C1438; REAR VERTICAL ACCELEROMETER SIGNAL CIRCUIT

G256924t29: CHECK THE REAR ACCELEROMETER SIGNAL CIRCUIT FOR SHORT TO GROUND
1. Disconnect the ASU electrical connector, CR89.
2. Disconnect the rear accelerometer electrical connector, TL34.
3. Measure the resistance between TL34, pin 02 (GO) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t30: CHECK THE REAR ACCELEROMETER SIGNAL CIRCUIT FOR SHORT TO B+
1. Measure the voltage between TL34, pin 02 (GO) and GROUND.
^ Is the voltage greater than 3 volts?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No
INSTALL a new rear vertical accelerometer, CLEAR the DTC. TEST the system for normal operation.
