- Turn ignition off. Disconnect CAB 37-pin connector. Inspect, clean or repair connector as necessary. Turn ignition on. Put DRB in voltmeter mode. Using DRB, check voltage on CAB connector terminal No. 22 (White/Tan wire). If DRB displays battery voltage with brake pedal depressed, replace CAB. Perform TEST VER-1A. If DRB does not display battery voltage with brake pedal depressed, go to next step.
- Turn ignition off. Disconnect brakelight switch connector. Inspect, clean or repair connector as necessary. Connect a jumper wire between chassis ground and White/Tan wire at brakelight switch connector terminal No. 2. See Fig 1. Put DRB in ohmmeter mode. Using DRB, check resistance of White/Tan wire at CAB connector terminal No. 22. If resistance is more than 5 ohms, repair open in White/Tan wire. Perform TEST VER-1A. If resistance is less than 5 ohms, adjust or replace brakelight switch. Perform TEST VER-1A.
