4 BLK GND (Ground) Ground for the TPMS control unit Less than 0.1 V at all times
5 GRN LF SIG. (LF low frequency signal) Detects the signal from the left-front initiator For the first 5 seconds after turning the ignition switch to ON (II): pulses 4.5-6.5V
After 40 seconds with ignition switch ON (II): less than 0.1V
6 LT GRN RF LF SIG. (RF low frequency signal) Detects the signal from the right-front initiator For the first 5 seconds after turning the ignition switch ON (II): pulses 4.5-6.5V
After 40 seconds with ignition switch ON (II): less than 0.1V
7 LT BLU K-LINE (Data link connector) Communications with the HDS ---
8 PNK IG1 (Ignition switch 1) Power source for activating the system Ignition switch ON (II): battery voltage
Ignition switch in LOCK (0): less than 0.1 V
10 YEL +B (Battery positive) Power source for the TPMS control unit Battery voltage (about 12V) at all times
11 RED CAN L (F-CAN communication signal low) F-CAN communication circuit Ignition switch ON (II): pulses
15 LT BLU LF GND (LF low frequency ground) Ground for the initiators For the first 5 seconds after turning the ignition switch ON (II): less than 0.1V
16 GRN LR LF SIG. (LR low frequency signal) Detects the signal from the left-rear initiator For the first 5 seconds after turning the ignition switch ON (II): pulses 4.5-6.5V
After 40 seconds with ignition switch ON (II): less than 0.1V
17 GRY RR LF SIG. (RR low frequency signal) Detects the signal from the right-rear initiator For the first 5 seconds after turning the ignition switch ON (II): pulses 4.5-6.5V
After 40 seconds with ignition switch ON (II): less than 0.1V
20 BRN LF PWR. (LF low frequency power) Power source for the initiators For the first 5 seconds after turning the ignition switch ON (II): pulses 0.3-6.5 V
After 40 seconds with ignition switch ON (II): About 0.3 V
