If connector and/or wiring are worn or damaged, repair as necessary and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 2. Check Height Sensor Circuits Disconnect height sensor. Measure voltage between ground and Pink/Black wire and Orange/Black wire at height sensor harness connector. If either reading is not 4 volts, go to next step. If both readings are 4 volts, go to step 4 . 3. Check For Open Circuit Turn air suspension switch to OFF position. Disconnect suspension control module harness connectors. Measure resistance of Pink/Black wire between terminal No. 17 at suspension control module harness connector and height sensor harness connector. Also, measure resistance at Orange/Black wire between terminal No. 3 at suspension control module harness connector and height sensor harness connector. If both readings are less than 10 ohms, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If either reading is 10 ohms or more, repair open in appropriate wire and repeat auto test. 4. Check Circuit No. 432 Measure resistance between ground and Black/Pink wire at height sensor harness connector. If resistance is more than 10 ohms, go to next step. If resistance is 10 ohms or less, go to step 6 . 5. Check For Open Circuit Turn air suspension switch to OFF position. Disconnect suspension control module harness connectors. Measure resistance of Black/Pink wire between terminal No. 8 at suspension control module harness connector and height sensor harness connector. If resistance is less than 10 ohms, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If resistance is 10 ohms or more, repair open in Black/Pink wire and repeat auto test.6. Check Circuit No. 429 Measure voltage between ground and Purple/Light Green wire at height sensor harness connector. If voltage does not pulse 4-6 volts, go to next step. If voltage pulses 4-6 volts, Purple/Light Green wire is okay. Repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. 7. Check For Open Circuit Turn air suspension switch off. Disconnect suspension control module harness connectors. Measure resistance of Purple/Light Green wire between height sensor harness connector and terminal No. 22 at suspension control module harness connector. If resistance is less than 10 ohms, replace suspension control module and repeat auto test. See AUTO TEST under TESTING & DIAGNOSIS. If resistance is 10 ohms or more, repair open in Purple/Light Green wire and repeat auto test.

Put stands at rear of the car, if you get under it and it looses air, you will get injured or killed!
