Note: The following section applies to Hermann engine analyzers, tests and connections for Bear DACE engine analyzers are similar, please refer to instruction manual supplied with EI (distributor-less) test adapters. When diagnosing starting or warm up complaints, do not check engine at operating temperature, instead proceed according to specific complaint.

Air intake hose at intake air temperature sensor (IAT) Ignition coil cover (on top of valve cover) Primary ignition side connections: (HFM/ME) 3 cables from primary side adapter (055/1) to ignition coils (T1, T2, T3) Remaining cable from 055/1 to connector T1/X on the EI adapter (055) Impulse counter scan tool adapter (075) (excluding model 124) to data link connector (X11/4) Cable from TN connector on EI adapter (055) to X11/4 (socket 10 for model 124, socket 17 for model 202, socket 13 for models 129/140/210) Secondary ignition side connections: (HFM) Red trigger clamp from engine analyzer to metal handle on adapter (CD1222) and and conector for kV trigger (061/1) Red trigger clamp from adapter (CD1222) to no. 1 ignition wire Harnesses with kV clamps (nos. 1, 3, 5) to adapter (CD1222) kV clamps (063/1, 063/3, 063/5) to secondary ignition wires for cyls. 1, 3, 5 Harnesses with kV clamps (nos. 2, 4, 6) to adapter (CD1222) kV (coil) pickups (063/2, 063/4, 063/6) on top of coils for cyls. 2, 4, 6 Power supply for EI (distributor-less) adapter (055) Black lead (sw) to vehicle ground, red lead to terminal 15 (red) of X11/4 Remove, reinstall Remove, reinstall Connect, disconnect (between primary connections at coil) Connect, disconnect Connect, disconnect Connect, disconnect (for TN signal) Connect, disconnect Connect, disconnect Connect, disconnect Connect, disconnect Install, remove Connect, disconnect Connect, disconnect

Note:
Due to the differences in the designs of the Bosch and May and Christie ignition coils; different secondary pickups are required.

Diagnostic connector (060) from engine analyzer (030) to 9 pin diagnostic socket on EI (distributor-less) adapter (055) Vehicle information Engine analyzer (030) and EI adapter (055) EI (distributor-less) adapter (055) Connect, disconnect Input Set to 6 cyl. (refer to following pages) Set according to table (refer to following pages)

Note:
If the the oscilloscope pattern is upside-down (displays 2 ignition voltage lines at the bottom of the screen) or shows no pattern (with engine running), select a different firing order selection at switch D on the EI (distributor-less) adapter 055 (the base setting is 11; select 12, 13, etc. until correct pattern is displayed).

Connect D.C. inductive (pickup) clamp (065) to battery ground cable (model 124) or to ground strap between the transmission and chassis on left side of vehicle (models 129/140/202/210) Exhaust vent hose (014) Engine coolant temperature approx. (80 °C) Connect, disconnect Insert, remove Engine at operating temperature
