Relay Test

Ignition OFF, disconnect the appropriate relay.
Test for 70 - 150 Ω between terminals (85 or 1) and (86 or 2).
- If less than 70 or greater than 150 Ω
  Replace the relay.
- Go to next step: If between 70 - 150 Ω
Test for infinite resistance between the terminals listed below:
- (30 or 3) and (86 or 2)
- (30 or 3) and (87 or 5)
- (30 or 3) and (85 or 1)
- (85 or 1) and (87 or 5)
- (86 or 2) and (87 or 5)
- If less than infinite resistance
  Replace the relay.
- Go to next step: If infinite resistance
Install a 3 A fused jumper wire between relay terminal (85 or 1) and 12 V. Install a jumper wire between relay terminal (86 or 2) and ground.
Test for less than 5.0 Ω between terminals (30 or 3) and (87 or 5).
- If 5.0 Ω or greater
  Replace the relay.
- Go to next step: If less than 5.0 Ω
All OK
