Circuit Description

This sensor detects deceleration on the vehicle. The sensor signal is used in ABS & BA & TRAC & VSC control. If the sensor functions abnormally, the ABS warning light comes on.

DIAGNOSTIC TROUBLE CODE

DTC No. DTC Detecting Condition Trouble Area
C1232/32 While vehicle speed becomes 0 km/h (0 mph) from 30 km/h (18 mph), and the condition that GL1 and GL2 signals of ECU terminals did not change 40 mV or less continued in a sequence 16 times.
  • Deceleration sensor
  • Deceleration sensor circuit
C1243/43
C1244/44 Either of the following 1., 2., 3. or 4. is detected:
  1. The condition that ECU terminals GL1 and GL2 values are 1.5G or less or 1.5G or more continues for 1.2 sec. or more.
  2. The condition that the deceleration sensor terminal VGS voltage is 4.4 V or less or 5.6 G or more continues for 1.2 sec. or more.
  3. At the vehicle speed of 0 km (0 mph), after the difference of output value between deceleration sensor terminals GL1 and GL2 becomes 0.6 G or more, and the condition that does not become 0.4 G or less continues for 60 sec. or more.
  4. Deceleration sensor signal momentary open occurs for 7 times or more.
C1245/45 At the vehicle speed of 30 km/h (18 mph) or more, and the condition that the difference between acceleration and deceleration values of computation from deceleration sensor and vehicle speed becomes more than 0.35 G continues for 60 sec. or more.
