4. Measure ILU voltage between these terminals and
body ground:
• 1999-2000 models: Between A28 terminal and
ground.
• 2001 model: Between E15 terminal and ground.
1999-2000 Models:
PCM CONNECTOR A (32P)
Wire side of female terminals
2001 Model:
PCM CONNECTOR E (31P)
Wire side of female terminals
Is there battery voltage?
YES Check for an open in the wire between the
A28 terminal (1999-2000 models) or E15 terminal
(2001 model) and the multiplex control unit
(driver's), and check for loose terminal fit in the

• 2001 model: A (31P) and E (31P) connectors.
7. Press the brake pedals and measure the voltage
between these terminals.
• 1999-2000 models: Between the A32 and B20 or
