DLC1

Iei-23-1-A

P  Turn ignition switch ON

C  Measure voltage between terminals Ts and E1 of DLC1.

OK  Voltage:  10 – 14 V

NG

OK  If ABS warning light does not blink even after Ts and E1 are connected, the ECU may be defective.

2  Check for open and short in harness and connector between ABS (&TRAC) ECU and DLC1, DLC1 and body ground (See page IN–30).
