Circuit/System Testing
1. Ignition OFF, disconnect the harness connectors at the K19 Suspension Control Module.
2. Ignition ON, test for 9,5-16 V between the 12 V reference circuit terminal 32 and ground.
• If less than the specified range, test for a short to ground or open high resistance. If the circuits test normal replace the K19 Suspension Control Module.
• If greater than the specified range, test for a short to voltage. If the circuits test normal, replace the K19 Suspension Control Module.
